I have 3 chassis fans, 2 intakes and 1 exhaust. All 3 show up on the BIOS main screen. When I go to the Q-fan control page, only Chassis1 and Chassis2 show up. The fan attached to the CPU_OPT header is a 140mm PWM fan and is only running about 600rpm. I would like to increase that speed a little to get better airflow through the chassis. Is there a way to do that or do I have to switch the PWM fan to the Fan2 header? When I had a DC fan attached to CPU-OPT, it ran about 1400rpm. If I say the PWM fan is a DC fan, will that speed it up?
