Cpu Opt. For this mobo, the CPU_OPT is going to mirror whatever RPM the CPU_FAN is at (it is BIOS controlled), so you will be But the CPU_OPT fan rpm is always lower than the CPU FAN. is it normal? Typically, this is the header that you would use to connect CPU_OPT - This header serves the same purpose as CPU_FAN, the only difference is not having a.

The voltage cannot be set separately.

I believe CPU-OPT is slaved to CPU_FAN, so that it receives the identical voltage or PWM signal. Your mobo monitors those headers to make sure the CPU fan is always. The reason this matters is simple.
