It's water cooling so I though they would be a lot better but they aren't.. they are around 75-80C without the window open.
I have a Heatkiller 3.0 waterblock on an i7 950 (@ 4.0 GHz), 2-GTX 460s in SLI, and all the optional fans installed. Front and side fans are intake and the top and rear are exhaust. I have the Swiftech H20-220 rad mounted in the top too, and it doesn't restrict airflow out of the case at all if you are using both 200 mm fans up top. As long as the net exhaust cfm is greater than the net intake cfm, you will have positive airflow through the case and the rad:
Intake: 1x140mm (62.5 cfm) + 2x120mm (94.54 cfm) + 1x200mm (166 cfm) = 323.04 cfm
Exhaust: 2X200mm (332 cfm) + 1x120mm (47.27) = 379.27 cfm
Running a Prime 95 blend test or Intel Burn, my cpu never gets above 60 C. Idle temps are 32-36 C. Normal game-play, temps hover around 44-48 C-ish; although, my AS5 hasn't reached 200 hrs of burn-time yet, so those temps will get even better.Edited by RJT - 1/23/11 at 3:33pm
