Subject: Fan control on H170M Pro4

I'd be interested in the answer for this too. Just built a new PC for a friend with the H170M-Pro4 mainboard and put in an i5-6500 CPU. The stock CPU fan ran at near 1900 RPM between 50-100% PWM and stopped completely below 50%. I suspected a faulty cooler. Replaced the cooler with one from an i5-4590 that I had laying around and I can now adjust fan speeds between 800 and 1900 RPM with 40% to 100% PWM respectively.

I was looking for information on the PWM_CFG1 header when I found this post.
