Is the stock fan supposed to automatically speed up and slow down depending on CPU temp/load? If I leave Asus Q-Fan off, the fan stays at 2000rpm (is this the maximum speed of a stock Intel fan?) and never changes speed, regardless of load on the CPU. With Asus Q-Fan ON, the fan speed stays at around 700rpm and never changes - this also causes the motherboard to give me a "CPU fan error" every time my PC starts, and obviously the CPU temp is a bit high. There is no option in the BIOS for a "CPU target temperature" so I can't get the fan to spin any faster with Q-Fan.
What is the normal way to regulate CPU fan speed?
