got to disagree on this one ...
unless maxi has started doing something very very different like rendering 3d graphics or recoding video the processor load shouldn't have changed drastically.
i installed x and now it overheats is a valid reason .... it just started ... means something changes
I don't see how the process count could suddenly start causing overheating
they would cause the machine to slow down ... more than overheating ... processes tend to do a job ... and so their load is variable (look at task manager ... they "blip"
unless it's some sort of malware
a thought ... older machine ... how full is the HDD? ... if it's got less than 20% free it's possible that the swapfile is thrashing the HDD and is overheating ... or maybe it's just failing - either way adding this extra heat to an already hot processor ...
just cause the airways are clear doesn't mean that a dust bunny isn't lurking deeper in the gubbins ...
(think laterally - where is the heat build-up ... you should be able to feel the hotspot)
something like this might help ... but it's not a cure
