I was looking at my fan options on the H370-F and there does not seem to be any setting in BIOS or AsusAI for the 2nd (CPU_OPT) CPU fan header. Is it just a "splitter" off the main CPU_FAN header?!?

If so, what will happen if a DC fan is on the Opt connector while the CPU_FAN is set for PWM for the main CPU fan?!?

Hi s..

I believe that the CPU FAN and Opt Fan headers work together.. intended mainly for a push-pull fan setup... so in essence, function like a splitter...

Is CPU_OPT an independand header, or just a splitter?
