Fan Control Guide: Intel Z270 Motherboard Edition (Page 6)

ASRock Z270 Fan Control


ASRock's manual is very good at defining each fan header, and we can also see that they are using hybrid headers too. We don't know current ratings, other than the CPU header is rated 1A. ASRock does provide a healthy number of headers.

ASRock Z270 UEFI Offering


ASRock's UEFI has built in fan calibration; you just need to enter Fan Tuning, FAN-Tastic Tuning is a GUI for fan control. Once it's done testing it spits out minimal duty cycles for your fans, it picked up 20% for the same fan calibrated on some other motherboards.


ASRock's offering both a GUI and manual entry control for fan tuning in their UEFI. They also have a live feed of the data points on the graph. Their manual entry offers more settings such as step up/down times, temperature source, and control mode. The GUI is more for visualizing the data points.

ASRock Z270 Software Offering


ASRock offers FAN-Tastic Tuning in Windows as well inside the A-Tuning software. You can calibrate your fans using the FAN Test. You can only choose a different temperature source when tuning non-CPU fan headers through the software. I did tune the Noctua fan, and at 40% it resulted in 885RPMs, which is exceptionally close to the GBT/ASUS readings, which were almost identical. We did notice that the other calibrations didn't give us any numbers under 40%, and that is because PWM specification states that minimum RPM should be 30% of maximum RPM (606 here), which is just under the 30% mark. So it seems that ASRock is just giving us extra information.
