So seems to be an improvement when in BIOS (1.60) I switch CPU Fan from Auto to 4-Pin.
With my Custom setting in BIOS I see it now spinning at ~1000RPM and when doing CPU burn test RPMs increase as expected.
Few notes of caution though A-Tunning CPU Fan control seems to be screwing things and fan again goes to 2000RPM, so better don't use it. I had to go to BIOS change settings "on/off" save and power cycle to get back normal fan control.
ASRock put a note somewhere on BIOS 1.60 download page with HUGE LETTERS that CPU Fan setting should be changed to 4-Pin.
