I just updated the bios on an MSI H61M and the fan went crazy. I had to go into the bios and change the fan setting from auto to some specific targets. I set the CPU target to 50C and set the max fan speed to about 50 percent. The CPU runs about 39C and the fan silent. I did not try for higher temps or fan speeds but I expect those would be fine as well, it was automatic that seemed to send the fan speed out of control with the new bios. The bios upgrade was required to get my new GPU recognized. The MSI board would not post with an HD 7790 with the original bios that the factory installed.
This was a prebuilt Micro Center Sandy Bridge and had never really misbehaved before.
