@Ket

Maybe you could help me because of yours good contact with ASRock support.

My cooler Arctic Freezer 13 http://www.arctic.ac/en/p/cooling/cp...13.html?c=2181 has got fan speed rated at 600-2000rpm. When in BIOS I have set CPU Fan speed to Automatic mode, Target CPU temp 60C and level 1 the lowest fan speed is 1700rpm. Why it can't go lower? The highest speed at full LOAD is also above the spec. I saw 2200+ rpm.

Do you think it is BIOS issue?
