Hi, I own a H170 Pro4/Hyper motherboard and it comes with 3 CHA_FAN headers as stated in the technical specifications. The problem is, only CHA_FAN1 and CHA_FAN2 have adjustable speed in the BIOS, while the RPM speed of CHA_FAN3 can only be seen.

What's worse is that the speed of CHA_FAN2 does not change and is not affected no matter what percentage % I've set in the HWMonitor in BIOS, even with 0% the fan on CHA_FAN2 will run at full speed.
I've tried different fans for all of the headers, 3-pin and 4-pin does not make any difference. I can only change the speed of the fan that is connected to CHA_FAN1. CHA_FAN2 and CHA_FAN3 only work as a power supply to the fans, and I'm not sure what's the purpose of having CHA_FAN2 adjustable in the BIOS.
