Ok no where in my bios can i tell the stupid board NOT to shut my CPU fan off. There are lots of BIOS settings to set it at what temperature it should either be at full or shut off completely. I have set it to the lowest setting which is 25 to go full power but my temps keep staying at 23-24 when not in use and the sucker just turns off. In my previous mobo it alwasy was running full blast. This has to be bad for it!! OMG! Only if i play a game or do some encoding/decoding does it turn on -- Jesus my CPU is going to burn. I have read that the DFI mobos read the temps imcorrectly. I am just using the stock AMDx2 3800+ HS/Fan combo.... no way it's working that well. IS there any way to set it to spin full bore all the time -- it's quiet and besides my video fan totally covers its noise LOL>
