Title:

2010 MacMini Thermal Sensor location

Text:

I have the above-noted Mac Mini. All works well except the fan runs at 5000+ RPM all the time
 
I suspect the thermal sensor is either bad or connected incorrectly to the system board.
 
My questions is: Which of the 2 possible locations on the logic board are used if there is only a single HD in the system? Or, does it even matter?
 
I bought this unit used, and there were other minor details about it that make me think whoever added/ replaced the HD was not careful in reassembly of the Mini - which is why I wonder about the possible misplaced sensor.
 
Thanks in advance!

=== Update (01/25/2016) ===

The images would have made more sense, if, when I opened up the Mini, there had been 2 thermal sensors connected. As it was, there was only one and it was connected to the left connector (farthest from the RAM slots. )

I moved it over to the right slot and it's settled right down,

Thanks for the quick reply
