I have DG43GT desktop board and I have noticed that the speed of system fans does not change even when there is the load on the system. I have observed that my CPU temperature rises to 75C. I was surprised to see that. There is no set threshold temperature in the BIOS, so how is the fan control supposed to work? In my system I have 2 system fans which are running at 700 rpm, but are evaluated at 1900 rpm at 12 volts. Obviously the fans are slowing down because of the dropping the voltage? Would I need to have fans of cases that have RPM sensing to control the system fan to work properly?
