I ran the thermal calibration - it failed saying the CPUs (both of them) have exceeded the maximum temperature. The machine is totally clean - no liquid, no stains, no residue anywhere. The seals seem solid. I don't believe that it's been "leaking" as in dripping out. Could it evaporate

Hi all! Wouldn't it make sense for CPU A to be hotter than CPU B? I don't know much about hardware, but if Mac OS X (or any PowerPC OS acutally) uses threading, isn't it possible that frequently used threads are allocated to CPU A? Or, maybe more sensible, CPU A just happens to get most threads?

Hi all, I'm looking for some ideas on how to address a problem with my Quad G5 (late 2005). Here's the sequence of events: 1) I took my QuadG5 out to the garage one nice warm Saturday and used compressed air to blow out all the dust. Yes, this may have been a bad idea... 2) Since then
