Hello,
I'll refresh this thread a bit - I replaced the thermal paste on the processor and since then my Mac mini patch 2012 has been raging at tepmperatures between 70 and 100 degrees. What could I have screwed up? The system laughs like crazy, I rebooted and PRAM and SMC and tried with SAFE MODE , changed the paste again and same thing. Do you have any experience with this type of problem?
