Well, after all the talk of misapplied thermal paste on the MBP, I started to worry that maybe my Core Solo could be suffering from the same problem. I downloaded "Core Duo Temp", which actually registered my Solos temp, and at idle, I was running at around 62-63 C. Under load, running HandBrake or folding with 100% CPU use, I was at 78 - 79 degrees C. That's insane. I know, I know, the processor can take it, yadda yadda yadda, but I can't! I decided to open up the Mini and investigate, and while you can't tell from the pictures, the thermal paste is well-applied, but completely dried up. Feels like it burnt off, pretty much: I scrapped off as much as I could, and applied some Arctic Silver on the Core Solo: I've been running it with 100% load for the past hour now, and I've maxed out at 75 degrees C. Not much of a result, really, but it's a little better, and a little's better than nothing! Just thought you guys would like to know!
