Super Mario

I'm having similar issues. The CPU fans go into full speed. BMC firmware was 0.18.0 but upgraded to 0.19.0 (the latest). Also upgraded the BIOS to the latest version (1.9) and performed a clear CMOS as recommended by an ASRock Tech. What I don't understand is the machine worked fine for 4 months with no changes and then out of the blue this issue occurred. I'm guessing the sensors tolerance change over time and causes this problem. Have also tried restoring the BMC defaults then re-configuring. Works fine for a while and then at any given time the fans will kick into high gear and stay there until a reboot or two. Have emailed ASRock again about an hour ago to see what they can recommend. The other issue is the board is under warranty and the supplier said they would refund or send a replacement but if it's a generic issue with the board it's bound to happen again I would have thought. I have two Intel Xeon E5 2670's installed.
