Product: EliteDesk 800 G1 USDT
Operating System: Microsoft Windows 10 (64-bit)

I have a EliteDesk 800 G1 USDT where the fan is running at full speed. 

 

Looking into the bios, under Power > Thermal > Fan Idle Mode shows ??????

 

I cannot adjust this, I have reset bios to factory defaults, but no change. Even on a cold boot the chassis (exhaust) fan runs at full speed.

 

The cpu (inlet fan) also seems to run at high speeds. I know this setting is to adjust the minimum fan speed but I simply cannot adjust it. 

 

In the O/S (Win10 Pro) I have installed SpeedFan, but it doesn't see/detect any of the two fans.

 

Removing the chassis (exhaust) fan, the bios complains and says chassis/exhaust fan not found so it know it's there.

 

Any experts out there know how I can resolve this?
