HAF 922 fan setup

post #1 of 6
Thread Starter 
I have been experimenting with different fan setups and found the optimal setup on my HAF 922. 1 120mm and 1 200mm fan at the front on intake, 1 side 200mm intake. 1 120mm exhaust at the rear, 1 200mm exhaust at the top. Also the the psu and both graphics cards exhausting out the back. Interesting observations I got significantly cooler temperatures when mounting the 980x cooler horizontally (fan down) vs vertical (fan right facing ram). Mounting a fan at the bottom really helped to cool the graphics cards but was incredibly noisy for some reason possible due to the thinner bottom?

CPU with speed step on is idling about 25 degrees with speed step on the lowest clock and 32 with it off at 3.86ghz. I have not seen over 50 in normal use/gaming etc. North bridge idles around 45 which was a big improvement when adding the 120mm front intake. Room temperature is about 21-22 degrees.

thats a great fan setup, the noise maybe a loose screw? I'm not too sure, but it happens to me sometimes and I just need to tighten the screws to get rid of it!

Yeah I have everything tight and even tried to isolate the fan with a little strip of rubber band but it didn't work. I think it's because the bottom is very thing sheet metal and it just transmits more vibration.

I have the HAF 912, I get better results by not utilizing the side fan. I really think it just mucks things up, but YMMV.

The problem I have is both graphics cards are pretty close and the top card thats blocked gets quite warm without the side fan.
