Fans Runs With Full Speed With Big Noise Lenovo Desktop ThinkCentre M73 (10B5-A00VAX)

Hi All,

 

I had some motherboard problem so I replaced the motherboard with the same model as the desktop was under warranty. Since then, the chasis fan runs on the maximum speed creating noise like a car engine. I tried updating the Bios , tried replacing the CMOS battery but nothing works . Kindly please share your thoughts and ideas so to help me out on this issue.

Purely a guess:  The temp sensor (if this model has one), not plugged in or plugged in reversed?
