The cold air does come in the case warmer once it passes the radiator, however, front mounted radiators are optimal compared to case air intake. is this a bad air flow? And these differences are going to be exacerbated noticeably if the graphics card(s) aren't included in … I have a radiator in push (outside air intake), 2x180mm fans, and a single 120mm exhaust fan. using the radiator as intake, will get your GPU and other components in your case to little cool air, since you will be blowing hot air into your case. Most commonly you want to aim for positive pressure, so if the radiator is in the back or the top, make it exhaust; if it's in the front or bottom, make it intake. Currently running 2x AIO CPU rads top mounted, 1 intake, 1 exhaust because i couldn't decide! a) lower front as intake - a la HanoverB. I've got a case with a 120mm intake on the front and an 80mm intake on the side, but no exhaust fans. This is the role of intake and exhaust fans. Have a Corsair H110i AIO cooler which will go in the bottom. aio cooler radiator as intake on front? Bottom = Intake Side = Depends Top = Depends RAD fans ... always blow in, unless ya believe in magic instead of than the laws of thermodynamics. Generally, it’s best to have as few obstacles as possible between the intake fans on the front of the case and the exhaust fans on the rear and top of the case. I’m going to … Depends mostly on case airflow/spacing and the actual GPU cooler. The reason for the difference is that the top of my case cannot take a 280mm radiator. For clarification, positive pressure entails having more air flowing in than out, which means more intake fans than outtake fans. I'm curious. It's worth mentioning that I have my AIO radiator at the front of the case due to "case reasons". I would put radiator in top as exhaust. Good looks with lots of funtionality. Cooler CPU temps with no real effect on GPU temp, even at extreme CPU temps. Push or pull makes no difference for the radiator. ... Front intake rear and top exhaust. If you install the H60 in either top exhaust position, you can configure a push/pull radiator sandwich with two 120mm fans, which should provide plenty of air flow out of the case. Putting the AIO in exhaust or intake has a really minor effect on temps actually. If you have the radiator as intake it will be cooling with fresh air from outside the case, which is more effective. Exhausting air form inside the case through a radiator may give you a few degrees higher CPU temp in games because GPU makes a lot of hot air. I have a Corsair H110 with stock fans and I run push intake with the radiator on top, exhaust out the rear 2 fans intake from the front. Jul 22, 2017 @ 7:40pm Originally posted by Oh Lets Break It Down: Originally posted by Big Boom Boom: Yes, bad air flow. The key, therefore, is to add fans that either get rid of this ambient heat or bring in fresh, cooler air to be used. Also which way for cooling would be better to install the aio? Running with the radiator in the front with EVGA’s fans pushing, and with the 200mm fans in the top as exhaust, our numbers output as 59C over ambient for … But the impact there would be negligible, however the custom loop is going to pull in some graphics cards and cooling efficiency is going to become a priority. Glad to see my setup is optimal for my needs (and seeing as my hearing sucks noise isnt much of an issue for me) Thanks mate, cheers. After much extensive testing on UTube (Jay's Two Cents & Linus Tech Tips are 2 good channels to watch) It really does not matter. filters on the aio fans would also hurt there performance so if you can have more filtered fans as intake … Two stock 140 mm fans intake in the front and a stock 140 mm fan in the back for the moment, will stick some pretty ones in later, and I guess the top mount PSU (SeaSonic 650 Plus Focus) will exhaust a little too. Typically, case designs are deficient in respect to the fact that if you put a AIO or use exhaust fans on top, you create an air intake at your real grilles and slot covers. Works well. the question is will the H60 AIO 25mm wide fan + 27mm wide radiator in that front intake clear the RAM sticks.. I didn't want to open up the top of my case for dust purposes. That's my problem because using it on top is the only option for this case. As for their differences, it’s very simple: Intake fans brings fresh air into the PC, while exhaust fans kick stagnant air out. Q: Should radiator fans be exhaust or intake? Yes, and the suggestion in the manual to use the fans as intake is contradicted by the picture right above it that shows the fans in an exhaust position and arrows pointing up and out. I would put radiator in top with front full of intake fans, high pressure rated fans. I switched my old H100i setup from top to front Mounted, reducing temps by up to 10 degrees. Manage Your Cables and Other Obstructions. I would suggest 280mm radiator, but then it would flow more air then front intakes … I have it as an exhaust with 3 intake fans. As exhaust, you've got warmer air pushing through the radiator. Hi I’m planning to build a pc with a meshify c the case comes with two stock fans one intake and one exhaust. As intake fans usually have inlet air filters which resist more air as they get clogged with dust ... you'll want to have at least 1.33 times the number of intake fans as exhaust fans. I would be mounting the radiator in the top of the case and would look like this setup.. aio cooler radiator as intake on front? Because I'm planning a small footprint build, where I might have to put the AIO radiator under the PSU. The air coming in if it is an intake, is not cooler as it is heated by the radiator as it passes through, so increases the internal temp of the case and components. That’s my set up, cold air intake at the front, exhaust at the top. again, this has been demonstrated to work. Nice case! I'm new to water cooling and just bought a corsair aio. I used them initially in the XPS 8930 mod, and they were great at keeping the i7 8700 temps in check. Zombie Cat. You have to move the heated air out of the case. if the case has good airflow more than enough filtered intake to keep up with the aio exhaust and the aio are unloading the vast majority of the heat then having both blowing air out the top would be best. There is no catch 22. The air doesn't have much time to heat up inside the radiator, so I'm assuming the intake vs, exhaust temps can't be that different? I was thinking of configuriong it as exhaust becuase if I do intake then the only exhaust I will have is the one 120mm fan at the back. AIO as exhaust or Intake? If you have the cpu aio radiator as exhaust, it’s trying to cool the cpu with the air from inside the case, which may have already have been warmed up by the GPU. The Intake-exhaust direction should go front-to-back and bottom-to-top. More reason to make the decision based on your case, hardware, and environment. I used two AIO coolers for this test, one is a 280mm (EVGA CLC 280 Liquid CPU Cooler) and the other is a 240mm (Corsair H100i V2). Once I do the CPU AIO successfully it will be time to work on AIO for the GPU. In my previous system I had my radiator sitting outside the case, but this time I'd like to get it mounted in or on the case in some way. Its kiddie cooling. So essentially the PSU would have to be cooled by the exhaust air of the radiator. If you do mount it on top then exhaust is better but not for cooling reasons but so it does not suck in so much dust. level 1. Heat rises, so its best on the front or side as intake. A: To clean your AIO radiator, you need to blow compressed air through it in a backward direction. I've done a bunch of research and it seems like it's half and half so i'm not sure. If used as an exhaust, the internal components are still getting the same temp air input as before, but are now assisted by the radiator so the CPU will run cooler. Cs342, I suggest you turn the side fan to exhaust, add a rear fan to exhaust. So, if you want optimal overall temps, you should give your radiator fresh air. My Phanteks Enthoo Luxe case has one front 200mm fan, one rear 140mm fan, and a Corsair H100i AIO cooler (with two 120mm fans) pushes air through the radiator and exhausts out the top of that case as well. If the radiator fans are exhausting, they would be pulling hot air from the gpu through the radiator. I was using a 280mm radiator in the front initially, I then swapped for the 240mm radiator … This will make it harder for the cpu to shed heat. For your system, there is no reason not to set the fans on the H115i to exhaust out. Using radiator as intake on the other hand hardly effects GPU temps in game. 2 front and 1 back. It depends on how the other fans in your case are mounted. Not ideal as you're not getting cold air coming through but it didn't adversely impact my temps. The coolant absorbs the heat, the radiator provides an increased surface area for the liquid to be cooled by air flow. You can try the fans to be intake or exhaust. A: The idea is to create static pressure in the case. If anything a classic gaming GPU with open heatsink delivers much more hot air into the case and in an eventual exhaust AIO than the one passing through the radiator. AIOs are best used as intake. That's an AIO. Q: How do I clean my AIO radiator? Intake on top is a no-no unless its the only option like it is for my 280mm AIO in the PC-O11D. Although if I get the AIO with only One 120mm fan I could do that as intake and keep one fan at the top as exhaust. Side-mounted fans can be intake or exhaust, depending on the setup. Very nice, good read. The heated air is removed and the cycle continues. Which way should the fans on the aio cooler go (i think push is better and im leaning that way). If not, use the Noctua 120 x 15mm wide fan instead, the NF A12 x 15 fans which are decent fans and come in black as well. i just installed radiator as exaust on front i i see my Open air gpu RX470 Runs like 85c and worse is just goes 89c went throttling. for example having 1 or 2 fans as intake in the front of your case, and 1 side intake, should do the trick, and your Radiator as exhaust on top. will this make the cpu hot if hot gpu air is in the radiator? #2. I have two intake fans on the radiator and a single exhaust fan at the back. With the radiator at intake, the radiator will perform some degrees-C better, but you're now pushing warmer air into the case. Why didn't I test this sooner?Top vs. Front radiator placement with different GPUs tested! Specs: In short I always push air through the radiator and exhaust at top.
