H170M-ITX/DL CPU fan control

Hello there,

First post here, and it seems I'm not the only one!

Background: I bought my H170M PRO4S last December, and temporarily put 2 non-PWM fans into my chassis because, well, that's all I had. Recently bought 2 Arctic PWM fans but I've noticed they were LOUD!!! A download of A-Tune proved me right - both over 1400rpm, even with the CPU at relative idle.

The fan adjustment, to put it bluntly - doesn't work. You can move the points to wherever you like, but they ain't gonna make a blind bit of difference.

So...I bring you a workaround- it can be adjusted in BIOS, using a similar graphics. You need to go to Advanced View, and it's either under Tools, or over looking options. It's called EZ-FAN. I've changed mine, saved, rebooted and both my chassis fans are now sat at 500rpm, much more like it!

I've uninstalled A-Tune because it makes no difference. Oh - I'm on Windows 10 x64. I've got an i5 6600.

Hope this helps someone!!

All the best,
Greg

My fan is small too ...

Yes, we can see Intel has used fans from different manufactures, whose power requirements vary from 0.14A to 0.60A, including Delta, Fujikura, Nidec, and Foxxcon. At least two of those manufactures are known for the quality of their products.

The power usage of the fan means nothing relative to the PWM fan speed control.

AGAIN I ask those of you in this thread, is the CPU cooler you have with your Skylake CPU the one on the left in the picture in my post above?!?!?!

Please let me know, Thanks!!!

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 . 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.)

Fan can be manufactured by many companies.
