I'm looking for the cause and/or fix of an issue when during start up of the DH61AG board the fans go full speed as they normally do but stay at full speed rather than slowing. In the BIOS the PC status the fan speeds are negative, and temperatures and voltages are zero.
Here's a poorly taken photo:
The chance of this happening is rare, but I have reproduced it 9 times. It seems to be a BIOS issue since it has been reported on multiple boards, with different CPUs, RAM, HDDs and fans. I have seen it happen with a blank HDD, on Win 7, from a cold start, after stressing the system, and after normal use. I don't have the slightest clue as to what the cause might be, like I said earlier it happens randomly, not often and a tell-tale sign in that the fans stay at max speed. I let it load into windows once instead of going to the BIOS and ran HWMonitor, which picked up voltages, temps, and fan speeds.
Intel got back to us saying it was a motherboard defect that was in a batch of motherboards, replacement boards were given to us.
Later Intel gave us a BIOS update. After updating the BIOS and thorough testing, the issue did not reoccur. Check for BIOS update and if it isn't there, contact Intel for update.
