Got my case which is a Rosewill Challenger. It has a 140 fan on top which will be setup as exhaust (I think it already is) There is also a 120 mm intake on the front of the case, essentially to cool the storage devices. oh and the the PSU is at the bottom, and the fan draws the air from the outside as well to cool the PSU unit itself.

I can also attach 2 120mm fans on the side panel. which will be either intake or exhaust depending on how I setup the Corsair H80 that I have. I am going to attach 1 120 for now (the exhaust fan off the rear that I took off) so techically without the rear one, I got 1x140 as exhaust, and 2x120 for intake right now. might make it 3x120 for intake


I see some people run it as exhaust because of 2 reasons.
  1. you won't get nearly as much dust in the radiator since air is drawn from inside
  2. it keeps to the tradition/idea of 'back fan is always exhaust'

now, intake makes more sense to me because
  1. the outside air will ALWAYS be cooler outside the case, no matter fast you have the air moving through the case
  2. you can prevent alot of dust on the fan/radiator by putting a small filter on the fan outside
  3. radiators are supposed to work with cool air going through them

Now I can't tell you what the temp of the room is when the computer runs (I didn't have a side panel on my old one, and when my computer was running, it was around 8 degrees higher compared to the other rooms. (around 73 in other rooms with AC, runs around 79-80 in my room with computer) with the new setup, and it being cased. I have no idea

so here is a poll with people who have either used it and saw improvement over another, and for suggestions. I will take all considerations.

thanks!

ps remember H80 is a push pull setup

ps2 I just realized the top fan gets in the way of the hoses if I put them on top, so I have to put the hoses coming from the rad to the bottom, which will probably be in the middle of the mobo. what that means is I have to wait until my mobo comes here, install all my mobo stuff 1st, then put the radiator/heatsink on,.

I'd do intake, that's what I did with my h50, and it lowered temps a 2-3C, plus it was nice to have some air blowing over the motherboard. The temp of the rad never got too hot where it was blowing warm air, and I also had a top exhaust, so I went with it.

i think it all depends how you configure your fans for your case, when i had my h50(before trading it up for custom liquid) i find it to be a bit better using it as an intake because on my old nzxt phantom i find that i get about 5-8C cooler since i used the triple 200mm as a exhaust and everything else pull cool air in and from the bottom of the case and exhaust hot air out from the top

I'm stubborn. I've setup every H50 I've installed as exhaust. Although I always do a push/pull setup, In my mind that compensates slightly and doesnt disrupt the rest of the airflow in the case.

I have mine as an exhaust to maintain airflow and aesthetics. I tried to mount it in a different position to utilize an intake orientation, but the gains were very minimal and I hated where it was mounted.

Push/pull with medium Yate Loons which are cranked down a bit to lower noise with 26C ambient temps and I will just crack the 60C mark after a few Intel Burn runs.

if you have good airflow, it is fine to set your cooler to exhaust, since air keeps getting introduced to your fans. otherwise do intake and make sure you have good exhaust fans.

on my haf 922 + H60 i have it set as exhaust, on my 650d + h100, it is set as intake.

Well, this is my thought on the subject. I have been thinking about this for a while, since I plan to grap one of these enclosed coolers soon. Waiting to see what Astecks cooler brings to the table. If you go intake, you will be sucking in dust and plugging up the rad, unless you filter your intake, which will cut down your air flow. So, I have decided that I will go exhaust, and have the rest of my case fans as intake, all filtered intakes ofcourse. This should keep the dust down, and supply plenty of cool air!!

I think you need to try both. Intake will be better for the CPU but might not be good for the chipset or GPU. Then again it might not change a thing other then cooling your CPU better. Switching fan directions is super easy, might as well make a decision based on solid data.
