does pwr_fan works like cpu_fan and cha_fan?

Yes, but it probably has it's very own control settings which may be slightly different than the two.
It's this way on my mobo. But varies depending on manufacture.
I use it for my rear exhaust fan as it usually runs at full and not much need of adjusting.

It also depends if some of them are PWM (4 pin) they control fans using different methods.
