My configuration: P4 2.8Ghz w.533Mhz FSB 1024MB 3200 Ram in two 512 sticks Shuttle AB60R mobo http://us.shuttle.com/specs.asp?pro_id=308 ATI Radeon 9800 XT 256MB Video card Fan pulling air in from bottom front, Fan pushing air out from top rear The CPU is always cool, even after hours of gaming, so that's not an issue. The motherboard will reach up to 160 degrees F during gaming, according to Sandra. I have never had the computer lock up or anything, it is brand new, i just built the machine. Sandra says the mobo is too hot. The mobo is the correct specs for the CPU. Do I need another fan blowing onto the mobo from the side of the case, aimed at the video card? I was thinking about jimmy rigging one to the side of the case to see if it helps. any other ideas/thoughts?
