I'm using Windows 7 Ultimate, and I have an Asus M2N-X motherboard and an AMD Athlon 64 X2. If I do something, what is raise the temperature, the OS raise also the fan speed. It will stop about 3,3k RPM.
If the temperature has reduced, it won't reduce the speed of the fan to slower RPM. I can solve that problem if I send it to sleep mode, and wake it up...
Can it somehow do it automatically?
