I have a 650 Duron and a KT-7 RAID mobo. The fan attached to my processor is a CoolerMaster. In my BIOS, there is a way to check the temperature and fan speed of all the fans and the temp of the processor. When I boot my computer, the processor is about 18 C. However, it says the fan is running at 0 RPM. After about 5 minutes, the temperature is all the way up to 25 C, and it keeps going up. I downclocked to 550 and lowered the voltage a bit, and it seems to even out at about 33 C. Since I got the processor intending to overclock, and since i have to actually DOWNCLOCK, I'm not very happy. The fan IS running, however, because I can see/feel it when I open the case. What is the problem? Is it just that CoolerMaster is a crappy fan? Or is something wrong with my processor?
