I have an ASRock H81M-ITX and have just concluded a very frustrating day of intel stock cooler CPU fan speed control diagnosis.
Symptoms of the problem sound similar to those reported in this thread.
Erratic control of fan speed from whatever control source (one of the BIOS stock profiles, BIOS custom profile, SpeedFan 4.51 beta 4). A hunting behaviour of the speed. Fan wouldn't stay at a constant non-max speed.

No problem (physically identical) Intel cooler: Foxconn E97379-001
