I just started having problems with my Mid 2011 Mac Mini — it's fan is continously on although the computer temperature is relatively low and not a lot of CPU is being used. I'm very nervous about this because my last Mac Mini died due to overheating issues.
I realize this may be a common problem, but I specifically would like to know about two keys that appear when I run iStats:
$ istats scan

Done scanning keys.`
As you can see everything is a somewhat normal temperature except for the TCPG and TC0G keys, which are close to 100 degrees Celsius. Would anyone be able to tell me what these keys are, and how I could address this issue?

The reason why I'm getting really high readings is because I'm using a third-party SSD which doesn't have Apple's thermal detectors included.
