The motors aren't that powerful, you'd need to go to industrial applications for that. Cavitation is when water vaporizes on the surface of an impeller, which isn't happening in these hobbyist-level motors. With cavitation, air isn't in the voids formed but water vapor is. With CLCs/AIOs, it's just air bubbles getting pulled through the loop (not cavitation).

@@santisvander Should be fine, just make sure the pump isn't at the top of the loop. The air bubble will be split between the top of the tank on each side, which should give you plenty of space.
@@elfo7 The key is to ensure that the pump is NOT at the top of the loop. Tubes going into the top of the radiator is fine as long as the actual pump is lower. This message gets a little lost in this video with a great deal of detail. The goal is to avoid air in the pump and the way to ensure this is to apply physics - air will always move to the top of the loop.
Lol I know I am now... it's funny he specifically calls out NZXT cuz I put the pump in how it said in their manual for front mounted installation...Yikes 😅
I was initially going to mount mine at the front with the tubes up, but got the shits fighting the tubes to make them look good, so I fitted it as a top exhaust, tubes down. So I won't be opening my case :)
Well... there is one interesting material called ALON (Aluminium oxynitride) which is... transparent aluminum. It can be any shape since it use powder. So yeah, small (or not so small) windows are possible to see bubbles.
I’m currently building my first PC and is gathering all my parts, but had no idea that positioning was that important. I thought you installed your cooler as normal out of the box and everything will run its course 😅. I can’t imagine frying my PC/motherboard from being reckless lol. Thanks for the video!
@@Ash4med its the same principle of holding your water bottle straight and the air stays up top... nothing to do with cooling or pcs. just fluids acting up in a normal manner...
Swiftech H320 Prestige, has clear under mounted reservoir and CPU block, and primitive RGB. I still use it to this day, pretty nice unit and fun to watch the water go around.
Considering what case manufacturers seem to be doing with the front of cases I could totally see it lol. 2 120mm fans, with no where for the air to go because there's glass with RGB on top of it.
This was incredibly informative and educated me on the science behind AIO water cooling so I could make more informed decisions with my build. Thank you very much!
fist of all hes kind of wrong with it cus back and top is the exost fans that blow hot air out ur pc now having ur radiator on top ur heating up the cooling as the hot air blow thro the radiator resson for front mounting cus front is the air intake ware it suck the cool air up and with radiator there now u got cool air blowing thro ur radiator cooling the liqued down inside alowing for cooler temp on cpu its phisics and commen sens
@RedEye Directive Gaming try corsair case like the the rgb 7000x rgb I think it's called come with icue fans 4 of them and corsair icue rgb box to control the rgb I like it or u can try 1 of there ether case like the 5000D I think it is
Always wondered if radiator orientations mattered, but all the other videos only talk about thermals, and not about what happens to the radiator and noise etc. So thanks!
@@Skelath Such a small volume of liquid that "changes" properties, from liquid to steam, then back again.. as it falls to the bottom of the heatpipe. Additionally, the liquid is "moving" by gravity, and not a pump... giving no mechanical noise.
@@Mr1Tanker To add one more point to this, it's also moving via capillary action - i.e., it's not "dripping", and more flowing. As an example, when you turn the sink on and hold your finger in the water stream pointing down, when you move the tip of your finger, the water sticks to it and gets redirected. When the water is flowing like that, it doesn't make any noise - all the noise is from the aerator, or the stream hitting the basin of the sink.
@@Skelath because passive cooler have no mechanical pump to list the fluid in the heat pipes, it works purely off evaporation (I want to say convection, but I think that's technically incorrect). The only moving part(s) would be the fan(s) and that's a whole other discussion...
Edited to include that this TLDR is just a quick recap for those who have watched the whole video and have a full picture understanding of the reasons why and why not. I STRONGLY encourage viewers to watch the whole video and the follow-up (th-cam.com/video/tU7D6y_QYcI/w-d-xo.html) and not to start panicking about their set-ups. Apologies to Gamers Nexus and everyone for any misinformation this comment might have caused. TLDR: Top-mounted radiator: Yes Front-mounted radiator: make sure the tubes are coming out from below, not the top and make sure the pump is below the highest point of the radiator. Bottom mounted radiator: don't. just don't
I just built my newest PC a few weeks ago and I am so thankful to find this video! I installed the AIO cooler just like you said . I have a cooler master 280mm with the tubes down, going up to CPU. I am having no problems at all! Thank you so much!
definitely dont listen to corsair about how to mount it. this video made me die laughing. its so bad. corsair should be ashamed. th-cam.com/video/1GcSDODt528/w-d-xo.html
Undid my rookie mistake and flipped my Radiator just the other day, it’s quieter already and looks a lot better. Really nice to know *why* it’s quieter, better temps etc.
My corsair aio cooler on my 4770k has lasted like 9 years, still going, understanding a little about pump head, how pumps work etc helps alot, great vid
@@Marblewho Front, but the tubes at the top. I have a 9900KS and it was impossible to do any stability tests (I was doing some undervolt to drop the temps). Now i can do some tests and the temperature not reach 100C
The lengths y'all went to for the purpose of proving a pretty obvious point about AIO's is insane. You're all insane - I hope you know that. And that's why we love you.
I bought a prebuilt a year ago and have always been struggling with high CPU temps particularly in high CPU-Intensive games such as Rust. I have a single fan AIO. I was playing Rust today and noticed my CPU temps were 95-100°C... I finally had a google and came across this video. Turns out the AIO was upside down exactly like at 18:16 I unscrewed and flipped the AIO then booted up Rust. Max 65°C. Thanks so much for this video and the in depth explanation Steve & team.
This is the first time I've seen a "STOP DOING" clickbait type titel that I actually was doing wrong. Shut down the pc* and flipped the radiator. And yes the boot up blub was removed, and no more gurgles.... And it even runs cooler, though that is very very likely to be mainly caused by the fact that while at it I removed the radiator's winter coat.... What's even worse, I work in oceanography and know my way around turbulent flow... I should have known, but never actually thought about how to do it, just mounted it and it (kinda worked). *By shut down I mean tried swapping it hot, then decided I needed a bit more room and pulled the cords out of it.
I say don't feel bad. It's not your fault that case suppliers provide bad info and the product documentation isn't the best. Blame marketing for not making sure the info is well known enough. It's not your job to be thinking about PC parts, it's the people supplying them.
This is frustrating for me, mine is set up in a way that is not ideal although not the worst according to this video but the water lines on my Aio aren't long enough to install it any other way.
I had no idea this was even a factor and me and someone had a long talk about air in the lines when I was building it my opinion was that the air would be better at the top near the barbs ala nzxt config but they thought it would be better for them to be in the reservoir. Mine is mounted on my 2080 and I'm really curious to know how much of a difference it might make because I don't really have any complaints atm.
Would this be a viable option if you cut a hole in the desk/surface that you ARE putting the pc on? That way the exhaust fan isn’t suffocating when you flip the pc and all the usb lines can fit through easily with no problems. 10/10 would look wack kek
I've been looking everywhere for the answers that literally only this video provides. I'm building with an AIO for the first time in two days. I did so much research and was convinced until this moment that tubes up vs tubes down didn't matter for front mounted radiators. I'm so relieved to have GN finally provide a definitive answer on this, yet pissed that AIO has been around for God knows how long and only now is there a correct answer floating around as to how you're supposed to mount your shit.
I'm in the same boat. Just got my Arctic freezer II (finally) and have been looking for such a guide as this to know the best way to install it. Once again GN to the rescue!!
Very good info indeed. So just to make it clear ... If you have a Corsair H100i Titanium RGB cooler (like i just build) .. mounting the radiator as Corsair shows in their mounting instructions for the 465 case in the front with the tubes at the top!!!.... The correct way would be to turn the radiator around with tubes down .. Is it still ok to have the tubes come out at the right side of the cpu block/pump so you still see the "Corsair logo" the right way ?? I'm amazed that even the companies building the things show you an incorrect mount in there mounting instructions. But hey if we botch the mounting up like they instruct us too they "maybe" sell more Aio's if the user don't switch to another brand the next time. I have had no issues with water gurgling for the week the machine has been running. The Corsair Aio and their LL fans arent the most silent around but its ok as long as you don't have a very demanding cpu that need higher rpm to keep cooled. I am currently hitting in the upper 60's degrees on my R7 3800X package when under 100% load (67 the highest I've had), while having no higher readings than 35 degrees from the Aio. I take that is the water temp it messeures ? These readings are with all 5 Fans in the system set to "Quiet" If I hit Extreme settings tey drop to around 30/60 degrees. But if the Aio will live longer, I'm gonna flip that radiator. the tubes should be long enough. I just wonder if they have made longer tubes on the H115i if you have to go all the way from the bottom of the case and up to the cpu, think the H100 would have a problem. But as these 3 Fan cases often have a psu shroud that covers 3/4 of the intake from the lower fan, noone in their right mind would place a 2 fan Aio in the bottom of the 3 front fans. Plus on the 465X case from Corsair I'd have to remove the HDD case to have enough clearance for an H115, why I saved a few bucks and went for the H100. Thanx for a good video Steve. You propably didn't have the time, but next time just to clear it all out for the buttheads or non english native viewers of us, show a few shots more of correct vs incorrect mounted tubing configs for both front, top and back mounts of the Aio's. As I see it the bottom mount would propably only be needed for those ultra compact cases where you just barely can mount the Aio at the bottom.
19:46 - I work in medical devices industry for 16 years now in R&D. Part of my job is testing of these devices in the silicone models of human blood vessels systems. In those 16 years I had to get rid of a lot of air bubbles :D Your video is great, however I only partially agree with the setup at 19:46. You created kind of U-shaped loop. The problem is that if by any chance during installation you trapped some air in the pump (even if the pump is lower than top of the radiator), there's NO WAY the air from the pump will travel down the loop toward the bottom of your 'U'. Air bubbles are gonna remain trapped in your pump.
omg i just turned my case over and my temps went to 30c to 26c but i still going to flip my radiator or maybe mount up top if that what he said worked too but thank for giving me that idea my case looks funny upside down right now tho lol.
Hi. He's right and wrong. As long as the cpu pump is lower than the highest point of the tubes on the rad, it's fine. Hot or warm coolant will rise faster as it's molecules are more spread, and it will have no issue travelling upward if the top of the raditior is higher than the pump, in a closed loop. Once the hot coolant is at the higher point on the radiator, gravity will let it fall down into the rad, and cool it as it fills with enough pressure to send the cooler liquid back up. Once running it won't matter. Only the initial cycle likley which has low load anyway. Provided there's no leaks and pressure is maintained, it should make almost no difference... It won't kill your pump, in a healthy loop and properly filled one 🤷
@@Nick-GR Then people who weren’t as technically aware is now informed so yeah, this video still would have shaped thousands of PCs. Your comment is pretty irrelevant.
I built PCs and repaired them since the home PC was introduced, I started with Tech when the Atari game console was out and was the go to repairer in my neighborhood. I also tinkered with cars my whole life and know the orientation of a car radiator, the thing is I learned how these are installed correctly from working on cars. I am not a genius I just know the physics of how a pump for a radiator in a car works.
For almost a decade, I've used air coolers on all my builds until a few months ago where I cracked and bought a 360 AIO for my main rig. For AIO orientation, I asked many of my friends who use AIO, searched TH-cam, and google searched as if I was doing a project, but alas I did not find any answers. Until I remembered Steve mentioning in one of his videos not to mount AIOs like @17:56, but still no concrete answers. I ended up mounting it like @13:00 but with the tubes near the back instead. This is a great video since this is the only video that I've seen that actually answers how to properly orient AIOs.
I ended up mounting my AIO's rad to the top of the case simply because that seemed to cause the least stress on the hoses, had no idea I was saving it from bubbles and other issues too, now that I know how useful that is I'm defginitly planning it into future builds
I heard that throwaway comment on another vid too, changed orientation and saw an instant improvement in coolant temp. I've only had the aio installed a month or two incorrectly so fingers crossed it didn't cause too much damage.
@@UNSCPILOT i have 2 computers with an aio one is on top and the other is on the rear exhaust simply because it's literally the only place on these 2 cases that could hold the radiator.
And this is why I always always tell people to NOT use AIOs unless they intend to do OCing and the majority will never OC and does it just because it makes their case "authentic pro gamer". You can't do much wrong with a fan - it's usually quieter, cheaper, easier to install, works on all cases (only need to take RAM / component clearance into account), you can't really fuck it up that it breaks and you have so many choices for fans + on a massive cooler, if the fan breaks you can replace it. If a AIO pump breaks .... not to mention potential leaks, installation issues, cost, noise level, your case potentially not working (which you always find out after you try to install it of course).
Honestly one of the most informative and easy to understand videos i've ever watched. I plan to upgrade to an O11D Mini SNOW and a DeepCool AIO and this information will be invaluable since it's my first AIO.
4 Years ago when i bought my first AIO the dude at the store told me to just put the radiator as high as possible. Told me to put it in the top with the fans exhausting the air through it. After this video I understand exactly why. Thanks random KTM employee :)
Just bought my first water AIO and after reading around was starting to have doubts about installing it because of so many people complainign about gurgling and pump whine etc. I had all but decided to return it in favor of the "big ass noctua" that's proving so popular (and MUCH cheaper), however it seems it could well be they were all just mounted wrong.
@@dumbodum the air cooler featured in the video wasn't a random air cooler but rather the best one noctua had to offer. More often than not AiOs beat air coolers
The noctua n15 is comparable to many 240 or 280 rads in terms of cooling, thermals and sound, based on GN charts from most recent best of video. It can’t compare to the 360 or 420 rads, but if you don’t need that much cooling, then that kind of air cooling is totally viable. GN tested the n15 with a i9 12th gen, so it was up to cooling that stock. I like the safety of air cooling - I personally prefer parts that don’t have even the potential to fail in a way that will damage other parts, but that might be my engineering background. I am thrilled aio are so so much more reliable than when they first came on the market tho.
Unfortunately, front-mounted, tubes-up is often the only way a particular liquid cooler will fit it a particular case, either because there aren't appropriate mounts anywhere else and the tubes are too short for tubes-down, or because there's an issue with clearance related to the motherboard or the RAM that prevents mounting it in the top of the case.
Yeah, that's a common issue, unfortunately. The good news is that it mostly causes noise and is less likely to cause long-term damage (but the noise may become annoying over time).
@@GamersNexus Yea when y'all showed Barb's at bottom it didn't look like a graphics card would be able to fit in there is that why it wasn't installed.
Can confirm that this is an issue with my Liquid Freezer 2 280. The tubes are too short for tubes-down but luckily GN below says it's just a noise issue for the most part and I honestly don't really hear anything from my AIO so I guess it'll be fine for now?
I don't think you'll ever get the credit you deserve. You really provide the most objective and supportive information on PC building on the biggest video platform in the world
The problem I find is the tubing on these AIO coolers is nearly always too short to mount them properly with the tubing at the bottom of the radiator as described in this video. If the manufacturers would just make the tubing a bit longer this might actually be a possibility, but pretty much every build I've done that isn't top mounted has to be upside down due to the pitifully short length of tubing provided on these units.
@@jamisonmunn9215 just seems crazy to me lol I've built maybe 13 or 15 cases in the past 2 years or so. And never had any issues. The inky issue I've had so far is actually with my personal build. The hoses are too long for the mesh 2 case I have by Lian Li. So they look ridiculous, bit annoyed by that, but it's by corsair, the liquid ice 3 fan rad
I have my rad front mounted like the NZXT one in the Picture, I am just trying to understand if I should try to put the tubes flipped upside down now or not. I don’t think my case will have room to mount at the top with my 280mm X62
Yeah, I mounted mine like the AIO makers do it... I have a 360mm AIO that can only be mounted vertically on the front of the case so I can't top mount it and the tubes won't get around my 5700XT Red Devil to flip it in the front so I'm screwed. I guess it's a good thing my 3700x came with an air cooler in case it fails on me eventually. I just built this computer last month so I have a long way to go anyways.
This type of content, along with things like calling out MSI over their shady reviewer relations, is what make me confident that GN is a trusted Source of tech knowledge.
The push from GamersNexus got case manufactures to bring back mesh cases, now we may see RGB tempered glass AIOs. AIOs may start looking like mini custom loops now. On a serious note, I really wanna see a case manufacture bring back side mounted fans. Come on now, you guys can bend glass. I don't see why you cant put a 200mm fan on a side panel.
Yep. You must use the top of the radiator (I/O pipes below) as an air trap. I installed a vertical radiator, so the air trap was above the pump n block by about 3.5cm to ensure it gets no air gets into it too. It worked flawlessly. Very quiet, very efficient, faster on loads, and temps were the absolute best. Because if the pump is too low, if there is any air is in the top of the radiator, the pump has to push water up OUT of the IN radiator to flow into the OUT radiator. To have gravity place an immediate resistance onto the pump is not optimal. I feel, even if you have a top mounted radiator, the pump too low will have to push water upwards into the IN radiator and rise up before it will come back out of the OUT radiator. Keeping the pump just below the air trap with as little of the res water above, in a 100ml system, will reduce static pressure on the pump by at least 90 grams even when the PC is off. But the pump and IO pipes MUST be below the air trap and the IN line to the pump n block on top above the pump n block OUT line as in the video^ .
I honestly never knew this, I always have mounted my AIo’s with the tubes coming out the top mounted at the front of the case! I always did this due to the manufacturers photos/ from seeing other you tubers do this, crazy how know one has mentioned this before
The pump for almost any cooling device whether it be a pc or car should be below the highest level of liquid, this ensures that liquid is constantly being flowed through the pump due to height and gravity. Dry running pumps can cause many problems and eventually cavitate them.
Well put. I think 3 minutes of this video could have been omitted by just simply saying “make sure that the afferent line to the pump is being fed by a reservoir that definitely has no risk of air accumulation - being below the fluid-air level.”
in any way pump and temp will separate dissolved air. for avoid that, cool agent must be warmed max as well cooler itself and only in that condition it must become watertight
It has been 12 years since my last PC build due to going to laptops. Your channel has been very helpful getting back up to speed with current tech for an upcoming build I have planned. Great channel.
I'm glad I found your video. I'm no pc guru. I've decided to build my own PC because I don't want a pre-built system. I love how you explained everything in laymen terms. So now I can consider many factors before making a purchase ie. Cord length and how the manufacturers orient their radiators in their products and install instructions. Thanks!
I just purchased an Arctic Liquid Freezer 2 A-RGB 360 cooler (new RGB version of the original, released on May 13th 2021), they are literally linking THIS VIDEO in their web based installation instructions. You know you're doing something right when the manufacturers link your video as part of their education on how to use a product! Great job GN!
I asked for evidence to back up some of Steve's claims a few months back when he commented on orientation of an AIO (front mount tubes up or down), i'm not sure if he read the comment but he delivered anyway 👍🏻
Love this type of content. I installed a Kraken x61 on top for a Xeon x5650 running at 4.72 GHz back in 2015. That AIO was getting roasted until 2019, when I installed it into my Ryzen 3800X rig. Both PCs have been used for gaming or mining 24/7 for 7 years with the same AIO. It's still going.
Similar story for me. I run a 7-year-old x61 that cooled an FX 8320 at 4.6ghz for years and now a Ryzen 3600 at 4.3ghz. Still doing fine but I would like another way to control the fan/pump speed other than using the CAM software. 😁
same with mine. I have to keep my 240 fans going to the top of the case for the cpu. Then my gpu aio is going to the back which works fine. Ive never had issues though
This is super-useful and intuitive in retrospect. I recently cleaned my pc and ran into high CPU temp errors afterwards (probably shifted air around). I was about to dump my AIO and thankfully came across this gem of a video. I had a front mounted radiator with the pump being barely above it. Switched to top mounted configuration and now my CPU runs cooler than ever! Thanks GamerNexus for once again!
This was extremely eye opening to me. I've been building computers for a long time now. I've almost always used AIO's. I honestly never knew this. And I pride myself on trying to know every in and out when it comes to thermal dynamics. This is embarrassing that I didn't know this... I'm grateful again, like always, that your 100% always for the community and NEVER the manufacturers/distributors. This is a HUGE problem in our community to say the least and you are a shining light IMO for always being the one to address what is affecting our community negatively. I admire you greatly and just wanted to thank you for doing this video
i just got my corsair AIO last week and built my first pc. my tubes were on top which my radiator below the cpu pump. I'm so glad I watched this video and fixed it! my tubes are now on the bottom and the radiator is above the cpu pump! thank you!
This mostly applies to AIOs. In custom loops you generally have a reservoir/pump combo where the pump is always under the Res and will always be submerged.
@@AAWT probably? If the air pocket forms at the side where the CPU contacts, conductivity will decrease. Although it might vary on the structure, Even a tiny air pocket on wrong place might be crucial as it would be a dominating factor of thermal resistance. On the other hand, high flow rate near the pump might prevent air from accumulating.
Doing research on my first build. Glad I saw this video before starting it. I was going to install the AIO exactly the way you said NOT to. Now that I know this I will make sure to install the radiator at the TOP of the case. Thank you so much for saving me from making a massive mistake right off the bat.
I was thinking of going to an AIO (for the first time) to move away from my stock cooler that came with my 3600X after finding out that it wasn't keeping my CPU at temp levels I was happy with at idle. I have to admit, reading reviews of them on sites like Newegg, and Amazon really turned me off of the idea. Then I found this video, and it completely changed my mind. THANK YOU Gamers Nexus, for putting out quality content for people like me, who have no idea what they're doing with liquid cooling and want to dip their proverbial toe in with something simple like a prebuilt AIO. My new AIO is currently running soundlessly (except for the slight whir of the fans) at the top of my case and keeping my CPU MUCH cooler than the stock wraith was able to do, even with updated case airflow, and I credit this video for restoring my faith in the idea, seven months after it was published.
Every front mounted AIO I've ever seen has had the tubes at the top, I always thought it was a bad idea, and I always did tubes at the bottom myself, but I never knew if it actually mattered at all. Then this video pops up in my feed randomly, 2 years after it was posted, and finally I'm validated lol.
It's not that it's a bad idea, very often mounting it tubes bottom will make it hard or impossible to mount longer gpus. As long as the pump is below the highest point of the loop it should be ok. The worst thing that can happen is some bubbling noise in a radiator. I am currently using be quiet! silent loop 2 mounted like that but it has a port for refilling and it comes with a bottle of coolant so if it ever starts to be noisy I will just refill it. It is suboptimal but there won't be any damage.
@@afgncap Thank you. This wouldn't be such an "embarrassing topic" to him if he'd have first considered what happens to the hoses in a bottom mounted 360mm radiator setup in order to get them past a 340mm long video card with a rollcage for a frame in order to get to the AIO pump. Or if he considered a problem like mine - where a dual SATA HDD cage is sitting close enough to where the tubes exit the radiator if bottom mounted that they have to be doubled back on themselves 10mm out from the fittings just to get over the cage. I'm going to go with "that would be a worse idea than any top hose mount".
So... a lot of us are pretty much screwed then. I mean, if I mount my MasterLiquid ML240RS with the rad up front (tubes up), I'm basically introducing bubbles (and the gurgle noise, which happens but is not very common) into the top of the rad. I don't think I can mount it tubes down because of the GPU, but I'll try it tomorrow, and mounting at the top is possible, but I may not have the space to do push/pull the way I have it now..... It's also rather infuriating to think that, even though I have considered this before, there are no directions on this on pretty much any manual. In fact, it lead me to believe there was some unknown system built in to let air bubbles escape.....
I have the exact same problem, looks like going up top is the best option, but I know for a fact that push/pull would be imposible because of RAM clearance issues ( I tried it when I put my system together in the first place)
I had to put mine up top. The instructions were garbage and I had no idea what to do because of it just being pictures and poorly made ones at that. Hoses weren't even long enough to put them at the top of the front panel.
>So... a lot of us are pretty much screwed then. Yea p-much I'm running a Kraken x62 AIO in a fractalDesign Meshify C which barely has enough room to mount the radiator at the front if your graphics card is a long boy. Having the tubing at the top vs the bottom could be the difference in getting that radiator to fit and it's what I'm facing right now. Can't mount the radiator up top cause then it conflicts with the motherboard.
I have a narrow micro atx case. It can't fit a decent air cooler because they're too tall. My only option for managing thermals with an overclock is water cooling but there's no option for top mount and my HDD tray blocks any hope of mounting the rad tubes-down. I'd may eventually get a new case but it is perfect for my desk size. There's zero noise aside from fans and my temps are fantastic, so is there really a problem here?
this made me double check that my closed loop system was installed properly, and I did indeed mount the tubing at the bottom :D You guys have really useful information.
Sadly most AIO's have short tubes and mounting them "correctly" isn't viable, specially with a big hardware piece that you didn't mention in the middle, the GPU. In my case for example if I mount the AIO like you say the tubes are stretched as far as they can go and they push against the GPU, putting a ton of strain on the PCI-E. I agree with the testing but most of the time that's not viable in a real use case. Maybe companies should make AIO's with longer tubes.
@@belfalasvinyamar except just saying to try doesn't work when it's a physical limitation. Also doesn't help if it's 360 mm radiator that goes down into the shroud at the bottom. Hard to bend the tubes around that
@@chrisgent45 Yeah Im using the Arctic Freezer II and I can't mount it with tubes down. It's impossible to route the tubes from the bottom with a GPU installed. I disagree that too mounting is the best way too...all heat inside a PC rises to the top. Your pump *might operate a bit better this way but your temps will also be significantly higher. I've done extensive temp testing with my 360 rad at the top vs front. Front is much better than top.
@@GSP-76 yeah, Bitwit did a video about top versus front placement, and front resulted in 10 degree cooler temp than top, with the discernable difference in GPU temp. Thinking I will have to order a 280 mm AIO instead of 360.
consumer- I need to rma my aio nzxt- How did you have it mounted? consumer- Just like you showed in you pictures nzxt- Well that was wrong. Denied. Bwahahaha
Dropped almost 4 degrees on my side mounted rad 3950x going from tubes at the top to tubes at the bottom and that's with the pump below the top of the radiator. Thumbs up from me.
I moved my rad tubes to the top and my temperatures actually went up a couple degrees. Probably cause the fresh air is not blowing directly on the radiator anymore.
i literally just checked under my desk if i got my AIO mounted correctly lmao (im safe, nice). but honestly, it makes tons of sense and im wondering why no one talked about that before. great video guys!
I’ve been running my PC AIO’s incorrectly for the past 7 years! Found this video 4 years late! Going to crack it open and correct my orientation and hopefully get another 3-4 years out of my system. Thanks!
@@mig23zcyther ikr, i havent seen a front mounted 360 rad with tubes below on the internet, ever! Well he said the only issue with front mounted tubes on top is the noise, mine doesnt do it, so i guess were fine?
@fran i hope so too! I have a 280mm nzxt x62 that i got 1 1 1/2 year ago so hopefully it will last a couple more years or at least by the time I’ll decide to replace it with a new one. 😅
@@fran117 yeah same mine doesnt make any sound except for the fans that i have on them. plus its impossible for me to front mount with tubes on bottom because of my gpu and case size
Mount inlet/outlet tubes at the bottom of the heat exchanger; top of pump mounted at least a couple cm below the top of the heat exchanger. Any air in the system should eventually collect and stay at the highest point of the loop, which ideally will be the 'tank' space at the other end of the heat exchanger from the inlet/outlet tubes.
For me, who works with pumps in the daily life in the oil field this is 101 basics. Quick google told me the pump in a AIO is a centrifugal pump. Shortly put, they have very bad vaccum lift and must therefore be primed. What that means is, the tank should be placed higher than the pump, that makes gravity fill the suction side of the pump 100%. Simple rule, keep the low and everything else high. Poorly primed pump increase chance of foam/caviatation. This causes noise, at high pressures it could cause damage (not very likely in an AIO).
I picture these corporate marketing reps having mini panic attacks every time they get a notification that GN has posted. "My god, the thumbnail has TWO skull & crossbones. Issue a code red and convene the marketing team immediately for an emergency meeting!"
I bought an NZXT H510i case and Kraken Z63 AIO, installed it the way it said in the manual and pics. My mind is blown at how wrong it is. My next build, I'm buying from a different company. This is by far my favorite and most technical and informative TH-cam channel I've ever seen in TH-cam. Thank you GamerNexus, for your expert and highly technical, accurate and helpful videos!!
3 years later, this is still the most informative video on liquid coolers and how to best mount them. There are many different types of liquid coolers, and the same solution will not apply for all of them. This video provides an in-depth explanation that helps people find the best orientation for their liquid cooler on their own.
After finding out about this, I'm surprised to see how many rigs have the pump/block as the highest point in the system because of how the case is designed. A ton of cases have the mobo mounts so high in relation to the radiator mounts that this problem would be unavoidable with pretty much all AIOs.
Same thought. Even with a massive case like TT P8 Core the motherboard is so close to the radiator/fans that assembly is difficult and risky sometimes.
@@mothambo Go with a Gigabyte C200. Super cool, classy case, and has TONS of space for mounting the cooler on top of the mother board. I'm having around 2-3 inch free space between my 56mm AIO and Ballistix RAMs(The closest thing to the AIO)
No excuse... my old ass case has no mounts for a radiator at ALL and is super cramped for an ATX case. So I got out my drills and sheet metal cutters and mounted that bad boy on top so it doesn't share the GPU and mobos air
flashback to the LTT Tech Support Challenge, remembering Steve with a second of frustration at the AIO set with barbs up by the hosts. I thought this would be addressed when I saw thumbnail for this video... :)
When I was building my PC a couple months ago I watched 5 videos on how to set up my AIO with a front mounted radiator and they all had the tubes at the top. Thank you for shedding some light on this. Also flipping a radiator was more of an ordeal than I thought it would be.. Edit: I was not experiencing any noise or issues, but just wanted to be safe. Edit:: You may want to inform your buddies Linus and Jay about the stuff in this video
Awesome video. Mad props to you and your channel. I remember when I first installed an AIO on my 2500K and was searching for the proper way to mount it... (almost 10 years ago I think) Came across some pretty stupid suggestions that made me doubt my ...education... (physics was probably my favorite subject in school) I was going through sites and some videos and was constantly thinking "that can't be right". Fast forward to recent years, I've been low key looking at a replacement case for a "secondary" PC I have and bad radiator placement is very common on many of products pictured.
19:53 this is Gamers Nexus ideal location of pump and radiator inside case to reduce noise (whine/gurgling) and is overall better for longevity of AIO (if case and length of tubing on AIO permits).
@@oisintimon317 top mounted is he's preferred but he said if your front mounting make sure the pipes are at the bottom, if you can't do this then top mount. Is the basis of the video
Just found this video after RMAing my PC. It was noisy an overheated. When I get my pc back I'll doublecheck cooler orientation. Thanks for very informative video. 👍
I work in a winery. I deal with several different types of pumps on a daily basis. Including completely breaking them down for maintenance once in a while. One of the first things I teach newbies is how to get air out of the lines and away from the pump. Some pumps cannot be run dry or they damage the impeller, which is exactly what is going on here if the AIO pump is at the top of the loop. When I got my first AIO cooler on my gpu, it shocked me that there wasn't any info in the manual about the pump, where it is and how to best position it. For me it was obvious because gravity and flow of liquid are things I work with daily. I can see how somebody might not understand it, especially since it's all hidden inside hardware that isn't meant to be taken apart.
Yep I am one min in and your comment about gurgling hit me right in the heart. Turned my crap off and flipped the radiator. SMH, such an obvious mistake! Thank you for pointing that out.

Another PSA: Cavitation isn't happening in your CLCs/AIOs. The motors aren't that powerful, you'd need to go to industrial applications for that. Cavitation is when water vaporizes on the surface of an impeller, which isn't happening in these hobbyist-level motors. With cavitation, air isn't in the voids formed but water vapor is. With CLCs/AIOs, it's just air bubbles getting pulled through the loop (not cavitation).

So that is the best choice?
@@elfo7 yes that is the very best way you can do it !
@@elfo7 The key is to ensure that the pump is NOT at the top of the loop. Tubes going into the top of the radiator is fine as long as the actual pump is lower. This message gets a little lost in this video with a great deal of detail.
The goal is to avoid air in the pump and the way to ensure this is to apply physics - air will always move to the top of the loop.

Considering what case manufacturers seem to be doing with the front of cases I could totally see it lol. 2 120mm fans, with no where for the air to go because there's glass with RGB on top of it.
Just the rad end tanks would be awesome, great visual check for water flow and fluid levels.
This was incredibly informative and educated me on the science behind AIO water cooling so I could make more informed decisions with my build. Thank you very much!
Just gravity. Water flows downward.
fist of all hes kind of wrong with it cus back and top is the exost fans that blow hot air out ur pc now having ur radiator on top ur heating up the cooling as the hot air blow thro the radiator resson for front mounting cus front is the air intake ware it suck the cool air up and with radiator there now u got cool air blowing thro ur radiator cooling the liqued down inside alowing for cooler temp on cpu its phisics and commen sens
ikr, im thinking of going to liquid cooling, but still yet to find a case i want.
@RedEye Directive Gaming try corsair case like the the rgb 7000x rgb I think it's called come with icue fans 4 of them and corsair icue rgb box to control the rgb I like it or u can try 1 of there ether case like the 5000D I think it is
@RedEye Directive Gaming the corsair 7000x rgb u can use a 420mm radiator the biggest thay come in in a aio version
Always wondered if radiator orientations mattered, but all the other videos only talk about thermals, and not about what happens to the radiator and noise etc. So thanks!
Considering this, why do thermal coolers not make any trickling noise, and why does orientation not matter? they too have liquid / air inside.
@@Skelath What do you mean by thermal coolers?
@@Skelath Such a small volume of liquid that "changes" properties, from liquid to steam, then back again.. as it falls to the bottom of the heatpipe.
Additionally, the liquid is "moving" by gravity, and not a pump... giving no mechanical noise.
@@Mr1Tanker To add one more point to this, it's also moving via capillary action - i.e., it's not "dripping", and more flowing. As an example, when you turn the sink on and hold your finger in the water stream pointing down, when you move the tip of your finger, the water sticks to it and gets redirected. When the water is flowing like that, it doesn't make any noise - all the noise is from the aerator, or the stream hitting the basin of the sink.
@@Skelath because passive cooler have no mechanical pump to list the fluid in the heat pipes, it works purely off evaporation (I want to say convection, but I think that's technically incorrect). The only moving part(s) would be the fan(s) and that's a whole other discussion...
Edited to include that this TLDR is just a quick recap for those who have watched the whole video and have a full picture understanding of the reasons why and why not.
I STRONGLY encourage viewers to watch the whole video and the follow-up (th-cam.com/video/tU7D6y_QYcI/w-d-xo.html) and not to start panicking about their set-ups. Apologies to Gamers Nexus and everyone for any misinformation this comment might have caused.

Top-mounted radiator: Yes
Front-mounted radiator: make sure the tubes are coming out from below, not the top and make sure the pump is below the highest point of the radiator.
Bottom mounted radiator: don't. just don't

This is the first time I've seen a "STOP DOING" clickbait type titel that I actually was doing wrong. Shut down the pc* and flipped the radiator. And yes the boot up blub was removed, and no more gurgles.... And it even runs cooler, though that is very very likely to be mainly caused by the fact that while at it I removed the radiator's winter coat....
What's even worse, I work in oceanography and know my way around turbulent flow... I should have known, but never actually thought about how to do it, just mounted it and it (kinda worked).
*By shut down I mean tried swapping it hot, then decided I needed a bit more room and pulled the cords out of it.
I say don't feel bad. It's not your fault that case suppliers provide bad info and the product documentation isn't the best. Blame marketing for not making sure the info is well known enough. It's not your job to be thinking about PC parts, it's the people supplying them.
This is frustrating for me, mine is set up in a way that is not ideal although not the worst according to this video but the water lines on my Aio aren't long enough to install it any other way.
I had no idea this was even a factor and me and someone had a long talk about air in the lines when I was building it my opinion was that the air would be better at the top near the barbs ala nzxt config but they thought it would be better for them to be in the reservoir. Mine is mounted on my 2080 and I'm really curious to know how much of a difference it might make because I don't really have any complaints atm.
Really cool that you work in oceanography!
My uncle is the training office for oceanographers in the military. So salute to you!

I've been looking everywhere for the answers that literally only this video provides. I'm building with an AIO for the first time in two days. I did so much research and was convinced until this moment that tubes up vs tubes down didn't matter for front mounted radiators. I'm so relieved to have GN finally provide a definitive answer on this, yet pissed that AIO has been around for God knows how long and only now is there a correct answer floating around as to how you're supposed to mount your shit.
I'm in the same boat. Just got my Arctic freezer II (finally) and have been looking for such a guide as this to know the best way to install it. Once again GN to the rescue!!
Very good info indeed. So just to make it clear ... If you have a Corsair H100i Titanium RGB cooler (like i just build) .. mounting the radiator as Corsair shows in their mounting instructions for the 465 case in the front with the tubes at the top!!!.... The correct way would be to turn the radiator around with tubes down .. Is it still ok to have the tubes come out at the right side of the cpu block/pump so you still see the "Corsair logo" the right way ?? I'm amazed that even the companies building the things show you an incorrect mount in there mounting instructions. But hey if we botch the mounting up like they instruct us too they "maybe" sell more Aio's if the user don't switch to another brand the next time. I have had no issues with water gurgling for the week the machine has been running. The Corsair Aio and their LL fans arent the most silent around but its ok as long as you don't have a very demanding cpu that need higher rpm to keep cooled. I am currently hitting in the upper 60's degrees on my R7 3800X package when under 100% load (67 the highest I've had), while having no higher readings than 35 degrees from the Aio. I take that is the water temp it messeures ? These readings are with all 5 Fans in the system set to "Quiet" If I hit Extreme settings tey drop to around 30/60 degrees. But if the Aio will live longer, I'm gonna flip that radiator. the tubes should be long enough. I just wonder if they have made longer tubes on the H115i if you have to go all the way from the bottom of the case and up to the cpu, think the H100 would have a problem. But as these 3 Fan cases often have a psu shroud that covers 3/4 of the intake from the lower fan, noone in their right mind would place a 2 fan Aio in the bottom of the 3 front fans. Plus on the 465X case from Corsair I'd have to remove the HDD case to have enough clearance for an H115, why I saved a few bucks and went for the H100. Thanx for a good video Steve. You propably didn't have the time, but next time just to clear it all out for the buttheads or non english native viewers of us, show a few shots more of correct vs incorrect mounted tubing configs for both front, top and back mounts of the Aio's. As I see it the bottom mount would propably only be needed for those ultra compact cases where you just barely can mount the Aio at the bottom.
I thought only about air intake or exhaust & front/back fan mount, gamer nexus deserves big brain tutorial award.
@DispelTheMyth Steve answers that in the follow-up video. Orientation of tubes coming out of the pump makes no difference.
If you mount it at the front with tubes down, you'll have better cooling and noise levels
19:46 - I work in medical devices industry for 16 years now in R&D. Part of my job is testing of these devices in the silicone models of human blood vessels systems. In those 16 years I had to get rid of a lot of air bubbles :D Your video is great, however I only partially agree with the setup at 19:46. You created kind of U-shaped loop. The problem is that if by any chance during installation you trapped some air in the pump (even if the pump is lower than top of the radiator), there's NO WAY the air from the pump will travel down the loop toward the bottom of your 'U'. Air bubbles are gonna remain trapped in your pump.
So whats the solution? Give the pump a quick shake while holding the radiator above it right before installing the AIO?
Just turn the whole case over 😎
"Have you tried running your PC upside down?" should be the AIO manufacturer version of "Try turning it off and on again."
Or use an R-ATX configurable case like some of Be Quiet's Dark Base series... 😅
500IQ plays
i actually did that XD
the front of my case is at the bottom
omg i just turned my case over and my temps went to 30c to 26c but i still going to flip my radiator or maybe mount up top if that what he said worked too but thank for giving me that idea my case looks funny upside down right now tho lol.
This is the video that literally changed the shape of thousands of PCs since the day it was released and for the foreseeable future.
Hi. He's right and wrong.
As long as the cpu pump is lower than the highest point of the tubes on the rad, it's fine. Hot or warm coolant will rise faster as it's molecules are more spread, and it will have no issue travelling upward if the top of the raditior is higher than the pump, in a closed loop. Once the hot coolant is at the higher point on the radiator, gravity will let it fall down into the rad, and cool it as it fills with enough pressure to send the cooler liquid back up. Once running it won't matter. Only the initial cycle likley which has low load anyway. Provided there's no leaks and pressure is maintained, it should make almost no difference...
It won't kill your pump, in a healthy loop and properly filled one 🤷
No it didnt. People who are technically aware, knew this shit long ago.
@@Nick-GR Then people who weren’t as technically aware is now informed so yeah, this video still would have shaped thousands of PCs. Your comment is pretty irrelevant.

I built PCs and repaired them since the home PC was introduced, I started with Tech when the Atari game console was out and was the go to repairer in my neighborhood. I also tinkered with cars my whole life and know the orientation of a car radiator, the thing is I learned how these are installed correctly from working on cars. I am not a genius I just know the physics of how a pump for a radiator in a car works.
For almost a decade, I've used air coolers on all my builds until a few months ago where I cracked and bought a 360 AIO for my main rig. For AIO orientation, I asked many of my friends who use AIO, searched TH-cam, and google searched as if I was doing a project, but alas I did not find any answers. Until I remembered Steve mentioning in one of his videos not to mount AIOs like @17:56, but still no concrete answers. I ended up mounting it like @13:00 but with the tubes near the back instead. This is a great video since this is the only video that I've seen that actually answers how to properly orient AIOs.
I ended up mounting my AIO's rad to the top of the case simply because that seemed to cause the least stress on the hoses, had no idea I was saving it from bubbles and other issues too, now that I know how useful that is I'm defginitly planning it into future builds
I heard that throwaway comment on another vid too, changed orientation and saw an instant improvement in coolant temp. I've only had the aio installed a month or two incorrectly so fingers crossed it didn't cause too much damage.
@@CACOE_ You should be good! Unlikely it caused damage that fast unless it was really burning 24/7.
@@UNSCPILOT i have 2 computers with an aio one is on top and the other is on the rear exhaust simply because it's literally the only place on these 2 cases that could hold the radiator.
And this is why I always always tell people to NOT use AIOs unless they intend to do OCing and the majority will never OC and does it just because it makes their case "authentic pro gamer". You can't do much wrong with a fan - it's usually quieter, cheaper, easier to install, works on all cases (only need to take RAM / component clearance into account), you can't really fuck it up that it breaks and you have so many choices for fans + on a massive cooler, if the fan breaks you can replace it. If a AIO pump breaks .... not to mention potential leaks, installation issues, cost, noise level, your case potentially not working (which you always find out after you try to install it of course).
Honestly one of the most informative and easy to understand videos i've ever watched. I plan to upgrade to an O11D Mini SNOW and a DeepCool AIO and this information will be invaluable since it's my first AIO.
I'm looking to do this same setup. Did you end up top mounting.
From what I understood side mounting though less ideal is not bad either.

It wasn't 12am but I did too.
4 Years ago when i bought my first AIO the dude at the store told me to just put the radiator as high as possible. Told me to put it in the top with the fans exhausting the air through it. After this video I understand exactly why. Thanks random KTM employee :)
Good samaritan
the problem is the aio as exhaust.. because the hot air will go trough the radiator and is not cooled enough
good advice
@@clasch87 That is not a problem, its standard for a reason.
@@zachmullins9444 Steve literally said in this video that’s it’s not as cool to run as exhaust instead of intake.
Just bought my first water AIO and after reading around was starting to have doubts about installing it because of so many people complainign about gurgling and pump whine etc. I had all but decided to return it in favor of the "big ass noctua" that's proving so popular (and MUCH cheaper), however it seems it could well be they were all just mounted wrong.
@Thomas B LTT did a test and found air coolers beat most AIOs anyway
@@dumbodum the air cooler featured in the video wasn't a random air cooler but rather the best one noctua had to offer. More often than not AiOs beat air coolers
bought kraken 6 years ago and i’m using it wrong ?😂 still is quite and efficient. buy aio!😊
@Thomas B plus if the air cooler has 2 fans, its very unlikely both would fail at once, the other fan will probably be enough to keep it running
The noctua n15 is comparable to many 240 or 280 rads in terms of cooling, thermals and sound, based on GN charts from most recent best of video. It can’t compare to the 360 or 420 rads, but if you don’t need that much cooling, then that kind of air cooling is totally viable. GN tested the n15 with a i9 12th gen, so it was up to cooling that stock. I like the safety of air cooling - I personally prefer parts that don’t have even the potential to fail in a way that will damage other parts, but that might be my engineering background. I am thrilled aio are so so much more reliable than when they first came on the market tho.
Unfortunately, front-mounted, tubes-up is often the only way a particular liquid cooler will fit it a particular case, either because there aren't appropriate mounts anywhere else and the tubes are too short for tubes-down, or because there's an issue with clearance related to the motherboard or the RAM that prevents mounting it in the top of the case.
Yeah, that's a common issue, unfortunately. The good news is that it mostly causes noise and is less likely to cause long-term damage (but the noise may become annoying over time).
@@GamersNexus Yea when y'all showed Barb's at bottom it didn't look like a graphics card would be able to fit in there is that why it wasn't installed.
Can confirm that this is an issue with my Liquid Freezer 2 280. The tubes are too short for tubes-down but luckily GN below says it's just a noise issue for the most part and I honestly don't really hear anything from my AIO so I guess it'll be fine for now?
This is my problem. My GPU is in the way.

The problem I find is the tubing on these AIO coolers is nearly always too short to mount them properly with the tubing at the bottom of the radiator as described in this video. If the manufacturers would just make the tubing a bit longer this might actually be a possibility, but pretty much every build I've done that isn't top mounted has to be upside down due to the pitifully short length of tubing provided on these units.
Luckily all the ones I've used by coolermaster were long enough, love them
4 cases and I dont have one that could mount properly.

I've built maybe 13 or 15 cases in the past 2 years or so. And never had any issues. The inky issue I've had so far is actually with my personal build.

@@JhustineProvido to be honest i just moved my vertical because it simply had better cooling in my case. They have 5 year warrantys anyway
Yeah, I mounted mine like the AIO makers do it... I have a 360mm AIO that can only be mounted vertically on the front of the case so I can't top mount it and the tubes won't get around my 5700XT Red Devil to flip it in the front so I'm screwed.

The push from GamersNexus got case manufactures to bring back mesh cases, now we may see RGB tempered glass AIOs. AIOs may start looking like mini custom loops now. On a serious note, I really wanna see a case manufacture bring back side mounted fans. Come on now, you guys can bend glass. I don't see why you cant put a 200mm fan on a side panel.
+Germaine Breakenridge it won’t look that good,
Please 😍
A way to sneak in more rgb, so probably. Hopefully with very short warranties because folks will see the air pockets and think it's leaking.
@@GSXone why would you want side mounted fans though, they're a pain in the ass and disturb the airflow going front to back of the case
Yep. You must use the top of the radiator (I/O pipes below) as an air trap. I installed a vertical radiator, so the air trap was above the pump n block by about 3.5cm to ensure it gets no air gets into it too. It worked flawlessly. Very quiet, very efficient, faster on loads, and temps were the absolute best.
Because if the pump is too low, if there is any air is in the top of the radiator, the pump has to push water up OUT of the IN radiator to flow into the OUT radiator. To have gravity place an immediate resistance onto the pump is not optimal. I feel, even if you have a top mounted radiator, the pump too low will have to push water upwards into the IN radiator and rise up before it will come back out of the OUT radiator. Keeping the pump just below the air trap with as little of the res water above, in a 100ml system, will reduce static pressure on the pump by at least 90 grams even when the PC is off. But the pump and IO pipes MUST be below the air trap and the IN line to the pump n block on top above the pump n block OUT line as in the video^ .
I honestly never knew this, I always have mounted my AIo’s with the tubes coming out the top mounted at the front of the case! I always did this due to the manufacturers photos/ from seeing other you tubers do this, crazy how know one has mentioned this before
that's physics! GN has only explained it :)
Aren't the hoses too short anyway to put the tubes on the bottom in a front mount situation?
@@navithefairy depends on the AIO and the case, sometimes yes
@Erich Ly that's a nzxt design problem. They know it, they probably did it on purpose.
@Erich Ly If it's secured and it works, It's not a problem not to do it the "right" way
Glad you found a solution
The pump for almost any cooling device whether it be a pc or car should be below the highest level of liquid, this ensures that liquid is constantly being flowed through the pump due to height and gravity. Dry running pumps can cause many problems and eventually cavitate them.
Well put. I think 3 minutes of this video could have been omitted by just simply saying “make sure that the afferent line to the pump is being fed by a reservoir that definitely has no risk of air accumulation - being below the fluid-air level.”
in any way pump and temp will separate dissolved air. for avoid that, cool agent must be warmed max as well cooler itself and only in that condition it must become watertight

Similar story for me. I run a 7-year-old x61 that cooled an FX 8320 at 4.6ghz for years and now a Ryzen 3600 at 4.3ghz. Still doing fine but I would like another way to control the fan/pump speed other than using the CAM software. 😁

101 on how physics is annoying with liquid cooling, and how to and not to kill your water cooling loop/aio.
This mostly applies to AIOs.
In custom loops you generally have a reservoir/pump combo where the pump is always under the Res and will always be submerged.
I just flipped the whole case and realize that I'm not using an AIO
I flipped my house, and it seemed to fix the problem. Bong water, anyone?
Can someone tell me if mounting the water block (the part sitting on the CPU) upside down is a problem?
@@AAWT probably? If the air pocket forms at the side where the CPU contacts, conductivity will decrease. Although it might vary on the structure, Even a tiny air pocket on wrong place might be crucial as it would be a dominating factor of thermal resistance. On the other hand, high flow rate near the pump might prevent air from accumulating.
Doing research on my first build. Glad I saw this video before starting it. I was going to install the AIO exactly the way you said NOT to. Now that I know this I will make sure to install the radiator at the TOP of the case. Thank you so much for saving me from making a massive mistake right off the bat.
GN have been looking at Jays Twitter feed and after seen so many systems with bad AIO installs couldn't resist doing this video
I was thinking of going to an AIO (for the first time) to move away from my stock cooler that came with my 3600X after finding out that it wasn't keeping my CPU at temp levels I was happy with at idle. I have to admit, reading reviews of them on sites like Newegg, and Amazon really turned me off of the idea. Then I found this video, and it completely changed my mind. THANK YOU Gamers Nexus, for putting out quality content for people like me, who have no idea what they're doing with liquid cooling and want to dip their proverbial toe in with something simple like a prebuilt AIO. My new AIO is currently running soundlessly (except for the slight whir of the fans) at the top of my case and keeping my CPU MUCH cooler than the stock wraith was able to do, even with updated case airflow, and I credit this video for restoring my faith in the idea, seven months after it was published.

Every front mounted AIO I've ever seen has had the tubes at the top, I always thought it was a bad idea, and I always did tubes at the bottom myself, but I never knew if it actually mattered at all.
Then this video pops up in my feed randomly, 2 years after it was posted, and finally I'm validated lol.
It's not that it's a bad idea, very often mounting it tubes bottom will make it hard or impossible to mount longer gpus. As long as the pump is below the highest point of the loop it should be ok. The worst thing that can happen is some bubbling noise in a radiator. I am currently using be quiet! silent loop 2 mounted like that but it has a port for refilling and it comes with a bottle of coolant so if it ever starts to be noisy I will just refill it. It is suboptimal but there won't be any damage.
@@afgncap Thank you. This wouldn't be such an "embarrassing topic" to him if he'd have first considered what happens to the hoses in a bottom mounted 360mm radiator setup in order to get them past a 340mm long video card with a rollcage for a frame in order to get to the AIO pump. Or if he considered a problem like mine - where a dual SATA HDD cage is sitting close enough to where the tubes exit the radiator if bottom mounted that they have to be doubled back on themselves 10mm out from the fittings just to get over the cage. I'm going to go with "that would be a worse idea than any top hose mount".

So... a lot of us are pretty much screwed then.
I mean, if I mount my MasterLiquid ML240RS with the rad up front (tubes up), I'm basically introducing bubbles (and the gurgle noise, which happens but is not very common) into the top of the rad. I don't think I can mount it tubes down because of the GPU, but I'll try it tomorrow, and mounting at the top is possible, but I may not have the space to do push/pull the way I have it now.....
It's also rather infuriating to think that, even though I have considered this before, there are no directions on this on pretty much any manual. In fact, it lead me to believe there was some unknown system built in to let air bubbles escape.....
if they had longer hose it could work
I have the exact same problem, looks like going up top is the best option, but I know for a fact that push/pull would be imposible because of RAM clearance issues ( I tried it when I put my system together in the first place)
I had to put mine up top.
The instructions were garbage and I had no idea what to do because of it just being pictures and poorly made ones at that.
Hoses weren't even long enough to put them at the top of the front panel.
>So... a lot of us are pretty much screwed then.
Yea p-much
I'm running a Kraken x62 AIO in a fractalDesign Meshify C which barely has enough room to mount the radiator at the front if your graphics card is a long boy. Having the tubing at the top vs the bottom could be the difference in getting that radiator to fit and it's what I'm facing right now.
Can't mount the radiator up top cause then it conflicts with the motherboard.
I have a narrow micro atx case. It can't fit a decent air cooler because they're too tall. My only option for managing thermals with an overclock is water cooling but there's no option for top mount and my HDD tray blocks any hope of mounting the rad tubes-down. I'd may eventually get a new case but it is perfect for my desk size. There's zero noise aside from fans and my temps are fantastic, so is there really a problem here?
this made me double check that my closed loop system was installed properly, and I did indeed mount the tubing at the bottom :D You guys have really useful information.
Sadly most AIO's have short tubes and mounting them "correctly" isn't viable, specially with a big hardware piece that you didn't mention in the middle, the GPU. In my case for example if I mount the AIO like you say the tubes are stretched as far as they can go and they push against the GPU, putting a ton of strain on the PCI-E. I agree with the testing but most of the time that's not viable in a real use case. Maybe companies should make AIO's with longer tubes.

I'm several minutes in and I still have no idea which way is supposed to be the right one.
Mount inlet/outlet tubes at the bottom of the heat exchanger; top of pump mounted at least a couple cm below the top of the heat exchanger. Any air in the system should eventually collect and stay at the highest point of the loop, which ideally will be the 'tank' space at the other end of the heat exchanger from the inlet/outlet tubes.
If sideways, tubes down, if at bottom of case, don't, if top of case, orientation irrelevant

@@healman1000 phew. I top mounted on a whim and was right lol, mostly just to help move the exhaust upward.

For me, who works with pumps in the daily life in the oil field this is 101 basics. Quick google told me the pump in a AIO is a centrifugal pump. Shortly put, they have very bad vaccum lift and must therefore be primed.
What that means is, the tank should be placed higher than the pump, that makes gravity fill the suction side of the pump 100%. Simple rule, keep the low and everything else high.
Poorly primed pump increase chance of foam/caviatation. This causes noise, at high pressures it could cause damage (not very likely in an AIO).

3 years later, this is still the most informative video on liquid coolers and how to best mount them. There are many different types of liquid coolers, and the same solution will not apply for all of them. This video provides an in-depth explanation that helps people find the best orientation for their liquid cooler on their own.
After finding out about this, I'm surprised to see how many rigs have the pump/block as the highest point in the system because of how the case is designed. A ton of cases have the mobo mounts so high in relation to the radiator mounts that this problem would be unavoidable with pretty much all AIOs.
Same thought. Even with a massive case like TT P8 Core the motherboard is so close to the radiator/fans that assembly is difficult and risky sometimes.
@@mothambo Go with a Gigabyte C200. Super cool, classy case, and has TONS of space for mounting the cooler on top of the mother board. I'm having around 2-3 inch free space between my 56mm AIO and Ballistix RAMs(The closest thing to the AIO)

One of the first things I teach newbies is how to get air out of the lines and away from the pump. Some pumps cannot be run dry or they damage the impeller, which is exactly what is going on here if the AIO pump is at the top of the loop.
When I got my first AIO cooler on my gpu, it shocked me that there wasn't any info in the manual about the pump, where it is and how to best position it. For me it was obvious because gravity and flow of liquid are things I work with daily. I can see how somebody might not understand it, especially since it's all hidden inside hardware that isn't meant to be taken apart.
I flipped my rad tubes down. Idle temps are now so low that I use my case to store ice cream.
make sure the icecream is at the top of the loop and above the cone.
mine are uniform. It twirls around then a straight shot at the radiator. It works well mostly because the tubes are really flexible and rubber lol
That's vapochill cooled, not water-cooled (now I need to check if steve and the gang have played around with it)
What kind of ice cream😛
Yep I am one min in and your comment about gurgling hit me right in the heart. Turned my crap off and flipped the radiator. SMH, such an obvious mistake! Thank you for pointing that out.
