***** I can agree with you on that, being a Brit myself. Shame so many brits are complete chavs an dont know the difference between a house or alcohol :/
Cooling is a function of the following factors: the delta of the two thermal systems, the available thermal exchange area, the convection dynamics, and the conductivity of the thermal exchange mediums. You basically isolated three of the four variables. The Silver Arrow Extreme has almost the same surface area as the H100i, which is why they performed so closely. The H100i did have an advantage in that the entire surface area had first run air running over it, where as the second radiator of the Silver Arrow Extreme was using preheated air from the first radiator (thus lowering the localized delta, thus lowering the exchange efficiency). If it wasn't for the stacked nature of the Silver Arrow Extreme I think you would have seen even closer numbers. In the end, cooling optimization is about being sensitive to the four controlling factors mentioned above and optimizing for each, and not over optimizing one at the cost of the others. Which is demonstrated in most push pull configurations, where the flow of a single fan has already reached optimal, and then you add a second fan, and you can't go past optimal. If however the single fan hadn't achieved optimal, a gain would be realized by adding the second fan, but not pass optimal. So if you're 90% there with the first fan, the second fan will only realize that 10% difference. Honestly, I'm curious what the numbers would have been if you had run the Silver Arrow Extreme with only the center fan. I wonder if the back pressure from the two radiators would have been significant enough to severely affect performance, or if there would have only been a few degree shift.
As an engineer, I'd like to confirm Linus' temperature correction as accurate. I'd also like to thank him for correcting to 519R as per the 1970 U.S. standard atmosphere.
"Go ask a physics professor, that's how it works, it's not something I want to debate about" That's approximately how it works, but certainly not to within 0.1C like you're recording it to. Change in temperature is highly dependent on initial temperature for multiple reasons, specific heat varies with temperature, thermal conductivity, radiation, air flow. It's certainly accurate to within 1C to just treat it as a scaling, but not within 0.1C. Though there are much more major problems with how you're measuring this anyway, there's absolutely no reason to display it to 0.1C.
BlueCosmology yeah Linus can be a cocky bitch sometimes about stuff. I bet in high school he got punched in the face a lot. Or maybe not cause its Canada and they are very nice there.
I had a Seagate Barricuda 2tb die on me after two years of home use. I was bitter, and after a few months of crappy 5400 speed hdd, I upgraded to an Intel ssd with a hitachi ultrastar 2tb *both chosen for reliability). The hitachi ultrastar is the loudest hard drive I have ever had. I never cared about noise, but WOW, this is a loud drive. Now I get it.
Carat and Karat is a weight and purity - A carat is a unit of weight for diamonds and other gemstones. One carat equals 200 milligrams (0.200 grams). There are 453 grams in a pound (1,000 grams to a kilogram). Therefore, if your fiancee weighs 170 pounds, you have a 385,050-carat fiancee! A karat, when used with gold, is a unit of purity-- 24-karat gold is pure gold, but usually you mix gold with a metal like copper or silver to make jewelry (because pure gold is too soft). Each karat indicates 1/24th of the whole. So if a piece of jewelry is made of metal that is 18 parts gold and 6 parts copper, that is 18-karat gold.
With gold, "karat" refers to purity, not weight. 24 karat gold is pure gold, 14 karat gold is 14 parts gold and 10 parts alloy (usually copper, zinc, and silver). "Carat" on the other hand, is weight. One carat is about 0.2 grams.
Wow...I'm glad I stumpled upon this video. Although its content wasn't what I was looking for, i'm still glad I watched this. This video gave me a whole new appreciation for Linus and the whole channel and media group. They have come leaps and bounds in just the past few years here. Like this is back near his start when he is still in his own garage filming his own stuff! There's no one else! lol Anyways point being, this was eye opening (in a good way) and gave me as a viewer a new found respect and I suppose admiration for what they have done in just the past few years. It's impressive.
We now have one more type of cooling to add to the mix: Peltier Cooling. And it's working in conjunction with water or air cooling, or you'd need a huuuuge heatsink. What about using Peltier (ThermoElectric cooler) connected directly to the heat-pipe of a laptop (or through soldering a heat-pipe extension for bringing heat the heat closer to the fan exhaust) to lower the temps for any CPU-intensive or GPU-intensive task? It might bring an old laptop to more decent performance, although at the cost of more energy usage. I mean, you would need to connect it to the source through something that can help you better control how much power you give it (just like you'd control a fan's speed), because of how much power it uses on mas power and because of the risk of condensation if the temperature is low enough or the cold side is not isolated well from the rest of the system. Sure, you could fit one of those between the heatsink and CPU/GPU, but you'd need to have it on all the time, to not have it effectively act as an insulator.
as linus says he did it with a single fan speed, and there is software to ramp up the fans as it get hotter, so you can turn them up, to bring the temp down. He was going for consistency. I'm sure if he turned the fans up it would cool better, however that was not a variable in the setup.
great stuff, thanks. you could have tested theses on separate time intervals or use two different systems with identical set-up. As the temperature multiplier affects your validity. make sure all parameters are the same before you start taking readings.
ambient is 10 c and the processor still got to 70 c ?? wow try this in Australia now with the ambient room temps hovering around 25 to 30 c . cook the pc for sure.
Inseperable Generation That is strange you have the same processor and fan I do lol~ But my processor is the same way, I have trouble getting it above 50C even when my room is 80F ( which is like 26C )
Excalibur is for amateurs. I want to see him put that 80mm rad back on there with a pair of Vantec Tornados @ max RPM. I had an Alpha PAL8045 on an old overclocked Athlon CPU and a Tornado mounted on top. I kept it wired to a potentiometer mounted on the front of the case and when it was at full speed, CPU temps didn't flinch going from idle to 100% load.
someone's asking about alcohol for cleaning thermal-paste. alcohol basically doesn't help at all. it's pretty much the same as just rubbing with a papertowel. What does take thermal paste off is lighter-fluid. You don't even need to rub in some cases... just put a drop of lighter fluid, and tip the surface so that the paste/fluid mixture runs off the way you want.
+gagongflip389 exactly. If it's not making noise that means something stopped working. Just like with children if they get quiet that's when you start worrying. Plus I can't go to sleep if my computer/fan/fans is not running. Silence is deafening.
Nailed it Linus! Quiet computing comment of yours is überlogical :) I have common user friends telling me "ooh look i have 6 fans in my case". Actual feeling is like gaming with a tractor. Yet them cant achieve the frequencies i get (trust me, i'm an electrical engineer)
+Cloverskull For us old timers who have been building PC's from way back, ours have always sounded like 10hp vacuums with the end of the hose clogged up. Even the loudest fan on the market today is pretty quiet to me.
***** Office computer? How dare that idiot call a well-made gaming computer with an elegant, minimalist-designed Fractal Design case an office computer? On second thought, I would want to work for a company that gives its employees computers like that for working in the office.
+Cameron St.Laurent Yeah, I hate the "gamer" styled....anything. To me the gaudy plastic crap and random LED's everywhere just looks cheap and corny as hell. I love the simplicity and cleanness of my NZXT S340. I don't have water cooling or optical drives so it's pretty much perfect for me. I did put an LED strip in the top that's controllable by a remote, but that's the only light (I have it set to slowly fade between colors). I'm really digging the Noctua NH-U12S CPU cooler as well. It, along with a straight blade Noctua exhaust fan and two NZXT 140mm intakes on the front keeps everything very cool and quiet.
I think the Corsair H105 or h100i are a good way to go with, their both around the same price, its dual radiator but if you dont want to overclock the h80 would be great aswell, and note that the pump is always the loudest of the AiO watercooling solutions
Well a push pull set up doesn't really make a difference in alout of setups linus made a video about that awhile back. But it's a thick single radiator so it will perform a tiny bit better
It was a joke on his use of the word "scientificist". Scientificist isnt an actual word... I didn't think it would be so difficult to spot the joke, my bad.
tbh no thats kind of true for bikes though generally the quieter they are the more powerful they are. I don't know if that's just because I live in England and all cars are quiet it's bikes that are loud, and the weak once are the loudest
...deeper thought: The whole reason for needing a cooler in the first place is "heat density". Fast processor chips (the _real_ parts inside) are tiny yet they generate copious amounts of waste heat in that small space. Moving that concentrated heat somewhere else, REAL fast, is priority #1. So in the end, this is about fin surface area (final heat rejection area), and if you are looking for the lowest temp possible when running at design load, the best cooler will be the one with the greatest area available to dump heat. That's why that one with the wide radiator and two side-by-side fans performs so well...
LarlemMagic I WEAR HEADPHONES! BUT WHEN THEIR IS NO SOUND IN THEM IT DOESN'T BLOCK THE FAN NOISE SO IT KINDA KILLS THOSE SILENT MOMENTS IN GAMES AND MOVIES- THATS WHY I'M SHOUTING..
Tbh Stock will do, although spending a tiny bit on a CPU cooler can make a difference. Also if you are thinking you might not now, it doesn't mean you won't a bit later on. It could benefit getting a better one than stock just incase. Also depends on the sorta build quality you want to go for, cos the extra expenses do eventually add up.
Wait, are you talking about overclocking your CPU? NO, it won't do. I have a 4790k with stock cpu cooler and it can easily reach 80c with the SLIGHTEST of overclocks. I have 5 noctuas in my case so there's enough airflow, it's just that the stock cooler isn't meant for overclocking.
Hi Linus. You never did the pull versus push/pull comparison for the h100i that you said you would do at 1:03-1:25. You only did it for the h80i, and for that cooler, it proved the opposite of what you expected. I know this video is (currentYear - 2012) years old now .. but maybe post a followup where you actually show the thing that you said you would?

Amazing tips Master Linus, Could I ask, have you evr been asked to "chekup" or assist in "cooling" for High-end performance (Gamming) Pcs over in "tropical" countries? - I live in México and in the lower, "Caribean Side" of it, so Humidity and "heat" here is really high. I'd love to knwo how to "combat" this situation (Without moving to another more, "mediterranian" weathered place). :D Thanks in advance for reading this.
i "think" that "maybe" you "shouldn't" put "quotes" around "every" other "word" in your "post" even if you are in a "tropical" area that is "warmer". the quotes like that are for when you are saying something sort of smart a**. like if you lived in a freezing climate and said oh i experience so much "heat" in Antarctica, referring to the cold as heat. looks like you are saying you live in a place that everyone doesnt consider "tropical" and that you may not actually be on the "Caribbean side" and that there isn't actually "heat" there, and that you are not actually going to try to "combat" the problem.
What do you guys think, is there any difference (other than minor) between corsairs line of all-in-one liquid coolers or NZXT Kraken? In terms of performance, that is.
I have recently ordered NZXT Kraken X61 and I have cancelled as many are complaining about it's pump producing rattling noise. So go for Corsair. They seem trust worthy. I am planning to get the H110i GT or GTX when it gets released. Some review say H110i is silent. Have a good day. ☺
Malovon When i was deciding on closed loop water cooling or air cooling I read an article where someone was talking about the pros and cons of both (and custom loop water cooling) and they were saying that Corsair will replace their part that broke and also any parts that it took out as well. I don't know how true this is, but considering this person spoke from experience I went with H100i for my cpu cooling.
Longmir Teron The Corsair 110i GT has gotten great reviews, however if you want silence neither comes with particularly good fans, i recently got a corsair H105 and i already had the fans i wanted purchased cause the stocks are WAY too loud. Buy a couple of noctua NF-A14 or silverstone SP141s (the latter are more reasonably priced) and you get amazing performance at great sounds level. I basically did that but with a H105 cause performance was very similar and i already had good quality 120mm fans. I think you made a good decision since the new H110 is basically a 3rd gen product (they skipped the hypothetical 110i) and Corsair has been tweeking it for a decade to optimize their design. Just...get good fans ;)
There's a HUGE difference between pull and push. I went from pull to push and got 4C off of CPU temps. push/pull is best ofcourse, but bit too much, no need for it really, push pull would only get maybe 1C off, but makes a lot more noise. I have top mounted H100 in push, works better than back mounted push/pull.
***** The 212X is the upgraded version that hasn't reached proliferation yet. Fan aside, the difference lies with the aluminum fins. They have X-shaped perforations around the heatpipes. These perforations have a two-fold purpose: the first is to help direct some of the airflow around behind the heatpipes to stop "heat pockets" from forming, the second is to allow for better a better type of airflow.
Minizw3rg yeah, its pretty powerful though so it does vibrate a hell of a lot. I can just leave my fans on lowest setting and have it silent and still very cool temps
TheSuaveITguys Well I don't think a small fan in front of your case will do much. I even turned mine off to make my pc even quieter than it already is and don't feel a difference.
Biggest issue I find with water cooling solutions is the radiators with there smaller fins tend to clog up with dust much faster then standard air coolers do. I know mine tends to need to be cleaned monthly but I live in a dustier environment because of a cat, dog and wood stove.
Bah at least your humility and honesty shows. There are young boys who only spend a couple of months watching videos and reading articles and all of a sudden they think they're certified experts, going around giving awful advice and getting worked up over false data. I've spent YEARS around PCs, obsessed over tech, even worked for TigerDirect for a while and I'm still learning new things...
I don't really understand it either. I have very basic knowledge about computer tech stuff. I do however enjoy gaming very much whether it be PC or console or handheld and I get geeked out when hardware or software are showcased.
Rythmatical if you watch a lot of Linuses older videos or well " newer " to this video since its 2012, he teaches everything you have to know extremely well, i've been watching them for about 4 or 5 months now and i already know enough stuff i could tell how most of the stuff works
I think simplicity should factor in when considering a CPU cooler. I have stuck with air cooling for years because, while it's definitely inferior to water cooling, you can still achieve an acceptable result without the worry of physically having water/antifreeze/silicone oil which can leak/evaporate inside your computer. Every liquid system leaks a tiny amount, no matter how good the seal, and one of my friends had a rig die on him after a few years because he had one of these sealed (water not replaceable) water cooling systems which formed a significant enough air bubble that his CPU overheated and died (which is admittedly somewhat impressive because the thermal throttling mechanism inside the CPU must have also failed at the same time).
+mrtannzr FTW 2gb dual cooler, runs good just has loud fans, and it locks at 39% min runs good, just a little lod and that might be a result of having a lot of case fans and a 750W PSU
For you people that use those all-in-one water cooling solutions, make them the exhaust, and the rest of the fans intake (pressure optimized fans). Though some will have so hot internal air that its better to have radiator as intake, then make all others (except the harddrive cooling fans) the exhaust. That 0.02 bar pressure difference does help since its 2-3 watt fans.
The Noctua just reminded me of something. Can anyone tell me if I'm gaining any cooling performance by putting fans in series? i.e. 2 fans stuck up against each other so they're both blowing in the same direction. I had a spare fan so I put two like that as my case exhaust fan. But I'm not sure if it helps or whether they just disrupt each other's flow. The huge Noctua heatsink having a fan in the middle as well as on the side makes me hope it does help.
Those two fans should be designed to work in series, maybe like in a turbine. Otherwise you will have a higher failure rate (because of an increased RPM, physics thing.) without any better performance (also a physics thing). Let me give you a better source than me, because you won't be the last one to ask this question; Google. :)
Linus - for corsair cooler, did you make the fans blow intake? I overclocked my 3770k (costa rica made) to 4.6Ghz and cool it by H80i. The temp was 55C while load (game like Modor, Watchdogs, GTA V at least 1hr played!) The closed loop liquid cooler will be required less fan than Silver Arrow passive cooler. You know most of server use air cool to blow heat outside,,it's EXACTLY Silver Arrow wants the user to do, use more fan to blow heat out since it is AIR cool!
Seriously Linus - there IS an excuse for loud computers. 1) I wear headphones and 2) I can't blow $40 per fan like you OH WAIT you got yours for free. Stop lecturing about crap like this. I hate it.
You're pretty much listening to enthusiast cooling. It's like the usual enthusiast telling you to buy a better videocard/better CPU because there is no excuse for low performance. Stop being butthurt
***** Yeah but it isn't a big deal, Linus has his own standards and quiet fans are not only limited to Noctua (you can buy better priced Cougar Vortex/Deepcool AF with just nearly the same performance)
I like having several 200+ CFM fans on my computer case. Might be bit of an overkill but having them run at low speeds doesn't really generate too much noise. Booting up your PC at lan parties is always a nice spectacle.
@12:27, your comment should be emphasized *that under normal cooling, the 'free' Intel-included cpu fan is nearly as good as the $100. H100i from corsair.* Once guys buy these products they tend to hype them beyond all reason. Linus, thx for this comparo. We really need more tests of this quality to de-bunk the wild claims.
Well.. I "liked" this video because... Well.. It's a good video that shows every "practical" thing you'll need to know about these types of coolers. As alway great job Linus.
About the comparison on the back of Corsair's box, it is somewhat accurate because my i7-4790k came with a cooler and it literally DOES fail because on full load with a CPU stress test, the processor always ends up throttling and operates at 99 degrees pegged. I'm fairly certain I don't run any applications that requires the cpu to run at 100% at all times, but if I do end up rendering something like a video or 3D model, it'd be great to not have the temperatures pegged at 99 degrees.
I've purchased a Corsair Hyper 212 a few months ago, and it works significantly better than the stock cooler, but if I were to overclock this system, there is still absolutely no way that the cpu will remain stable. Its quite upsetting that I have the ability to overclock a CPU but restricted due to thermal reasons. Given, I'm new to all of this, and my system isn't even thermally optimized.
I recently saw some Peltier Thermo-Electric Cooler projects, and I am curious Linus, would a TEC setup (which produces ice on the CPU side) with a water cooler on the hot side allow for a higher overclock than a traditional water cooler? The hot side with the water cooler should be very hot, but since the processor remains cold, the heat should be easily dispersed by a water cooler. Just an idea if you wanted to tackle the project, I would be interested to see the max TEC overclock for an i7-4790K vs a traditional water cooler.
Hi Linus, I hate to burst your bubble, but just correcting the temps by adding a correction factor doesn't exactly work. The heat transfer in the radiator (for water cooling) or tower (air cooling) will be dependent on the temperature differential between the medium being cooled and ambient. So at low ambient you'll have higher heat transfer. This means that if you make that adjustment there's no compensating factor for the difference in actual heat transferred during the cooling activity. However, if all you're talking about is 11C-ish, it shouldn't make THAT much difference. Just thought you'd like to know. :)
Absolutely love this video Linus! Possible suggestion (even though I know you probably have years worth of videos to complete) is a comparison of an H100i (or the best equivalent out-of-the-box cooler at the time) VS. say.. a custom loop of your choice. I know the price difference would be substantial, but it would be nice to know the temp. differences between out-of-the-box and custom insanity :)
Actually a carat is a measure of purity, not weight. I dont think the two thermal compounds you referenced have such a dramatic difference in purity or it would be drastically more expensive gram for gram. They probably labeled them to make it seem like there is a performance difference when there probably isnt much if any.
Some years later, could you do a small turbine - jet engine fan test, slightly extreme airflow would be interesting to see if that pulls away heat or just the air around.
I built a rig with a FX-9590, 16GB of DDR3 1866 and a single 2GB graphics by AMD. Plus I have two DVD drives, four WD Black HDD's and two SSD's by Corsair. I decided to go air cooling because I'm the old-school type of builder. I don't like the idea of having liquid inside my case. From MY personal experience, a case must be closed if you're using fans. For a very simple, physical reason: airflow. We all know that hot air is thinner than cold air and goes up (watch hot air balloons and you will see). Having front fans blowing in at the bottom and rear fans blowing out at the top will create a perfect airflow system as the air comes in cold, gets hot, goes up and comes out at the back. With an open case, this flow simply doesn't happen. I also picked pretty normal fans. They are mostly 12's and to cool the CPU I have the mighty CM Hyper 212 Evo, with a second fan creating a push'n'pull system. This CPU is known for eating power and frying eggs but you know what? My CPU rarely goes over 60 degrees, even when I'm gaming. I'm running it at 5gHz and I haven't had a single problem. Without any CPU management, simply running the OS and some random softwares, on Windows I get about 30 degrees. On Linux, I get about 25 degrees. It's not that quiet, I'll give you that. But it's cheaper than the liquid cooling and I have some awesome headphones that are noise-cancelling and I can't hear a thing. The wife needs to poke me when she has something to say. A few fans wouldn't interfere with the system's usability or performance. And fans look way cooler than pumps.
I only have some questions regarding your test results. First of all, did you take into consideration the thermal inertia of the cooling liquid? How long into the test did you take the final measurements for the temperatures? Another factor is the formula that you used to calculate or compensate the room temperature. Just adding the temperature difference to 20 degrees is not quite correct. All facts taken into consideration, a different type of air cooler, mainly an all copper one could have had better results than the water cooler due to the fact that there is only one direct exchange of energy when, in the case of the water cooler you have two, both of wich are subject to faults in thermal conductivity.
Because of the number of variables, you will never get the same numbers he did. This is just to show relative performance, not actual performance. So it doesn't matter. All we need to know is what is better.
"If you haven't seen my video about the fans........frigin awesome" this why i subscribe-along with all the useful info he gives us- he's fucking hilarious
I tried replacing the stock fans on the H80i with the dual fans from the Cooler Master V4 GTS. Works surprisingly well and noiseless at the same time. Previously, with the stock fans the CPU temperature approximately 40~42 deg with normal computer usage. After installation, the temperature is around 37~38 deg. *Edit: It is around 27~29 deg idle*. I used Corsair Link for the temperature reference. My CPU is the i5-4670. Sound levels have reduced considerably as well. I used a simple app, Decibel 10th to measure. With the stock fans I was getting around 67+ dB but with the replacement fans I was getting around 47+ dB with normal computer usage. I measured the sound with the iPhone about 10cm away from the computer for both measurements.
I get why the same fan was used in all the tests, but it feels a bit off to use an air cooler meant for 140mm fans & then downgrade it to 120mm fans. Those fans aren't even large enough to reach the outermost heat pipes. It might almost be better to compare the silver arrow to an H110 (or the never equivalent), & just pick fans from one or the other to rig up a mounting for comparison. The real moral of the story though is that 120mm radiator closed loop coolers are a waste of money.
I like how the stock H100i at load with HIGHER ambient air temperatures outperforms the H100i with lower ambient temps and the NF-12 fans that he pushes for so much, because it looks like the stock fans outperform his recommended fans
What you just said is retarded. The major limiting factor of overclocking, temperature, isn't limited by the higher temperature of lower performance. You are a GD genius! Haha. Shut your mouth.
James Porras Please stop being stupid. If you've ever had a half descent CPU cooler you would know that after a certain OC your processor will be unstable regardless of the temps. There is a limit to the amount of voltage you can throw at these things. I'm guessing you use the stock cooler and make dumb assumptions on videos like these.

Cooling is a function of the following factors: the delta of the two thermal systems, the available thermal exchange area, the convection dynamics, and the conductivity of the thermal exchange mediums. You basically isolated three of the four variables. The Silver Arrow Extreme has almost the same surface area as the H100i, which is why they performed so closely. The H100i did have an advantage in that the entire surface area had first run air running over it, where as the second radiator of the Silver Arrow Extreme was using preheated air from the first radiator (thus lowering the localized delta, thus lowering the exchange efficiency). If it wasn't for the stacked nature of the Silver Arrow Extreme I think you would have seen even closer numbers. In the end, cooling optimization is about being sensitive to the four controlling factors mentioned above and optimizing for each, and not over optimizing one at the cost of the others. Which is demonstrated in most push pull configurations, where the flow of a single fan has already reached optimal, and then you add a second fan, and you can't go past optimal. If however the single fan hadn't achieved optimal, a gain would be realized by adding the second fan, but not pass optimal. So if you're 90% there with the first fan, the second fan will only realize that 10% difference.
Honestly, I'm curious what the numbers would have been if you had run the Silver Arrow Extreme with only the center fan. I wonder if the back pressure from the two radiators would have been significant enough to severely affect performance, or if there would have only been a few degree shift.

"Go ask a physics professor, that's how it works, it's not something I want to debate about"
That's approximately how it works, but certainly not to within 0.1C like you're recording it to. Change in temperature is highly dependent on initial temperature for multiple reasons, specific heat varies with temperature, thermal conductivity, radiation, air flow. It's certainly accurate to within 1C to just treat it as a scaling, but not within 0.1C. Though there are much more major problems with how you're measuring this anyway, there's absolutely no reason to display it to 0.1C.

Bullshit, my Xbox is super quiet.
Because I never use it :D

+Bramble Star1234 Exacly what i Though "Ohhh". Just clicked show more comments to find it, unless I would have commented it I guess. :D
I had a Seagate Barricuda 2tb die on me after two years of home use. I was bitter, and after a few months of crappy 5400 speed hdd, I upgraded to an Intel ssd with a hitachi ultrastar 2tb *both chosen for reliability). The hitachi ultrastar is the loudest hard drive I have ever had. I never cared about noise, but WOW, this is a loud drive. Now I get it.
the fan on top wasn't even moving when he was showing how quite it was
Maybe it's the fan stop function
You're a really cool dude, Linus. By the way, I love your profile picture. Very Steve Jobs-esque! ;)
I want my case to roar like the T-Rex from Jurassic Park.
Lol.
go on micro center and look for the loudest case fans
+David Rook that was funny dood
+David Rock This just made me lose it lmao
+David Rook I take off the side of my PC case and use a regular 2 foot box fan! gotta wear earplugs when gaming!
Why you need a silent gaming PC? Just wear headphones of course!
Carat and Karat is a weight and purity - A carat is a unit of weight for diamonds and other gemstones. One carat equals 200 milligrams (0.200 grams). There are 453 grams in a pound (1,000 grams to a kilogram). Therefore, if your fiancee weighs 170 pounds, you have a 385,050-carat fiancee!
A karat, when used with gold, is a unit of purity-- 24-karat gold is pure gold, but usually you mix gold with a metal like copper or silver to make jewelry (because pure gold is too soft). Each karat indicates 1/24th of the whole. So if a piece of jewelry is made of metal that is 18 parts gold and 6 parts copper, that is 18-karat gold.
Well it's"diamond" cooling paste, hence the weight.
just go buy an xbox if you want a loud gaming rig" Shots fireddd
With gold, "karat" refers to purity, not weight. 24 karat gold is pure gold, 14 karat gold is 14 parts gold and 10 parts alloy (usually copper, zinc, and silver). "Carat" on the other hand, is weight. One carat is about 0.2 grams.
I lol'd at "get an Xbox". Mine is the original 2005 model, and it sounds like it's just about ready to take off.
"Why don't you just buy an xbox while you're at it."

Wow...I'm glad I stumpled upon this video. Although its content wasn't what I was looking for, i'm still glad I watched this. This video gave me a whole new appreciation for Linus and the whole channel and media group. They have come leaps and bounds in just the past few years here. Like this is back near his start when he is still in his own garage filming his own stuff! There's no one else! lol Anyways point being, this was eye opening (in a good way) and gave me as a viewer a new found respect and I suppose admiration for what they have done in just the past few years. It's impressive.
**gag** That intro though.
+fireclaw316
With those beating eyes I was just like ".......Okie......"

"oops, ferodian slip there"
X'D
The intro is so classic. And the filming to is so nostalgic.
do you think they could make some that don't look ugly? I doubt shit brown plastic and rubber is any quieter than any other color...
For people going for poop brown pc look
that cpu cooler blows so much it should work in a Thai massage parlour
We now have one more type of cooling to add to the mix: Peltier Cooling. And it's working in conjunction with water or air cooling, or you'd need a huuuuge heatsink.
What about using Peltier (ThermoElectric cooler) connected directly to the heat-pipe of a laptop (or through soldering a heat-pipe extension for bringing heat the heat closer to the fan exhaust) to lower the temps for any CPU-intensive or GPU-intensive task? It might bring an old laptop to more decent performance, although at the cost of more energy usage.
I mean, you would need to connect it to the source through something that can help you better control how much power you give it (just like you'd control a fan's speed), because of how much power it uses on mas power and because of the risk of condensation if the temperature is low enough or the cold side is not isolated well from the rest of the system.
Sure, you could fit one of those between the heatsink and CPU/GPU, but you'd need to have it on all the time, to not have it effectively act as an insulator.
I was thinking to run a motherboard inside a freezer
Enjoy your condensation
Jason MIlls got a dehumidifier on mine teehee
haha have fun ruining your motherboard hahahahhaa
Look up "water chiller" That's the closes cpu fridges get :p
In all honestly, it's basically a fridge compressor.
LMAO, you are a fool man, and I'm loving it:)
I know you overclockers would disagree, but I think anything above 60C is unacceptable ;p
liquid nitrogen?
Water Cooling
as linus says he did it with a single fan speed, and there is software to ramp up the fans as it get hotter, so you can turn them up, to bring the temp down. He was going for consistency. I'm sure if he turned the fans up it would cool better, however that was not a variable in the setup.
anything above 65 C on an AMD FX will cause problems, but on an Intel it is perfectly fine, their threshold goes all the way up to 90 i think.
ThatMessyAsianDude yea the intell i know has a thermal cut out of 100c but that is still pretty hight, i would want to take it over 75c
great stuff, thanks. you could have tested theses on separate time intervals or use two different systems with identical set-up. As the temperature multiplier affects your validity. make sure all parameters are the same before you start taking readings.
ambient is 10 c and the processor still got to 70 c ?? wow try this in Australia now with the ambient room temps hovering around 25 to 30 c . cook the pc for sure.
Yeah but look on the bright side. You can cook a nice juicy steak while playing!
Inseperable Generation That is strange you have the same processor and fan I do lol~
But my processor is the same way, I have trouble getting it above 50C even when my room is 80F ( which is like 26C )
Haha, silence is the key says Linus. I'd love for him to do a review of the Cooler Master Excalibur 120mm fans just so I could see his reaction.
Excalibur is for amateurs. I want to see him put that 80mm rad back on there with a pair of Vantec Tornados @ max RPM.
I had an Alpha PAL8045 on an old overclocked Athlon CPU and a Tornado mounted on top. I kept it wired to a potentiometer mounted on the front of the case and when it was at full speed, CPU temps didn't flinch going from idle to 100% load.
someone's asking about alcohol for cleaning thermal-paste. alcohol basically doesn't help at all. it's pretty much the same as just rubbing with a papertowel. What does take thermal paste off is lighter-fluid. You don't even need to rub in some cases... just put a drop of lighter fluid, and tip the surface so that the paste/fluid mixture runs off the way you want.
I want mine to roar like a dragon so silence is not my goal. lol....
+gagongflip389 same
Yep.
If it's not blowing papers off your desk you're not doing it right!
+gagongflip389 exactly. If it's not making noise that means something stopped working. Just like with children if they get quiet that's when you start worrying. Plus I can't go to sleep if my computer/fan/fans is not running. Silence is deafening.
+gagongflip389 I have never cared about silence. My PC could sound like a wind turbine for all I care.
+gagongflip389 I have a button on my GT72 that makes the fans go crazy, it never needs them that high but it shows people my laptop is a beast!
Nailed it Linus! Quiet computing comment of yours is überlogical :)
I have common user friends telling me "ooh look i have 6 fans in my case". Actual feeling is like gaming with a tractor.
Yet them cant achieve the frequencies i get (trust me, i'm an electrical engineer)
"That there's no excuse for them being loud." My pc has 6 1900rpm Scythes. It's pretty much louder than my vacuum cleaner.
+Cloverskull For us old timers who have been building PC's from way back, ours have always sounded like 10hp vacuums with the end of the hose clogged up. Even the loudest fan on the market today is pretty quiet to me.
+Dale Smith Try delta fans at full speed.
Not only are these quiet but they have no stupid, annoying LEDs on them.
***** Office computer? How dare that idiot call a well-made gaming computer with an elegant, minimalist-designed Fractal Design case an office computer?
On second thought, I would want to work for a company that gives its employees computers like that for working in the office.
***** The gamer aesthetic is ugly. Also, fractal design cases are way nicer than what offices tend to use.
+Cameron St.Laurent Yeah, I hate the "gamer" styled....anything. To me the gaudy plastic crap and random LED's everywhere just looks cheap and corny as hell. I love the simplicity and cleanness of my NZXT S340. I don't have water cooling or optical drives so it's pretty much perfect for me. I did put an LED strip in the top that's controllable by a remote, but that's the only light (I have it set to slowly fade between colors). I'm really digging the Noctua NH-U12S CPU cooler as well. It, along with a straight blade Noctua exhaust fan and two NZXT 140mm intakes on the front keeps everything very cool and quiet.
Josh Taylor What if they didn't use plastic? What if they used things like polished and painted metal or other things that are higher in quality?
+asdfghjkl It would be an improvement but if the styling is cheesy the material won't matter. I think simplicity can be quite elegant.
More of this! Excellent.
Updated & mainstream coolers {AC's & AIO's} tested on different mainstream CPU's & Cases.
Thanks.
Those are cool but the colors!!!!
UUUGGGGHH!!!!
Daniel Shalev I like the green!
ikr i want my pc look badass but like c'mon what the fuck are those colors?!
Makes perfect sense to spend 100's on a nice tempered glass case only to install the worlds ugliest fans.
This may be stupid but can you use the noctua NF F12 as a case fan in a non water cooled build?
You can but its a pressure optimized fan, its not optimized for better airflow.
thanks. ive decided to run a water cooler and OC my 3770k which cooler do you recomend
I think the Corsair H105 or h100i are a good way to go with, their both around the same price, its dual radiator but if you dont want to overclock the h80 would be great aswell, and note that the pump is always the loudest of the AiO watercooling solutions
I was looking at the h80 and only overclocking to the turbo of 3.9 maybe a little more but I will look at the 100 and 105
Justin Beyer and with the double radiator of the h105 or 100 you are able to let the RPM of the fans decrease => more cooling while lower fan
noise
You have certainly come a long way, Linus. Good job, good sir.
Would a H80i keep a non-overclocked 8350 under 70C?
yes it would your looking at ~65c at a 4.5 ghz overclock so there ya go
*****
awesome, how would it perform if it were in a push and pull setup?
Well a push pull set up doesn't really make a difference in alout of setups linus made a video about that awhile back. But it's a thick single radiator so it will perform a tiny bit better
Cool thnx
If only this was more scientificist. I demand things to be done as scientificist as possible.
+Ricky St. Louis Its linus not Einstein
It was a joke on his use of the word "scientificist". Scientificist isnt an actual word... I didn't think it would be so difficult to spot the joke, my bad.
+Ricky St. Louis the joke was very easy to spot and was pretty funny, 8BallManiax is just plain old dumb

+8BallManiax get busted being stupid, go straight to insults about homosexuality to really remove all doubt lol
Glad to see the air cooler bread to get some love.
A high end air cooler almost always costs less then a high end liquid cooler.
*Proud NH-14 user*
has anyone just plumbed a a/c hose into it?
I think there are videos. It's actually not a bad idea. Keeps shit nice and cool.
condensation becomes a problem
true
just ac ur pc a little hotter than ur house u derp
loud PC is like loud car, if it does WRRUUUUM you know it has power :^)
I attach whistles to my fans so the whistles go "Whoo!" so I comfortably know I'm under load.
I want you to say that after seeing my old pc.
+Phi6er it would be the engine, radiator or turbo... transmissions don't make that noise
Like those cars that go WRUMMMM but only going 10miles an hour right?
tbh no thats kind of true for bikes though generally the quieter they are the more powerful they are. I don't know if that's just because I live in England and all cars are quiet it's bikes that are loud, and the weak once are the loudest
...deeper thought: The whole reason for needing a cooler in the first place is "heat density". Fast processor chips (the _real_ parts inside) are tiny yet they generate copious amounts of waste heat in that small space. Moving that concentrated heat somewhere else, REAL fast, is priority #1. So in the end, this is about fin surface area (final heat rejection area), and if you are looking for the lowest temp possible when running at design load, the best cooler will be the one with the greatest area available to dump heat. That's why that one with the wide radiator and two side-by-side fans performs so well...
Wear headphones, save yourself 100$ by not caring about volume.
LarlemMagic I WEAR HEADPHONES! BUT WHEN THEIR IS NO SOUND IN THEM IT DOESN'T BLOCK THE FAN NOISE SO IT KINDA KILLS THOSE SILENT MOMENTS IN GAMES AND MOVIES- THATS WHY I'M SHOUTING..
I'm not gonna overclock and I don't care much about noise.
Do I need any of these stuff or will the stock heatsink do?
Stock heatsink and fan will be far more than enough as long as you have like 2 fans in your case.
Tbh Stock will do, although spending a tiny bit on a CPU cooler can make a difference. Also if you are thinking you might not now, it doesn't mean you won't a bit later on. It could benefit getting a better one than stock just incase. Also depends on the sorta build quality you want to go for, cos the extra expenses do eventually add up.
Dubzahh pL I basically just said that. Your comment was not needed at all.
Wait, are you talking about overclocking your CPU? NO, it won't do. I have a 4790k with stock cpu cooler and it can easily reach 80c with the SLIGHTEST of overclocks. I have 5 noctuas in my case so there's enough airflow, it's just that the stock cooler isn't meant for overclocking.
iTooob He said he's _not_ going to overclock.
Hi Linus. You never did the pull versus push/pull comparison for the h100i that you said you would do at 1:03-1:25. You only did it for the h80i, and for that cooler, it proved the opposite of what you expected. I know this video is (currentYear - 2012) years old now .. but maybe post a followup where you actually show the thing that you said you would?
NON GENUINE WINDOWS!?! IM CALLING MICROSOFT

EVERYTHING should be free.... :D
Essentially when you want to charge for something you want others NOT to have IT, literally excluding them. That´s why society needs to change double-quick.
PS: Yes, mine is genuine, alright. :D Still think it should be free though.
I'm using fake windows too, what the big deal about it
A few person using fake OS won't change their profit too
Whoa why do these nice fans have to have such a... shitty colour scheme?
Agreed
Form should follow function, if you don't like them that's fine. More fans for me :D
Light gray + strong graphite wouldn't hurt them though... :/
Edit: They do make exact colour schemes i described but technology wise backward in comparison to the shitty/skinnish series.
They do make that color as well. Check out the Redux series.
because noctua don't give a shit
You should do another one of these considering that its been almost 2 years and many more stuff has come out.

Amazing tips Master Linus, Could I ask, have you evr been asked to "chekup" or assist in "cooling" for High-end performance (Gamming) Pcs over in "tropical" countries? - I live in México and in the lower, "Caribean Side" of it, so Humidity and "heat" here is really high. I'd love to knwo how to "combat" this situation (Without moving to another more, "mediterranian" weathered place). :D Thanks in advance for reading this.
i "think" that "maybe" you "shouldn't" put "quotes" around "every" other "word" in your "post" even if you are in a "tropical" area that is "warmer". the quotes like that are for when you are saying something sort of smart a**. like if you lived in a freezing climate and said oh i experience so much "heat" in Antarctica, referring to the cold as heat. looks like you are saying you live in a place that everyone doesnt consider "tropical" and that you may not actually be on the "Caribbean side" and that there isn't actually "heat" there, and that you are not actually going to try to "combat" the problem.
What do you guys think, is there any difference (other than minor) between corsairs line of all-in-one liquid coolers or NZXT Kraken? In terms of performance, that is.
I have recently ordered NZXT Kraken X61 and I have cancelled as many are complaining about it's pump producing rattling noise. So go for Corsair. They seem trust worthy. I am planning to get the H110i GT or GTX when it gets released. Some review say H110i is silent. Have a good day. ☺
Malovon When i was deciding on closed loop water cooling or air cooling I read an article where someone was talking about the pros and cons of both (and custom loop water cooling) and they were saying that Corsair will replace their part that broke and also any parts that it took out as well. I don't know how true this is, but considering this person spoke from experience I went with H100i for my cpu cooling.
Longmir Teron The Corsair 110i GT has gotten great reviews, however if you want silence neither comes with particularly good fans, i recently got a corsair H105 and i already had the fans i wanted purchased cause the stocks are WAY too loud. Buy a couple of noctua NF-A14 or silverstone SP141s (the latter are more reasonably priced) and you get amazing performance at great sounds level. I basically did that but with a H105 cause performance was very similar and i already had good quality 120mm fans. I think you made a good decision since the new H110 is basically a 3rd gen product (they skipped the hypothetical 110i) and Corsair has been tweeking it for a decade to optimize their design. Just...get good fans ;)
+LadyAtlantaTbilisi good choice
the best cooling is obviously liquid nitrogen or liquid helium lol
Put your gaming PC in space, and just play games from your Shield.
just throw a bit of ice in it when it get a lil toasty.
I just put icepacks on top of my PC.
I just sit in my basement room. Where i live because i'm sensitive to heat and my pc is too.
LIQUID HYDROGEN M8 or SOLID FUCKIN HELIUM (which is almost absolute 0)
There's a HUGE difference between pull and push. I went from pull to push and got 4C off of CPU temps.
push/pull is best ofcourse, but bit too much, no need for it really, push pull would only get maybe 1C off, but makes a lot more noise.
I have top mounted H100 in push, works better than back mounted push/pull.
cooler master 212 evo is the best bang for bucks
***** The 212X is the upgraded version that hasn't reached proliferation yet. Fan aside, the difference lies with the aluminum fins. They have X-shaped perforations around the heatpipes. These perforations have a two-fold purpose: the first is to help direct some of the airflow around behind the heatpipes to stop "heat pockets" from forming, the second is to allow for better a better type of airflow.
ahahah he changed so much from this time to now!
He maybe look like a nerd, but he did put a lot effort and make Linus grow
We need more nerds in this world
Still a very useful video after almost 8 years!
i used cable ties to hold a small fan on the front of my pc for no reason... it's loud
Probably because of the vibrations.
Minizw3rg yeah, its pretty powerful though so it does vibrate a hell of a lot. I can just leave my fans on lowest setting and have it silent and still very cool temps
TheSuaveITguys Well I don't think a small fan in front of your case will do much. I even turned mine off to make my pc even quieter than it already is and don't feel a difference.
Minizw3rg i know but I like it there because it was a brilliant reminder that I need more screws for spares
but linus... im you're best fan...
Biggest issue I find with water cooling solutions is the radiators with there smaller fins tend to clog up with dust much faster then standard air coolers do. I know mine tends to need to be cleaned monthly but I live in a dustier environment because of a cat, dog and wood stove.
Whos watching in 2017
My head hurts, I know nothing about this computer tech type stuff...
You can learn it and this channel is a great place to start.
Bah at least your humility and honesty shows.
There are young boys who only spend a couple of months watching videos and reading articles and all of a sudden they think they're certified experts, going around giving awful advice and getting worked up over false data.
I've spent YEARS around PCs, obsessed over tech, even worked for TigerDirect for a while and I'm still learning new things...
I don't really understand it either. I have very basic knowledge about computer tech stuff. I do however enjoy gaming very much whether it be PC or console or handheld and I get geeked out when hardware or software are showcased.
Learning isn't too hard if you want to. Lots of good resources.
Rythmatical if you watch a lot of Linuses older videos or well " newer " to this video since its 2012, he teaches everything you have to know extremely well, i've been watching them for about 4 or 5 months now and i already know enough stuff i could tell how most of the stuff works
I think simplicity should factor in when considering a CPU cooler. I have stuck with air cooling for years because, while it's definitely inferior to water cooling, you can still achieve an acceptable result without the worry of physically having water/antifreeze/silicone oil which can leak/evaporate inside your computer. Every liquid system leaks a tiny amount, no matter how good the seal, and one of my friends had a rig die on him after a few years because he had one of these sealed (water not replaceable) water cooling systems which formed a significant enough air bubble that his CPU overheated and died (which is admittedly somewhat impressive because the thermal throttling mechanism inside the CPU must have also failed at the same time).
the comments. they are fixed.
about time, they really messed it up with that idea
what if i own a loud ass gtx 750 ftw?
+nprguyplayz turn up your speakers
my 750 is ultra quiet....then again maybe it's my headphones. :D
+mrtannzr oh I use my Logitech G930's when gaming but when I'm laying in bed and switch over to my stereo I can hear it
nprguyplayz is your gtx a reference card? Mine is evga, not to mention it's just a plain 750, no ti or FTW.
+mrtannzr FTW 2gb dual cooler, runs good just has loud fans, and it locks at 39% min runs good, just a little lod and that might be a result of having a lot of case fans and a 750W PSU
For you people that use those all-in-one water cooling solutions, make them the exhaust, and the rest of the fans intake (pressure optimized fans). Though some will have so hot internal air that its better to have radiator as intake, then make all others (except the harddrive cooling fans) the exhaust. That 0.02 bar pressure difference does help since its 2-3 watt fans.
The Noctua just reminded me of something. Can anyone tell me if I'm gaining any cooling performance by putting fans in series? i.e. 2 fans stuck up against each other so they're both blowing in the same direction. I had a spare fan so I put two like that as my case exhaust fan. But I'm not sure if it helps or whether they just disrupt each other's flow.
The huge Noctua heatsink having a fan in the middle as well as on the side makes me hope it does help.
Those two fans should be designed to work in series, maybe like in a turbine. Otherwise you will have a higher failure rate (because of an increased RPM, physics thing.) without any better performance (also a physics thing).
Let me give you a better source than me, because you won't be the last one to ask this question; Google. :)
Wait, what do you mean increased RPM? I don't see why that would be any higher.
Oh right, I see what you mean. Although I find it surprising that a fan would fail due to LESS resistance.
5:36 lol
Linus - for corsair cooler, did you make the fans blow intake? I overclocked my 3770k (costa rica made) to 4.6Ghz and cool it by H80i. The temp was 55C while load (game like Modor, Watchdogs, GTA V at least 1hr played!)
The closed loop liquid cooler will be required less fan than Silver Arrow passive cooler. You know most of server use air cool to blow heat outside,,it's EXACTLY Silver Arrow wants the user to do, use more fan to blow heat out since it is AIR cool!
Seriously Linus - there IS an excuse for loud computers. 1) I wear headphones and 2) I can't blow $40 per fan like you OH WAIT you got yours for free. Stop lecturing about crap like this. I hate it.
Why invest in fancy cooling? BECAUSE WE WANT LOW TEMPS, NOT LOW NOISE! God damn you were stupid back in the day.
You're pretty much listening to enthusiast cooling. It's like the usual enthusiast telling you to buy a better videocard/better CPU because there is no excuse for low performance. Stop being butthurt
Not butthurt. Annoyed.
***** Yeah but it isn't a big deal, Linus has his own standards and quiet fans are not only limited to Noctua (you can buy better priced Cougar Vortex/Deepcool AF with just nearly the same performance)
Dont forget the EK Vardar, closest to Noctua in quality, Performance, and noise level. And they are cheaper . . .
why don't you just get an xbox while you're at it lolololol
Because they suck.
I like having several 200+ CFM fans on my computer case. Might be bit of an overkill but having them run at low speeds doesn't really generate too much noise. Booting up your PC at lan parties is always a nice spectacle.
@12:27, your comment should be emphasized *that under normal cooling, the 'free' Intel-included cpu fan is nearly as good as the $100. H100i from corsair.* Once guys buy these products they tend to hype them beyond all reason. Linus, thx for this comparo. We really need more tests of this quality to de-bunk the wild claims.
Got this reccomended 8 years later, miss 2012.
same
Well.. I "liked" this video because... Well.. It's a good video that shows every "practical" thing you'll need to know about these types of coolers. As alway great job Linus.
About the comparison on the back of Corsair's box, it is somewhat accurate because my i7-4790k came with a cooler and it literally DOES fail because on full load with a CPU stress test, the processor always ends up throttling and operates at 99 degrees pegged. I'm fairly certain I don't run any applications that requires the cpu to run at 100% at all times, but if I do end up rendering something like a video or 3D model, it'd be great to not have the temperatures pegged at 99 degrees.
I've purchased a Corsair Hyper 212 a few months ago, and it works significantly better than the stock cooler, but if I were to overclock this system, there is still absolutely no way that the cpu will remain stable. Its quite upsetting that I have the ability to overclock a CPU but restricted due to thermal reasons. Given, I'm new to all of this, and my system isn't even thermally optimized.
Mount the air cooling setup to vent out the top and have an intake low from the outside.
I recently saw some Peltier Thermo-Electric Cooler projects, and I am curious Linus, would a TEC setup (which produces ice on the CPU side) with a water cooler on the hot side allow for a higher overclock than a traditional water cooler? The hot side with the water cooler should be very hot, but since the processor remains cold, the heat should be easily dispersed by a water cooler.
Just an idea if you wanted to tackle the project, I would be interested to see the max TEC overclock for an i7-4790K vs a traditional water cooler.
Hi Linus, I hate to burst your bubble, but just correcting the temps by adding a correction factor doesn't exactly work. The heat transfer in the radiator (for water cooling) or tower (air cooling) will be dependent on the temperature differential between the medium being cooled and ambient. So at low ambient you'll have higher heat transfer. This means that if you make that adjustment there's no compensating factor for the difference in actual heat transferred during the cooling activity. However, if all you're talking about is 11C-ish, it shouldn't make THAT much difference. Just thought you'd like to know. :)
Pleased to see that some guys have a foot in childhood liking assembling mecanos and showing proudly their expensive assembly.
Absolutely love this video Linus! Possible suggestion (even though I know you probably have years worth of videos to complete) is a comparison of an H100i (or the best equivalent out-of-the-box cooler at the time) VS. say.. a custom loop of your choice. I know the price difference would be substantial, but it would be nice to know the temp. differences between out-of-the-box and custom insanity :)
Actually a carat is a measure of purity, not weight. I dont think the two thermal compounds you referenced have such a dramatic difference in purity or it would be drastically more expensive gram for gram. They probably labeled them to make it seem like there is a performance difference when there probably isnt much if any.
Some years later, could you do a small turbine - jet engine fan test, slightly extreme airflow would be interesting to see if that pulls away heat or just the air around.
I built a rig with a FX-9590, 16GB of DDR3 1866 and a single 2GB graphics by AMD. Plus I have two DVD drives, four WD Black HDD's and two SSD's by Corsair.
I decided to go air cooling because I'm the old-school type of builder. I don't like the idea of having liquid inside my case.
From MY personal experience, a case must be closed if you're using fans. For a very simple, physical reason: airflow. We all know that hot air is thinner than cold air and goes up (watch hot air balloons and you will see). Having front fans blowing in at the bottom and rear fans blowing out at the top will create a perfect airflow system as the air comes in cold, gets hot, goes up and comes out at the back. With an open case, this flow simply doesn't happen.
I also picked pretty normal fans. They are mostly 12's and to cool the CPU I have the mighty CM Hyper 212 Evo, with a second fan creating a push'n'pull system.
This CPU is known for eating power and frying eggs but you know what? My CPU rarely goes over 60 degrees, even when I'm gaming. I'm running it at 5gHz and I haven't had a single problem. Without any CPU management, simply running the OS and some random softwares, on Windows I get about 30 degrees. On Linux, I get about 25 degrees. It's not that quiet, I'll give you that. But it's cheaper than the liquid cooling and I have some awesome headphones that are noise-cancelling and I can't hear a thing. The wife needs to poke me when she has something to say. A few fans wouldn't interfere with the system's usability or performance. And fans look way cooler than pumps.
I only have some questions regarding your test results. First of all, did you take into consideration the thermal inertia of the cooling liquid? How long into the test did you take the final measurements for the temperatures? Another factor is the formula that you used to calculate or compensate the room temperature. Just adding the temperature difference to 20 degrees is not quite correct. All facts taken into consideration, a different type of air cooler, mainly an all copper one could have had better results than the water cooler due to the fact that there is only one direct exchange of energy when, in the case of the water cooler you have two, both of wich are subject to faults in thermal conductivity.
Because of the number of variables, you will never get the same numbers he did. This is just to show relative performance, not actual performance. So it doesn't matter. All we need to know is what is better.
i wish he'd mention price advantages, that way we could easily figure out if the temperature difference is justified
"If you haven't seen my video about the fans........frigin awesome" this why i subscribe-along with all the useful info he gives us- he's fucking hilarious
I tried replacing the stock fans on the H80i with the dual fans from the Cooler Master V4 GTS. Works surprisingly well and noiseless at the same time.
Previously, with the stock fans the CPU temperature approximately 40~42 deg with normal computer usage. After installation, the temperature is around 37~38 deg. *Edit: It is around 27~29 deg idle*.
I used Corsair Link for the temperature reference. My CPU is the i5-4670.
Sound levels have reduced considerably as well. I used a simple app, Decibel 10th to measure. With the stock fans I was getting around 67+ dB but with the replacement fans I was getting around 47+ dB with normal computer usage. I measured the sound with the iPhone about 10cm away from the computer for both measurements.
I'd like to hear your opinions on the Raidmax Agusta and setting up an optimal aircooling rig on it.
I get why the same fan was used in all the tests, but it feels a bit off to use an air cooler meant for 140mm fans & then downgrade it to 120mm fans. Those fans aren't even large enough to reach the outermost heat pipes. It might almost be better to compare the silver arrow to an H110 (or the never equivalent), & just pick fans from one or the other to rig up a mounting for comparison. The real moral of the story though is that 120mm radiator closed loop coolers are a waste of money.
I like how the stock H100i at load with HIGHER ambient air temperatures outperforms the H100i with lower ambient temps and the NF-12 fans that he pushes for so much, because it looks like the stock fans outperform his recommended fans
It's called silence
***** Yea, well its also called PERFORMANCE
You do realize that the amount of overclocking you can do with this setup isn't limited by the temperatures. RIGHT!!?!?!
What you just said is retarded. The major limiting factor of overclocking, temperature, isn't limited by the higher temperature of lower performance. You are a GD genius! Haha. Shut your mouth.
James Porras Please stop being stupid. If you've ever had a half descent CPU cooler you would know that after a certain OC your processor will be unstable regardless of the temps. There is a limit to the amount of voltage you can throw at these things. I'm guessing you use the stock cooler and make dumb assumptions on videos like these.
Such old school Linus goodness! :)
