Product: HP 280 G2 MT

Hello team,

 

Another issue that seems to be a faulty motherboard, I just wanted to be sure first. On a desktop, the CPU fan fails to be detected, therefore it does not work. The weird thing with this case is that, if I switch positions with the chassis fan, they both work smooth! On this case, the chassis fan works on high load (makes some sound), but it bypasses the error.

 

I have to notice that the CPU fan has 4 pins and i assume that there is an issue on the 4th pin, or a short circuit on the motherboard. I have switched CPU fan from a same PC, but the results are totally the same.

 

Any ideas?
