Kaytfoh: I would run the H100 as intake, that way your not trying to cool the radiator with already warmed up air from internal heat. If anything, only have the top back fan as exhaust. Which would create a more positive pressure system. Helps with dust, and you know your 690 wont ever starve for air.
BTW, dont expect it to be quite with all those fans. I had my YL hs fans in my case, H100 pull/intake, front intake, lower intake rear exhaust. It go quite loud. Swapped all back out to the stock Corsair fans, H100 stock pull/intake, front stock intake. NO bottom fan, but left a YL 140mm medium speed for exhaust. My system is now dead silent, which I enjoy. And my temps are damn near the same, just 2-3*c hotter at idle and ~5*c hotter under full load.

Either way, you can run all those fans just fine, but I would just keep the H100 fans intakeing air into the system. Whether you have them push from top down, or pull from rad in.

Sorry but could you make that a little clearer for me, in the like of..

Top rear: exhaust, fan size, fan speed
Roof: intake, fan size, fan speed

Etc, just to make it a little clearer because there are so many opinions it is easy to get a little lost :S

Thanks

My Current Setup:

Top: H100 stock 120mm fans, pulling through the radiator as intake. (1300-2000rpms Balanced profile on H100)
Front: 550D stock 120mm fans, intake. (800rpm+ pwm controlled from motherboard header)
Top Rear: 140mm Yate Loon medium speed, exhaust. (1500rpm max speed.)
Bottom: No fan.

That makes tonnes more sense, however, with the H100s acting as in take downflow, how does air manage to escape at the rear exhaust? Can you explain the airflow there at all? And would it be better to leave the middle cage on and attach a 2nd intake fan on it to act as a push pull onto the GPU area?

Thanks

Well, in my case, I have both HDD cages removed completely. So both my fronts are clear to my GPU's.
As for the rear exhaust, on my H100 rear most fan, as soon as it sucks air through it gets sucked out right away, by holding some tissue in there I can see that its pushed down, but then pulled towards the rear. The forward most fan pushes more down towards my GPU's.
Remember I dont run any side fans at all. Trying to keep silence myself.
Ignore the bottom fan, completely removed now.

That actually suits me fine because I will only have one hard drive in the bays, the primary disk is actually going to be a PCIE x4 RevoDrive, so the air flow there will cool both the GPU (GTX 690) and the PCIE SSD.

However, would there be any airflow getting to the hard drive I see there in the lower optical bay?

My HDDs/SSD are in a Xigmatek 4 in 3 cage installed up there. Does have a 120mm fan, it is hooked up and runs, but yes it really doesnt provide much if any intake air. Just keeps some air moving over them, they stay 40-45*c most of the time.

Just to try and clarify, I'll be using a m-atx rog maximus v gene (awesome board, even if its m-atx) and the below picture is the board fitted in the case I will be using, I just have some questions regarding that.

All of the air coming in at the top front intake will enter the GPU area and be sucked up by its fan I'm guessing (so really cool GPU is a good plus there) however it strikes me that the lower front intake will hit the psu, come up and then be directed again towards the GPU area, so if I am thinking rightly, both the intakes will only serve the GPU. Now on top of that you have the roof fans pulling cold air in onto the h100 rad going through that (will the air be that heated so as to cause a problem on the GPU PCB?) and most likely some will spread left and right, the air going left will go back up I imagine and exit via the rear exhaust, the right flow of air will head towards the hard drive?

If I am right in my guestimations should I take advantage of one of the side fans and would that interfere with the airflow present at all?

Thanks

the front plast part of 550d is not ugly to see ?
post #4300 of 8654
What plastic part? The IO plate? Not to me. Looks nice in silver but having a black option would have been nice too
