Sorry I've been busy... Thanks so much for posting your result, glad that worked for you!!
Questions, it looks like you ran the Fan Test, and the result is in your screen shot, right?
The Fan Test result is better of course, but still looks not quite right, for several reasons.
The 10% power fan speed is higher than I've ever seen for a PWM fan, or any type of fan. The fan speeds from 10% to 40% are easily within the the normal speed variations of a PC fan with a constant, non-changing voltage applied. All fan's show a variation in their RPM at any constant voltage, and that variation can be +/- 10% or more.
Frankly, between 10% and 40% you are not getting any change in fan speed. If the fan's maximum speed were 2000RPM, 19RPM difference between 10% and 40% fan power is 1 RPM short of a 1% change in speed. So no change in speed worth anything.
There is obviously something wrong with the fan speed control software, or the fans. Here are two examples of my CPU cooler's fans, the first one a PWM fan, the second a three pin fan, both are completely different fans than the Intel stock CPU cooler fans.
This is a Cryorig QF120 Performance PWM fan, RPM range 600 - 2200 RPM:
![]()
This is a Noctua NF-P14, maximum speed of 1200 RPM:
![]()
Notice how low in speed the Noctua fan can run. The Cryorig fan speeds match its specs very well.
I know you guys know something is wrong, and I agree with you. It seems ASRock is looking into this and responding.
I searched for a picture of the Skylake stock cooler, and found this. It's called a TS15A, the larger one on the left side![Shocked]( "Shocked")
. Is this what you got with your Skylake processors:

(BTW, ANY and ALL Intel CPU coolers provided with their processors from Sandy and Ivy Bridge (socket 1155) through Haswell (socket 1150) and now Skylake (1151) will FIT and WORK FINE on a Skylake board.)
