I have the chieftec case that looks like the old Alienware case with the 2 80mm case fans in the back pulling air flow out, 1 80mm case fan on the bottom of the case pulling air flow in, and 1 80mm case fan in the hard drive cage pulling air flow in. My PSU is the Antec TrueBlue 480Watt that has 2 fans in it.
Currently with full CPU load my temp is 118F and my motherboard temp is 93F. The Q Fan control ratio in my bios setting is set to 12/16 and my retail fan is @ 3994 RPMs.
I'm still waiting on delivery of my Thermalright SP94 and Panaflo fan.
