I recently purchased a Mini late 2009. I also increased the RAM to 4GB and replaced the stock hard drive with a 500GB unit. Problem now is that the fan (left fan runs constant at 7,400 RPM, right fan not running at all, case ambient temp is 33C and room is 72F with good ventilation) tends to run constantly (loud). I installed Temperature Monitor and can see why the fan is constantly running (the machine thinks it is about to melt on just the one sensor):

I find it very hard to believe the values from this sensor as the differential compared to the other sensors is extreme and all the other sensors would seem to agree with each other. Perhaps I need to move the sensor (it is affixed directly to the rear of the replacement drive and maybe is on a hot spot?).

Powermac G4 Dual 1Ghz Quicksilver, Mac OS X (10.5.7), 3.5 Tb harddrive space, 1.25G RAM.
