I have an S1200BTL motherboard on a p4304xxsfcn chassis. I've updated the BIOS, FRU, BMC to the latests but the chassis fan is still running full speed. The BIOS only has an option to change the altitude. The fan speed is set to auto and is not configurable.
I've booted to the Intel Deployment Assistant and updated through that as well but still no change.
What would cause the fan to be running full speed? I have two systems showing the same issue.
