Hi all, I just bought H170M PRO4 and settings up everything.
I use i5-6600 and stock cooler with latest BIOS 1.9, my cpu cooler works nicely.
Problem is CHA_FAN1 and CHA_FAN2, I decided that I have to connect PWM fan which has 4 pin connector and purchaed at once 2 pcs of PWM type fan from market. It comes with 4pin connector and PWM capable fan.
However it does not work at all, no matter what I change settings when I connect to my mobo.
Not spin at all, and I tested with FAN-Tastic fan test, CPU fan works nicely but all CHA_FAN1 and FAN2, no RPM data, it only shows '0' values.
So I disassemble my fan from case, and put 12V directly on PIN1 and PIN2 which is GND and DC12V, and it spins nicely. So, I think my fan is not faulty but mobo does not control my fan at all.
Anybody has same CHA_FAN1 and FAN2 issue with PWM fan?
Hope I can get some great information here.
Thanks in advance!
