Np, glad to help. But don't be so sure on only AsRock, MSI is as good if not better in terms of bios fan control, as it also has Switchable headers like Asus, right now my AsRock Z370 Taichi only has 2 switchable, the rest are pwm, so if you are only using PWM fans both mobos are the same, but for someone wanting to use the inclued fans on their case, and maybe wait to upgrade them... then MSI would be my recommendation for its flexibility, i think AsRock is moving on to switchable headers, this is the first that i seen abandoning the autodetect, my guess is next gen will be all switchable. If you ask me which i prefer, honestly i think both are good, now with Taichi, AsRock is bringing a lot of value to the high end segment (not as super high end like rampage), and MSI has been great, their gaming series are very well made, even their low end are really nice mobos, for every new build i try to look what both offer and decide upon my needs knowing that bios fan control is the same (as long as you use PWM fans).
Talking about MSI, i manage to do the testing on doing 0% PWM on the MSI Z370 Gaming M5, again on Bequiets Silentwings3 120mm PWM, and yes it can stop the fans on 0% pwm and start them with load and stop them once the temps go down below the temp breakpoint, so in essence both work the same on bios fan control. Check the bottom for pics.
I did check and the fans spin up on powerup then spins down once the bios loads, also open the case when i was running prime95 to see if the fans spin up and i can confirm they do, and they also spin down when the temp goes lower than 50C.
Sadly i cant do the test on CPU_FAN header, my fans on both builds are Thermalright TY147A, by design you cant stop them, under 0% pwm they spin at 300rpms. To do the test i would need to dissamble the build to reach where the CPU fan header is, maybe when i clean it up, but for now know that any header can (without the confirmation on the CPU_FAN, my guess is that it will run as the others).
