Okay... got this computer its new... It is missing any kind of fan in the back of the computer.. It only has a heatsink and then a fan blowing in from the side of the case. The computer would turn off by itself pretty often.. so we opened up the sides and now have a box fan blowing through the thing.... But even with this.. it still causes problems of turning off.... Once it turned off and I hit the power button again and it turned on for like 5 seconds then turned off again.... So that made me think it was an overheating issue.

Oh and also I got an error message on startup that says the fan is running at a lower speed then recommended.... so maybe a heatsink problem?

But, is just two 80/120mm fans in the back going to really do that much if a box fan cant even do it..? Or is there another problem..

Thanks

Sounds to me as CPU is overheating or the BIOS thinks it is, causing the puter to shut down to prevent any irreparable damage.

Presumably you have TIM between the CPU and heatsink.check this topic

Make sure you have applied enough (NOT too much)

case fans in general are only there to Draw Cool air in (from Front / Bottom) fans at the Back of the case and top Expel warm air.
As long as the Fan/CPU heatsink is designed for the CPU then it should be ok.

I suggest that you fill every available fan slot in that case. Make sure that the fans are blowing in the correct direction. Then, if you don't wanna do the fan thing or after, check to see the thermal paste in between the CPU and heatsink. There should be a little pad supplied with the HSF (heatsink and fan), if not then add more.

Found the problem.. after lookin at the hardware specs... the temp would rise so quickly.. and the CPU fan would run at 0 rpm... so its a bad heatsink... we ordered a new one... and now al the fan spots are filled and the comp is keepin cool :thumbsup:
