Radiator thickness and number of fins per inch (FPI) increase heat dissipation surface, but also make it harder for the fan to blow air through it. The CPU cooler’s fans are connected to CPU_FAN headers on the motherboard, the power supply’s fan is wired internally and requires no […] So the more FPI and the thicker the radiator is, the higher the heat dissipation increase will be by having fans in push-pull configurations. Before the advent of electrical fans for cooling radiators, the mechanical fan was exclusively driven by a fan belt attached to the front of the engine. Planning on building a computer but need some advice? As for fan placement, If you're only placing fans on one side of the radiator, it doesn't make much difference. A500 Dual Fan CPU Cooler. CUSTOM COOLING. The CPU temperatures were a little higher when the radiator was mounted at the top during gaming and was around seven degrees higher under Boinc, but were still well within safe limits and the fans did not have to speed up to compensate. EXTREME CPU COOLING. The aio fan is blowing air from inside the case towards the radiator. Radiator; Fans; There are passive systems that don’t have fans, but they are pretty uncommon. ... (fans on top of radiator) with 2 exhaust and no intake. I posit that the individual case, cable management, and components is the key factor. I have the same AIO and the RGB's failed in under a month on all the fans, and personally I think it looks better with just one hidden strip light in … The second test I tried to load up the CPU and ran Boinc on all cores in order to load the CPU a little more. The GPU, however, did not run any cooler under gaming, which was to be expected. So I decided to do some testing myself and find out the answer. ASUS ROG Strix LC 360 RGB All-in-one AIO Liquid CPU Cooler 360mm Radiator, Intel 115x/2066 and AMD AM4/TR4 Support, Triple 120mm 4-pin PWM Fans (Addressable RGB Fans) 4.5 out of 5 stars 40 $239.99 $ 239 . 240? This is pretty interesting and I didn't expect to see quite such a difference. /r/buildapc is a community-driven subreddit dedicated to custom PC assembly. New comments cannot be posted and votes cannot be cast. GPU, etc. When you mount an AIO on top, you allow the fresh air to get to your GPU, but the heat exhaust from the card rises up into the radiator which slightly raises CPU temps. What if I cannot mount my radiator in those two positions? Arctic P12 PWM PST CO[Heavy Duty, PWM sharing support, Silent] Arctic is one of the best when it … How big is your radiator? Side-mounted fans can be intake or exhaust, depending on the setup. The fans will have arrows on the frame indicating airflow direction. Currently running 2x AIO CPU rads top mounted, 1 intake, 1 exhaust because i couldn't decide! With a longer/deeper case there may not be as much of a difference. Cooling performance is entirely a function of case fans and component fans. You should also heed the placement of the fans. I have mine taking cool air from the top and exhausting out the back. However... it's simple. By changing the direction a fan is mounted, it can act as either an intake or exhaust. So yea I should have been clearer stating that this was not a "which cools the CPU better" article, I will try better next time :). Whether the fans are push (inside the case, pushing air through the radiator to the outside) or pull (towards the outside, pulling air through the radiator and exhausting it) is irrelevant. The only one that will really benefit from fan speed is the GPU AIO fan. AIO Radiator Placement, Does It Matter? Radiator mounted on top of the case with tubes down. So sure locking the fan speeds at say 50% would give me the best and most accurate CPU temperatures for both mounting points but my aim was to do a more real-world test. IFORGAME 240T RGB AIO Liquid CPU Cooler, 240mm Radiator, Dual 120mm Windforce PWM Fans, All-in-one Water Cooling Cooler System for Intel AMD. I always assumed that radiator placement made little difference to internal temperatures, I even backed up my thoughts on this by checking out a few YouTube videos. This was not an article I was ever planning to do. On my similar Titan X (P) and 120mm AIO set up, a typical coolant delta would be +20-30C over idle temperature. Personally, before I switched back to air, I actually had the rad mounted outside of the case entirely, and if you can manage that, then I'd recommend that as the best way, but it's a tricky thing to do. Regarding AIO units, such as the Corsair H70/80/90 series, which direction is best for the fan... do we draw air into the box, or extract air out of the box? Experience incredible CORSAIR Hydro Series cooling performance, with each fan running from 400 to 2,000 RPM while in operation, and a thermally optimized cold plate and low-noise pump design for high performance, quiet cooling. report. Try to keep the air flow in your case going in one general direction, with more fans blowing in that blowing out. One good mounting position is to place the radiator at the top of the case with the tubes pointing downwards. Temperatures should stay fairly similar all round with each configuration, but would the fans spin slower on one configuration over the other to maintain the same temperatures? One was a gaming test, which consisted of me running 7 Days to Die standing in my base looking at my two forges until the temperatures leveled out (for some reason this taxes the system a lot). Question- I have the corsair H110 mounted EXACTLY as shown in the picture, (top-mounted) with the fans mounted to the bottom of the radiator. CPU = Central Processing Unit, the brains of the computer, GPU = Graphics Processing Unit, Gives you the shiny graphics. Notice that the fan is located on the opposite side of the radiator hoses. All Liquid Cooling ... CPU COOLING. This is the temperature of my cpu when playing mass effect andromeda on high/ultra: https://imgur.com/a/hcAVt8C 55-61c. This forced the fan to "suck" air through the radiator. So I seem to be getting some flak on social media / Reddit for this one for not testing with the fan speeds locked, I wasnt as clear as I could have been in the article about my intentions so let me try and clear this up a bit. By using our Services or clicking I agree, you agree to our use of cookies. Eg., if you have a fan on the back of your case exhausting air, and you are mounting the radiator in the front, you want them blowing in into the case (pull configuration). Excellent article, Plat. The NZXT case has a solid front from memory, so fans inside the case pushing air out the front makes sense if you have a windowed case. Cheers! Under Boinc, the GPU results were a lot bigger, It ran cooler and the fans run so slow I could not hear them over the rest of the machine. If quiet computing is your thing and your GPU is air cooled, then the top of the case is the way to go. The Intake-exhaust direction should go front-to-back and bottom-to-top. ... enough to do some research or get better direction. Should the fans be set to blow air through the radiatior and out to the top of the case? In this case, should the fans be blowing air into the radiator? You will also be able to identify the Exhaust side as you will see power wires entering the fan motor. I was using a 280mm radiator in the front initially, I then swapped for the 240mm radiator to test my theory. It features a chamfered intake and fluid dynamic bearing that provides silent operations, durability, and powerful cooling performance. The main difference between placing the radiator at the front and top is that a radiator in the front could heat components inside the case and a radiator at the top could pull hot air from inside the case through the radiator which could heat up the CPU. Apparently this was the only way to get it to fit. Nice one Plat, especially like the graphs. hide. You're either running a serious overclock... Or you like things big! Before I show my results I will say that the case I am using is fairly shallow and the front fans/radiator are quite close to the GPU. ... To me the airflow direction is the same, so instead of gunked up fans, now you should be getting a hairy rad? Radiator thickness and number of fins per inch (FPI) increase heat dissipation surface, but also make it harder for the fan to blow air through it. Don't forget that the gpu takes air to outside too. I was in the same location for both tests. Triple Radiator Liquid Coolers. share. Cheers :) Big thanks to wowky for the graphs :), Popular Titles Which Started Life as Flash Games, CD Projekt Responds to Class Action Lawsuit, Billion Beat Receives Steam Early Access Release Date, Resident Evil Reboot Movie Has Finished Shooting, INTERPOINT - Update 1.5 Years in the Making Receives a Release Date, Monster Hunter World: Iceborne Top Tips For Using Lances, Monster Hunter World: Iceborne Top Tips For Using Great Swords, Monster Hunter World: Iceborne Top Tips For Using Charge Blades, Monster Hunter World: Iceborne Top Tips For Using Hunting Horns, The GrinCast Episode 284 - Retro Retrospective, The GrinCast Episode 283 - Game of the Year 2020 Part Two, Intel Core i7 7820x CPU @ 4.3GHz (Voltage set to auto). Limited time offer, ends 01/17. result is that air flow is from front to … Now in my experience, it isn't that dramatic of a shift either way, at least in the cases that I've used, but that is likely a reason for increased GPU temperature. Also make sure the aio pump and fan speeds are set. Best for block to be lower than "some portion" of the AIO, best if you can get the radiator at a higher point than the block/pump. I've never actually used a radiator so this will come in handy at some point for sure. Is there any way to reverse the fans or direction they blow? Front intake:Cooler air coming through the rad, so, in theory, better cooling of the liquid that cools the CPU.However, this blows prewarmed air into the case. The radiator … Do not mount exhaust fans on the bottom of the case; since hot air rises, a bottom-firing exhaust fan will be working against physics by expelling slightly cooler air instead of warmer air. The reason for the difference is that the top of my case cannot take a 280mm radiator. Generally, you want the case fans in front of the case drawing in air while the fans at the rear blow air out. I ran two lots of tests. CPU temperatures were predictably lower when the radiator was placed in the path of unwarmed in-flowing air, while GPU temperatures were lower when inflowing air was not warmed by the CPU. The boost clocks were also slightly higher, which is always a bonus when gaming. Especially if your GPU is not a blower-style card. The 240mm radiator, however, is thicker and has tighter packed fins. The aio fan is blowing air from inside the case towards the radiator. I assumed that the GPU fans had to work a lot harder due to hot air from the radiator being dumped onto the GPU, as you can see below they are quite close to each other. Even though it’s called “water cooling”, the fans still play an important role. This was not an article I was ever planning to do. As far as the fan configuration, as long as cool air from outside the case is being pushed or pulled over the radiator, it doesn't make a difference. Issue Resolved. Corsair aio fan orientation custom corsair h60 processor liquid cooling corsair h60 processor liquid cooling h115i pro fan install direction the corsair a500 dual fan… The Aer P radiator fans are designed for liquid-cooling perfection. In the videos I had watched most had locked the speeds to 60% or so in order to measure temperature changes but I found that 60% didn't make that much difference to temperatures but did produce unacceptable noise levels (in my opinion). Knows more about hardware than safe drinking limits. save. Don't get discouraged!! ... An interesting test would be to measure the difference that occurs when you reverse the fan direction of such a cooler. My current setup for cooling is this: The aio fan is blowing air from inside the case towards the radiator. In 99% of all cases, these parts are all in the water cooling system. Raise the pump speed and fan speeds to a point where they're running faster, but still quiet at idle and then speed up under load. Massive surface area for maximum performance. The primary component fans dwell on the CPU cooler (either a tower fan or radiator fans), the power supply, and the video card. Press question mark to learn the rest of the keyboard shortcuts. Recently, however, I performed a few upgrades to my system and noticed the GPU was getting quite loud. Shorter cases are becoming more popular now since we ditched the optical drive though :). Complete control over your fans, pump, and RGB lighting. Fan Direction and Radiator mounting. There is no One True Way. 4.1k. Top exhaust:Blows directly out the top.However, this is using air that has already been warmed a little by the other components. This is the place to ask! An extra fan was fitted to the front (total3) aimed at the GTX970. Less commonly the fan is in front,pushing, and of course some cars have radiators on the sides, or at the rear… 220 comments.
