For example I'm happily using Fan Control on my 2010 Mac Mini, but as you can see I have the Lower Threshold set fairly low and the Fan will start ramping up pretty fast if it goes over 51C.
I also use SMCFanControl on my early intel iMac and both can be somewhat confusing if not used or removed properly.
1. None of the temps look like a problem.
3. Temps are lower than normal, fan higher.
Might try SmcFanControl, or the other one as mentioned.
