- I love Linus' videos, but he had very wrong conclusions on how airflow works in this video. This is not like my typical videos but I felt I had to get this out quickly.
It is not turbulence that is causing bad GPU temperatures, but bad fundamental case designs. We need a case design shift to something more like Fractal's Torrent case with real intake for the graphics card.

I agree that this is the best case design by far. - วิทยาศาสตร์และเทคโนโลยี
Great analysis. It's amazing how many "tech" people have no clue about aerodynamics. When I built my PC it was common knowledge that having a strong flow direction was superior to multiple fans jamming air into your case.
That's right.
Except cpus flow in a different direction than gpus
What ever happened to side intakes on cases? Everyone's too busy worrying about how everything looks instead of performance.
Exactly.
I know this is late as hell but, the case I have chokes the hell out of the gpu air. I have a cooler master Q300I, the mesh is already a hinder and the gpu will hit 90-93 within 10 seconds of playing a game. maybe I can get a hole in the acrylic side panel and add a small fan.
still rockin my 2009 HAF 932
Back in the day, a side intake was considered cool looking too. All these fortnight and sociopath-simulator f*****s and their RGB trash...
40mm fan or fans on the back as intake could be good, i got 2 noctuas mounted on the slotbrackets under my gpu.@@MrMarrok657
the problem with ATX right now is that the hottest workload for typical gaming pc's don't ever stress the CPU it's often the GPU that has to work 100%, this is made even worse with tempered glass side panels and the power supply shroud so really intel and AMD needs to work together to create a slightly modified reference architecture or case manufacturers standardising PCIE extension cables to create a layout that is actually designed for gaming workloads.
Yes I agree very much on this
This is the first good criticism I've ever heard of ATX. Interesting
Even if both are running 100%, you have a 140-watt CPU and a 370-watt GPU, it obviously needs triple the airflow as the CPU.
@@OTechnology lian li Lancool ll and lll Mesh have a metal door below the side glass panels that is full of holes (mesh) that allows the GPU to get air from the side.
It's already been solved. Just get a case with an open bottom intake, so the PSU is either at the front, top, or behind the mobo in a separate chamber.
On my H500P Mesh + 2080Ti FTW3 one of the main thing I noticed is that vertical mounting lowers GPU temp by about 6c under load. With standard mounting, this card is designed to intake air from the bottom fans and exhaust from the side. Unfortunately for most cases side exhaust is blocked by glass. Vertical mounting gives more room for the heat to be exhausted from the rear and top fans.
I miss the days we had side fans like in the Thermaltake Element S. Or the Enermax Chakra, which had a button that could flip the side fan from intake to exhaust.
Interesting
It’s basically the restriction at the back that forces the air downwards and then it gets sucked up by the GPU
I actually remember that in the past PSU’s were always mounted at the top of the case … in some case you might still see the cutout for the 80mm fan that used to be on the back of PSU’s … then they moved to bigger fans on the bottom side of the PSU’s … I believe there were some issues at that time where some PSU’s overheated because of the case design with the top mounted PSU’s
And that is when we started seeing bottom mounted PSU’s so they could get fresh air from underneath the case and the power cable would not have to run to the top of the case
And than some company’s came with the PSU shroud that basically hides the PSU and cables …
I actually like the approach that cases like the Enthoo Primo, O11D, HAF 700 Evo and some others have taken where The PSU is mounted behind the mainboard tray (or at least has its own compartment but doesn’t block off any bottom intake possibility’s)
Yes it makes these cases wider but it also allows for HDD’s, SSD’s and small controller units to be hidden away from the main chamber
I think this would result in a best of both worlds scenario and might be the best way to go for manufactures moving forward
AWESOME! Makes a lot of sense! And I really think you are right spot on! Really helped me out in my decision on my next new build. Would you say the Cooler Master NR200 is a good option as well?
Great insights, really good to watch this kind of videos before buying or planning to build a gaming setup. Thanks!
Got the Torrent Compact and added two fans at the bottom for intake and one in the back for exhaust. Running my 3080 beast at 65 max ;) and loving it. Smart case design matters.
Great video! As soon as I watched his video I thought it was weird. Something like Lian Li O11 Air (Mini) is the perfect solution, every part can get cold unrestricted air, even the PSU. On a Fractal Turrent the PSU gets recycled air from CPU/GPU.
Yea the O11 is a good case as well but speaking in terms of standard single compartment cases the Torrent is the best.
So does that mean if I use the standard configuration with PSU at the bottom, front fan intake, rear+top fan exhaust, it's better to keep the case negative pressure, so cool air can be suck into the case from the PCIe backplate or the bottom mesh even though there are no intake fans for the bottom area which is right beneath the GPU? In my setup there is only one intake fan in the front and 3 exhaust fans (2 for AIO on the top and 1 in the rear), all 12cm ones. There is an extra slot for intake fan in the front, and to keep the high negative pressure, I shouldn't install another one, right? Besides, since there are 2 slots for intake fans in the front, does it matter which one I use? I am guessing if the fan is in the higher position, the air coming from it is more likely to exit the case directly without circulating inside, faster airflow will cause lower pressure and then cool air will be suck into the case from the bottom; while if it's in the lower position, it will provide intake air for the GPU, but then create much more complicated turbulence and it becomes extremely hard to decide if it's beneficial or not without a simulation.
100% w you on the Torrent. It's a brilliant design, and I hope we see more like it. GPU thermals are really important for gaming.
to nzxt h510 users, do you recommend putting an aio? I wa planning on getting one cause I like its looks XD. Should I add front AIO or AK400(or any tower cooler than can also allow top and rear exhust)? thanks!
I did a test covering passive air inlets that do not have fans and the turbulence disappeared, when the air flow meets the incoming air from passive inlets they tend to collide and ruin the flow.
Lancool 2 Mesh does a great job of GPU cooling with a PSU shroud. Especially when you install fans on top of the shroud.
This just reminds me why I'm still using my 7 year old Corsair Air 740. Front 3x120 intake, bottom 2x140 intake, Top 2x140 exhaust, Back 1x140 exhaust, a 92mm Exhaust fan in the PSU compartment, and a 92mm Fan VHB taped to the HDD cage in the PSU compartment to keep air moving over the HDD's. As long as I can keep getting components that fit in my Air 740, I'm going to keep using it...
I saw my best thermals for GPU and VRM's with a side panel intake. The downside is that this cost me the view of a glass panel. If your all about performance definately go for a side panel fan.
Experienced this issue in my case with triple intake front fan and one exhaust at the back. I was able to resolve the issue by setting a different fan curve for the bottom front fan. Making it spin faster than the middle and top front fan prevents the GPU from recycling air because of the higher pressure from the bottom.
did your problem resolved even with solid front case? i also have same issue + quite big gpu that make it worse 😢
WOW! THANK YOU! That's so obvious when you talk about it yet I didn't think of it! I have a Corsair 4000D airflow case with two bequiet silent wings 3 fans mounted as front intake. After watching this video I switched them from top/middle to middle/bottom positions (the bottom fan blows into the psu shroud) and this alone dropped my gpu (RTX3090 FE) temperature from 74*c to 65*C in Unigine Heaven!!! That's just unbelievable.
PS CPU temps have climbed a few *C probably because the tower cooler now misses a fan blowing cool air directly onto it, guess I'll have to buy a third fan some day but this doesn't seem to be a problem for now - it's much easier to cool anyway.
Yep. You really need some direct airflow into the area where the GPU fans are intaking air.
Never getting rid of my Cooler Master HAF 932 case. One of the coolest temp cases in history even to this day.
bro ı have cooler master haf 912 case and using tower air cooling system can u tell me what should ı do about top fan is it must be giving air inside or outside please help me
I have my rear exhaust fan flipped to intake, all the pci slot covers off and the bigger cover that goes over them and my front 3 fans are exhausting. It’s dusty but it certainly doesn’t let anything build up. there is some recirculating from the gpu exhaust though but it cant be much with this much airflow
I just built a system in a Lian Li LanCool 205 Mesh case and it's interesting to me how cool it's running, despite using a single fan air cooler. I ran the TimeSpy stress test just last night. Even with some overclocking applied to the GPU, it only rose to 63 degrees at peak. The CPU rarely even rose above 50 degrees. The LanCool 205 Mesh is a far more open design and seems to promote far more airflow than the NZXT case used in the test. It really seemed like the system in the video suffered from a lack of airflow around the GPU in general. If I recall, the GPU didn't have much clearance between the edge of the card and the glass panel, which would only increase the severity of the airflow "dead zone" in the bottom of the case.
The components I used in my build are as follows:
ASUS ROG STRIX B550-F Gaming MoBo
Ryzen 5600X
ASUS TUF Gaming 3070
Seasonic Focus GX-750
G.Skill Trident Z (2x16GB 3200)
1TB NVME SSD
(Yes, I understand that these components do not use as much power or generate as much heat as those used in the test, however I do think it represents and interesting point of observation.)
What about cases that have mesh grill on the side to allow fresh air, and as well 2 fans below the GPU? Example Lian Li Lancool 2, does this solve the 'turbulence' problem?
He's saying the problem isn't turbulance, it is overpressure from too much air pushed in vs out. The mesh might work to allow more air to exit the case.
I wonder would the whole dynamic change if AIO was used for the cpu? That way the heat is blown out by the aio fan and there will be lesser hot air circulating. I also wonder is a 60,80 mm intake fan at the rear just just the gpu will help to get fresh air into the gap and reduce gpu temp
Proper fan size along with placement and varied speeds is what creates a case that flows well.
Don’t understand cases like Corsair where they have the three side fans that do nothing but disturb the airflow.
Front and bottom fans run slower while rear and top fans run faster keeps the cool fresh air moving as it should.
Most of the PWM fan hubs are useless as they run all the fans at the same RPM regardless of the fans CFM.
Worth bearing in mind that often the goal is positive pressure to _stop_ air being pulled in anywhere except through filtered intake fans (i.e. NOT though the PCI grille or any I/O panels). With a typical 2/3 front fan and single rear exhaust this does exactly what you say, results in very little air flow in the bottom/rear of the case around the GPU. In view of this, as an experiment I recently had a pair of 25mm deep honeycomb vane grilles printed for the front two fans of just such a compact ATX case which had the effect of dropping GPU temps by 5-6°C while raising CPU temp by about the same, because the straightened flow now easily reaches under the graphics card, which sheds more heat into the case so the CPU runs hotter. However, CPU cooling was never an issue and they both typically stay under 60°C (previously it was high 50's CPU and low/mid 60's GPU with both loaded).
Good shit Owen 🔥
Seems like anything above 360p is still processing right now
Yeah YT is busy but video still looks fine !
@@PaulJohn01 I figured I could still get the point across so I released it!
@@OTechnology Pictures + Audio = Success 👍😁
Having the aio radiator in front of the pc isn't ideal too as it would dump all the cpu heat into the case. Unless the pump is situated in the radiator you would want it to exit its air on top of the case. You cannot do that with the psu on top.
Whats actually weird is in all tests I've seen the H7 flow has worse cpu temps, but better GPU temps (while having a bottom psu) when compared to the Torrent.
I’ve built 7 PCs in the last 5 years, 2 for me rest for friends - builds from 1000 to 4000usd and I keep saying - manufacturers need to agree on changing so many things in PC building space! PCIe slots are bending cause of thickness of gpus, power cables are sticking out in front of the window panel - stull like that needs to change in upcoming years. Nvidia new 12pin power supply connector is nice but i still dont like its from side not from the back of gpu ;)
you pretty much need a full tower these days for modern GPUs anything else you are getting a bit sweaty with all those cables.
I tried putting front fans as exhaust, and top one as exhaust and bottom as intake and it was better.... but only in open case, with closed (glass) it was worse.
you could make the bottom psu + cover work, just embrace the "negative phenomenon" seen in this case. 2 exhaust fan on the front, nothing on the back, and (presumably better) solid tops for that straight wind tunnel flow. this way, you may have your solid front panel back (as long as the frame openings surrounding the fans are sealed)
Still not ideal because the PSU would be exhausting its hot air right below where the PCIE slots for GPU intake are.
@@OTechnology iya bener juga sih
Interesting, I have 3 front intakes, AIO 2 fans top exhaust, and 1 back exhaust.... I experimented adding un intake fan in the under de GPU, near te 2 front intakes, and boy, keeps the GPU massively cool, always leaving that space under the GPU to naturally exhaust the hot air through the mesh panels, its amazing what air pressure can do, keep in mind, every case is different, you need to experiment. Fan speed for each section is also something to consider.
I've built in a few different cases over the years, by far the best for thermal management, ease of build and with moderate flexibility has got to be Corsair's Carbide 540 Air, the twin chamber design means that the majority of cables and PSU are hidden, you retain the possibility of a 280mm top mounted radiator, in my experience better than a front mounted 360mm which dumps the heat back into the case rather than straight out the top. The GPU has vents below and to the rear. I get very good temps compared with builds of the same components. Case needs to breathe.
Finally. Somebody not saying that 'more fans is better'.
Pro tip: put an intake fan blowing into your open PCIe slots, difference of a few degrees for me!
You are exactly right 👍
I bet if you jam a cardboard on the top of the backplate of the GPU to kind of make it a separate compartment, then make the bottom front fan an exhaust, the GPU temp would go down too.
Another good case is actually an ITX case, the NR200, with the power supply having its own fresh air on the side. The GPU intake air from the bottom, the CPU can take air in from the mesh side (or the back, if you use the rear fan as intake), and you can exhaust the air out the top. This is the ideal situation with each component getting its own fresh air. There are other cases that use this design principle. Meshlicious is another one with very good temp for the components.
Yes I agree. Actually a lot of SFF ITX cases have this ideal independent airflow.
Have that case and love it. GPU fan curve turned up to use it as intake and a 240mm AIO as exhausted to the side, right above GPU. Since it's just gaming workloads, my temps are more than fine.
My case is 15 years old & has loads of room in comparison to these modern ones 2 fans in & 2 fans out with the PSU on the top out of the way.
Turn a top psu case upside down and you get a bottom psu but with the same layout as the fractal case.
Fractal Torrent to the rescue
So you're saying that we should have adopted BTX?
tiny exhaust fan under the gpu solves this issue
Ty bro, for make this harder..
Now im searching what turbelance mean😅
lama ga upload brother,
cut a hole into the side panel and put a fan there. wonder if the avg person can cut glass without breaking it
with the right tools...any person "can" cut glass clean...but, nearly no one use glass cutter because a small mistake can cost alot
Linus is not use to hot air flow, it's Canada! From someone down under.
that why i have 2x120mm fans in bottem front + 2x140mm aio fan on top and a 1x140mm an at the top back so far it work fine
also fans are not the only thing it about what kind of fans you use and at what speed
""older"" fans are design for two special functions air flow or air pressure, modern case fans are designed to deliver a mixture of both
then there is speed intake fan should be slower then fans at the back or top
but dont sets the fans that blow the air out not at maximum speed!
since especially with fans that are designed for pressure, as these block themselves at a certain speed and thus offer less air throughput
I have lial li o11d.. if my fans 6intake and 3 exhaust.. my gpu temps wil be 73degree.. then if my fans are 3intake and 6 exhaust my temps only 67degree.. meaning. The hot air trap inside my case.. my gpu is asus strix 3090.
No its more about where you place your intakes and exhausts for most cases. For an O11D the best config for GPU temps would be all bottom intakes and everything else exhaust like your example of 3 intake 6 exhaust because all the exhaust fans are pulling air away from the GPU as much as possible. But the CPU temp might suffer from sucking in hot GPU air if you have a water cooler. So personally I think the best compromise is all bottom intake and a side intake for the CPU water cooler and top and rear exhausts.
I don't see point of intake fans at all. If you have an appropriate amount of exhaust then equal intake won't bring any more fresh air into the case. All you have to do is direct the air that the exhausts are pulling through with intelligently placed vents and baffles.
Makes complete sense to me... I'm using Bequite Dark Base 900 Pro Rev.2 case fitted with 2 x 120mm Bequite Silent Wings 3 2200 RPM fans at the bottom of the case, they keep my GPU between 26 C no load to 56 C under full load with a positive upward air pressure. GPU cooling is becoming more critical with bigger more power hunger cards, keep cool and your GPU will last :)
so its pulling air from the psu upwards? Im trying to cool down my pc and im in a tropical country. I need to cool down my gpu thermals.
@@NectarGaming after watching this video, im thinking about flipping my front lowest/3rd fan to make it exhaust, to lower the pressure atleast in the bottom part, for my GPU and PSU to effectively pull air from behind.
@@MrClauried if you do that it will not provide cool air or any air to the GPU if you have bottom fans you should place it in a way it intakes air from bottom of the case
if only the torrent wasn't twice as expensive as every other case.
you pay double for double performance
you pay more to get something better...what do you expect?
What about bottom to top airflow?
I mean it would be the most logical because heat goes up... No?
in theory yes...but again...having such airflow as perfect as possible would require shifting most motherboard components vertically instead of a traditional horizontal build ( front to back air flow design )
the best vertical airflow you could have is only bottom and top fans, gpu mounted vertically and modded so it only pushes air upwards ( block bottom and side exhaust route )...and for cpu, an aio would generate as less turbulance as possible in the middle area while keeping it's warmth out the case
other than that...i'm not a hardware engineer but as for vertical airflow...i guess nothing could beat that...as long as air pressure stays positive ( more intake than outtake )
You can see smoke exit where you claim it’s coming in lmao
why do ppl in the tech space say Zen instead of Z. Like Zen390??
never heard that one before XD...idk who you watching but they're clearly not professionals
Until now, I still prefer Lancool 2 mesh for the extra area that's under the gpu have the ability to install 2 fans for gpu airflow
The torrent case literally is all mesh at the bottom.
i have an Antec flux series pc case. I have installed two 120mm fans above the psu cover. Air enters the psu space from the bottom of the front (i have 3 intake fans) and from the back panel which has a mesh grill. I began to use this method because my old r9 290 was an oven and i had a Nox case which had the option to put the fans above the psu. The r9 went from 85ºC to 70ºC. Check it out, mine is the dp 502 flux.
That is a good solution
Higher gpu temps were known to be an issue ever since basement power supplies and psu shrouds became a mainstream design. However it looks better than the old school designs with top psu and cables hanging down all over the place.
Also i don't think the industry puts too much focus on gpu airflow the way it does cpu airflow, as big gpu coolers are generally good enough to keep the gpu from throttling, and smaller gpus can just ramp up fan speed to noisy levels and the temps will be alright.
At the end of the day though, components don't really care if they run at 65 or 70. As long as it isnt throttling it isnt a problem.
New video from you. Long time.
Finally someone who doesn't just say "more fans, more fans!!". Doesn't the Series X have 1 exahust fan? Let's talk about fan shrouds too and why it's important to seal up the area around the fan.
The bottom-to-top airflow pattern is the best, especially with all of these new passthrough GPU heatsinks. I'm tired of all of these giant basement dwelling PC cases that have the graphics card crammed into a corner. Why does the basement have to be so huge, anyway? How many cables and HDDs are people cramming in there? Why can't the PSU be worthy of being showcased?
My second favorite airflow pattern that's becoming popular is the Lian-Li 011 Dynamic side exhaust style. If you are using a vertically mounted graphics card with a passthrough cooler, the hot air should exhaust directly out through the side vent. This is much better than a lot of cases that choke off vertically mounted graphics cards, especially sandwich form factor SFF cases. Stop choking the hottest component in your PC, people!
I'm an engineer and I completely agree with you

How anyone could take serious advice from an entertainment channel with a man wearing a pink hat inside is beyond me.
Well In reality if that all really does bother you you can just build a custom water loop that cools the graphics card properly
Yes but full watercooling is the minority in most computer builds.
@@OTechnology agreed.
high end solution require money...and not everyone want to spend 400$+ on a gpu water block + all watercooling equipment that is required to do so....remember...you gotta be ready to spend 1000$ for custom water cooling

My money is on the GPU power cables blocking flow.
Nope that has nothing to do with it. They're out of the way basically sticking to the glass panel.
@@OTechnology I don't agree, you know the cable is going all the way down towards the motherboard.
It is like 3 rods that are breaking the airflow, and turn into a turbulence wall restricting air to go towards the back I/o ports.
I would agree that the air flow is very restricted already, cause the fan is hitting the gpu from the side.
About 1/4 of the air is going down there but is getting blocked by 3 massive cable bundles.
You can't say it has nothing to do with airflow, the cables are literally there.
@@N0N0111 Nope turbulence again has nothing to do with it. A bit of cable with free space around it is not going to stop a fan's airflow. They are used to blow through heatsinks that are a much higher restriction without problems anyways. Again the cable is not in the way of the front fans airflow in the first place, you can see in how the smoke goes behind the cables in Linus' video.
@@OTechnology Okay fine we both are not experts, hope some expert on YT picks it up :)
@@N0N0111 Turbulence has literally nothing to do with it. It's the thermal capacity and dynamics of the case that suck. One roof mounted fan exhaust and one rear exhaust. That case would suit a 120'140mm Rad with also one exhaust fan to alllow for thermal circulation to begin with, not the honking air cooler that Linus used. Plus the two fans in the front would allow for balanced air pressure. This means that they GPU gets all the cool air it needs from the front and back and the case has enough capacity to move a lot more air in and out more efficiently.
Thermal dynamics is a very complicated science. But use a bit of common sense and more space means more capacity for air flow yes?
An AIO will allow for dual zone air flow. VRM's, RAM CPU cooling zone up top and the GPU getting all the air It can from back and front without it being parasiticaly being stolen from the air cooler. The case simply isn't designed for air cooling. It's a design which is utterly flawed but can be overcome with a 120/140mm AIO with a CPU and motherboard to suit where the AIO can be mounted ontop or the back exhaust and the exhaust fan also fitting in the top or back as well. That way you have thermal capacity and correct pressures from front to back and ALL components getting fresh clean air in and hot air exhausted at the same time all while minimising dust build up. The only issue left of the PSU shroud. You can overcome that with tin snips 😊. Or just accept the short comings of the case. There was more than enough breathing space for the GPU still using my example using Linus's example though. It comes down to knowing you thermal capacity and dynamics of your case and what WILL and WON'T be suitable for the case you buy.
This is a 120/140mm Rad and 3 120/140mm case. The motherboard should be a mid to low end board with nothing more than a I5 or 3600x. 750watt PSU inside. The ram spec should also not be super fast (anyway its not needed for this spec build as well) to avoid unnecessary heat soaking in the top of your case with no ventilation.) The rest needs to be be ssd, no mechanical hdds as again heat soak issues.
Saying all of that, It's a terrible case hands down and turbulence has nothing to do with thermal capacity or case dynamics it's just a byproduct of what Linus caused with that honking air cooler to begin with.
I personally use a full sized tower and AIO on my CPU and also AIO GPU 😂.
But I'm running everything at serious overclocks and all extremely high end from front to back plus Led's and capture card etc and a 1000watt PSU. My case is currently the Corsair 750D(High airflow), I'll be upgrading to the Corsair 7000D High airflow this year. Turbulence doesn't cause heat soak it just lowers cooling efficiency is all. Just always remember capacity and dynamics for case suitablity for building PCs. If it's high - enthusiast end bigger case is better but more cost and more fans. If it's a mid to low end build, mid tower to itx. An itx build for example I3, Ryzen APU, Nvidia 1050/1060 600watt PSU at most!
Mid build as mentioned with this case and only up to a 3060/3070 or 6600/6600xt GPU..
Build for your needs not what TH-camrs show you. Especially micro itx case with a 12900k and RTX3090 and 1000watt low profile PSU for heaven's sake!!!! It will melt over long use periods and shorten the life off all components by up to 80%!
You'll literally have your PC for six months before you need to replace almost everything with a brand new build.
I hope this covers both discussions you are both having sufficiently.
Kind regards,
CTT.
Haha lian li lancool go brrr.
In all serious ness my pc just blasts all air out. 600 watt's of system power draw? The only thing hot is my gpu backplate and radiator. Steady 62°c on my rtx 3070
Before 5:50 you claimed that turbulence isn't the reason that gpu gets hotter but after 5:50 you clearly shown air circulation process because of not having equal amount suction fun. Dude this also a kind of air turbulence 😉 where air is not stable for pressure difference because of frictions. This one of vital study field of fluid mechanics. Even though I'm doing my bachelor in EE, but I'm whole nerd on mechanical engineering since class 8 and having tons of knowledge of different sectors. Even tho my bachelor program also contain this semester Mechanical course on fluid machineries, turbines (steam and gas), ice, boilers and so on..
Yea no that is completely different. Pressure differences is not turbulent air.
Dude, had you ever have any fluid mechanics course in your bachelor? Or you're just claiming this out of your ideas?
@@KingKong-xp6so Lol you don't need to know fluid mechanics to figure out what's going on with that case airflow.
I don't even need to bring out the phenomena happening inside the case to call you out.. I'm just showing how you're wrong about an idea and claiming sh#t out of nothing..

@@OTechnology no offence but he did exactly the same thing with : Thermoelectric cooling, corsair's fan/case flow cfd argument, liquid metal in various devices, aircon cooled pc, fridge / freezer cooled pc and debunking myths on watercooling / radiator size / /stacking in every single case he made a quick and dirty, arguably wrong video, then corrected it, or added *expert opinions* or called in steve from gamer's nexus, or some other youtuber to make folloup pieces, custom hack hardware in his inhouse lab to try and prove some point or another. now once is a mistake, twice is a coincidence, what we have here is a psycopathic tendency over a career to mislead people into clicking on multiple videos to resolve a question or situation he instigated.
@@NeutronicalGaming True he did make a lot of wrong conclusions to flawed testing. Like how I also made a video on the water vs air cooling test that he made that was also broken.
What you and Linus are saying are both right I think. This because the air circulating inside the case on a system level (the case) is also called turbulance, I think. Don't know for facts exactly, but I think Linus might have been thinking so as well. You just get the fundamental reasons and mechanics quite well here I think and also helped me understand pc case airflow better. Haven't watched the full video of Linus so can't compare otherwise.
If you want to do a video on a product, and Gamers Nexus has already done a video on it, it is always going to be in your best interest to watch that video from Gamers Nexus before.
Linus talks a lot of crap without really knowing anything. Why trust a marketing funny guy about real tech issues? He's been exposed so many times (even the latest with GN) over the years, and people just give him a pass. Sad.
Simple solution: AIO in the top (140/120 mm) Same with the exhaust fan. 2 in 2 out right? Plus really crappy case to begin with 😂.
Basically it's a budget build case to begin with, not a high end build. All I'd put in there is a budget 3600x board and CPU. 120/140mm Rad and exhaust fan with a 3060 and 750 watt PSU. 2x front fans etc as well. It's not a case suitable for high end components at all!! And yes terribly designed. NZXT need to steer away from case design and keep doing what they're doing best still. And that's NOT case design 😂.
At the end of the day, just don't buy NZXT cases
Case designs are shit now.
no , linus is TWO fucking jokes.
you said it yourself your not a air specialist LOL, The main issue why temp increases in the gpu is due to that TOWER COOLER try to swap it with an AIO then you can kiss goodbye for GPU high temp.. The reason why adding more noctua fan keep reducing GPU temp is due to the fact that Noctua Fan Runs really fast and very silent and pulls more Air "The very reason their #1 premium Fan" The system has a dual Noctua Fan Tower Heatsink vs a weak smaller GPU Fan basically (Stock Fan > GPU Fan BUT More GPU Fan a lot > then GPU fan) as a result CPU Fan takes mostly all the AIR from the intake Fans but when switched to noctua front fan then they pull air outside of the case more efficiently and push air faster inside the case where the CPU FAN pull this faster than the GPU. Then About Turbulence it does affect Case Air Flow why??? in Linus video incomming AIR gets slit up instead of going into a Straight lane at the lower Fan which causes the going up and some going down (LOOK if theres a 3rd front Case fan below that then there will be no GPU thermal increase "they said it in the video its because the case is small and ITS CORRECT there is NOT ENOUGH CLEARANCE FOR AIR Below the GPU and not Enough Front Fan that should BLOW AIR BELO THE GPU" Turbulence did affect If you read BOOKS or Research about AIR and AIRFLO etc. a air pressure in a straight line is more efficient versus a air that takes a curves "Example the very reason why MESH case gets better airflow is due to the fact that Fans pull AIR in a Straight Lane then Solid Panel Case gets POOR airflow due to the fact they pull Air from the side which means the AIR needs DO A 90 DEGREE CURVE" This LTT particular set up there's three parts that causes the rise in GPU temp #1 Case #2 CPU Tower Heatsink #3 Noctua Fans for #1 can be fix with a case that can support 3 Front intake AKA Larger Case or a M-atax Case that support 3 Fans not 2 #2 can be fix by replacing with an AIO to gave GPU all air that it needs #3 going for slightly lower performance Fans I.E. stock fan rather than noctua fans BUT will increase CPU temp. Then the things you are wrong thats why i can't finished this video itself #1 the Stock Fan set up is not in negative air pressure "i can answer did since i just watch the video before this one" its in a nuetral airflow which mean its BALANCE = cool air going hot air gets up and the proof that its nuetral is GPU pulls air on the pci vents IF ITS NEGATIVE Then SMOKE SHOULD NOT GO IN = your MISTAKE #1, NOW #2 dumb reason by you = NOT ADDING TOP EXHAUST??? can you see the Top Front Fan most of the 2nd FRONT FAN gets pulled by the CPU FAN and that is also gets pulled by the REAR exhaust Fan pulling the HOT air that gets pulled out by the CPU heatsink? the top Fan will only pull little BIT of AIR WORST THAN The GPU due to = Poor Clearance = a Straight lane AIRFLOW Config is present and the air flow is strong.... #3 With the Noctua Fan added GPU no Longer gets cool air from the PCI vents which means you are CORRECT its now in POSSITIVE AIRFLOW but its Feels like you HATE the IDEA OF POSSTIVE AIRFLOW due to the GPU TEMP? The Hell WE ALL WANT POSSITIVE PREASURE that means LESS CLEANING MAINTENACE for DUST issue. #4 the GPU Airflow is Circulating taking cool air blowing out hot air and now taking hot air?? YOUR DUMB you said it its on POSSITIVE FLOW those HOT AIR will gets blown by COOL AIR going outside the CASE ... WANT PROOF? You already said it in the video THERE IS NOW SMOKE GOING OUT OF THE VENTS which is really really really GOOD TBH. Linus is correct and wrong the wrong one here dude you said it yourself you don't know anything about AIR or something. This Scenario is very NORMAL when you are using a TOWER Cooler the smaller case you Use the Bigger the CPU tower cooler and the More Fan it has the more the GPU will heat up thats Fan Fact#1, IF you Truly Want steady Flow of Air then GET AN AIO It will Fix GPU vs CPU temp one affecting one another BUT a Case that has smaller GPU Clearance will always be a CASE AIR FLOW Issue for the GPU.
Hi. I am planning on getting this case because it is my dream case while not knowing the issues. Do you have any recommendation?
Which setup do you think is good? Feel free to suggest.
(currently planned setups)
Setup 1:
1 rear exhaust
1 top exhaust
2x120mm aio front intake
or
Setup 2:
1 rear exhaust
1 top exhaust
1 air cooler (deepcool ak400)
2 front intakes (or any suggestion if I should add)
I need your help. I really what this case so even tho its quite hot, I just need help to make the best of it. Thanks!
Nice work. Linus is insufferable in so many ways, not the least of which are how the treats people, puts money above factual testing, and his voice lol.
More fans don't make the cp hotter. How they are positioned is what is important. More fans that are positioned properly will make it run cooler.
Linus is wrong about everything.
I just wrote a comment to this effect on his video (just now) before I saw you had just posted this video 😂! He's a total @$*/$"@! (word I can't use on TH-cam 😂)
Your conclusion is correct, but your reasoning is flawed.
Menunggu versi indonya
Linus is obnoxious AF, that's why he's popular on TH-cam
This makes me not want to get a H510 case for my next build
