h80 use as intake or exhaust? - Page 2

post #11 of 12
I've extensively tested both setups, and found that the decrease in CPU temps were more dramatic than the increase in case and GPU temps. My vote is for intake.

Hey guys - new to the forum - I also have an h80 with an antec ElevenHundred (do they just call em 1100?). I have my 2 front 120mm doing intake,120mm fan on inside of case on radiator pushing through the radiator and 120mm fan on otherside of radiator pulling out the back, with the massive 200mm fan on top as exhaust. Last night I hit about 65C with my i7-3770k 3.5ghz @ 4.3ghz under full load. Did a little research this morning and came across this site: http://blog.antec.com/cooling/asetek-air-flow-matters/ - it's a different cooling system but very similar.

Check it out, I think it explains it pretty clearly (diagrams and temp differences)...

I'm going to go home after work and flip my fans around so intake comes in from outside the case through the radiator and pull from the radiator and out through the top and the front of the case.

(excuse my ascii diagram)

Case|Fan-->radiator-->fan--->^200m fan and also 2 120mm fans out the front of the case blowing on my HD's



Hopefully the 200mm exhaust will pull out most the heat the radiator will pull in..

I might try leaving my front fans pulling in air from the front and let the top fan handle all the exhaust. I'd have to calculate the CFM to see if it makes sense to do it that way, I can create a flow to make it all go out the top of the case.

I'll give an update tonight and see how the front fans matter in this config.
