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? As exhaust, you've got warmer air pushing through the radiator. As for their differences, it’s very simple: Intake fans brings fresh air into the PC, while exhaust fans kick stagnant air out. will this make the cpu hot if hot gpu air is in the radiator? 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. I would put radiator in top with front full of intake fans, high pressure rated fans. It's worth mentioning that I have my AIO radiator at the front of the case due to "case reasons". 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 suggest 280mm radiator, but then it would flow more air then front intakes … Currently running 2x AIO CPU rads top mounted, 1 intake, 1 exhaust because i couldn't decide! Which way should the fans on the aio cooler go (i think push is better and im leaning that way). 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. I'm curious. I didn't want to open up the top of my case for dust purposes. More reason to make the decision based on your case, hardware, and environment. 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. Nice rig btw 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. There is no catch 22. Cooler CPU temps with no real effect on GPU temp, even at extreme CPU temps. 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). 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. filters on the aio fans would also hurt there performance so if you can have more filtered fans as intake … Not ideal as you're not getting cold air coming through but it didn't adversely impact my temps. I've done a bunch of research and it seems like it's half and half so i'm not sure. The heated air is removed and the cycle continues. I've got a case with a 120mm intake on the front and an 80mm intake on the side, but no exhaust fans. Q: How do I clean my AIO radiator? Its kiddie cooling. I was using a 280mm radiator in the front initially, I then swapped for the 240mm radiator … You have to move the heated air out of the case. The coolant absorbs the heat, the radiator provides an increased surface area for the liquid to be cooled by air flow. Hi I’m planning to build a pc with a meshify c the case comes with two stock fans one intake and one exhaust. a) lower front as intake - a la HanoverB. 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. again, this has been demonstrated to work. 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. I would put radiator in top as exhaust. The reason for the difference is that the top of my case cannot take a 280mm radiator. Jul 22, 2017 @ 7:40pm Originally posted by Oh Lets Break It Down: Originally posted by Big Boom Boom: Yes, bad air flow. Side-mounted fans can be intake or exhaust, depending on the setup. It depends on how the other fans in your case are mounted. level 1. Bottom = Intake Side = Depends Top = Depends RAD fans ... always blow in, unless ya believe in magic instead of than the laws of thermodynamics. Have a Corsair H110i AIO cooler which will go in the bottom. Works well. aio cooler radiator as intake on front? I would be mounting the radiator in the top of the case and would look like this setup.. 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. 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. 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. the question is will the H60 AIO 25mm wide fan + 27mm wide radiator in that front intake clear the RAM sticks.. For clarification, positive pressure entails having more air flowing in than out, which means more intake fans than outtake fans. This will make it harder for the cpu to shed heat. 2 front and 1 back. I’m going to … And these differences are going to be exacerbated noticeably if the graphics card(s) aren't included in … is this a bad air flow? If the radiator fans are exhausting, they would be pulling hot air from the gpu through the radiator. I switched my old H100i setup from top to front Mounted, reducing temps by up to 10 degrees. That’s my set up, cold air intake at the front, exhaust at the top. ... Front intake rear and top exhaust. Once I do the CPU AIO successfully it will be time to work on AIO for the GPU. 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. Good looks with lots of funtionality. With the radiator at intake, the radiator will perform some degrees-C better, but you're now pushing warmer air into the case. Using radiator as intake on the other hand hardly effects GPU temps in game. 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. 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 … After much extensive testing on UTube (Jay's Two Cents & Linus Tech Tips are 2 good channels to watch) It really does not matter. The Intake-exhaust direction should go front-to-back and bottom-to-top. Putting the AIO in exhaust or intake has a really minor effect on temps actually. 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. Manage Your Cables and Other Obstructions. Cs342, I suggest you turn the side fan to exhaust, add a rear fan to exhaust. AIO as exhaust or Intake? This is the role of intake and exhaust fans. 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. Very nice, good read. If you have the radiator as intake it will be cooling with fresh air from outside the case, which is more effective. Specs: I have two intake fans on the radiator and a single exhaust fan at the back. I used them initially in the XPS 8930 mod, and they were great at keeping the i7 8700 temps in check. Why didn't I test this sooner?Top vs. Front radiator placement with different GPUs tested! I'm new to water cooling and just bought a corsair aio. I have a radiator in push (outside air intake), 2x180mm fans, and a single 120mm exhaust fan. 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. That's my problem because using it on top is the only option for this case. 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. Because I'm planning a small footprint build, where I might have to put the AIO radiator under the PSU. In short I always push air through the radiator and exhaust at top. Heat rises, so its best on the front or side as intake. 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. 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. Intake on top is a no-no unless its the only option like it is for my 280mm AIO in the PC-O11D. 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. I have it as an exhaust with 3 intake fans. AIOs are best used as intake. For your system, there is no reason not to set the fans on the H115i to exhaust out. #2. 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. 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. Push or pull makes no difference for the radiator. A: To clean your AIO radiator, you need to blow compressed air through it in a backward direction. Nice case! Depends mostly on case airflow/spacing and the actual GPU cooler. 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. Also which way for cooling would be better to install the aio? Zombie Cat. So essentially the PSU would have to be cooled by the exhaust air of the radiator. 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. aio cooler radiator as intake on front? You can try the fans to be intake or exhaust. Q: Should radiator fans be exhaust or intake? 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. That's an AIO. 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. A: The idea is to create static pressure in the case. if install radiator fan as intake its just work as intake fans?
