My system is a 1ghz athlon tbird.
decided to clean out my heatsink, because I haven't done it since I installed the thing, which has been about 2.5 years now.
Just for shits and giggles, took some temperature readings before cleaning.
51c when idleing.
removed a cubic inch of dust and hair from the cpu (cats). a cubic freakin inch! and this is a stock amd heatsink, not some monster thermaltake or something.
Cleaned up, rebooted. my idle temp was now 46c.
dropped 5 degrees just by cleaning out the dust. heh.
Decided to push the sucker a bit, worse comes to worst I use my laptop till I replace a burnt chip.
idle at 1.1ghz was 51, same as 1ghz was before cleaning.
Pushed it up to 1.2ghz, fastest my Mobo will let me go, haven't broken 60c on a load test.
i just got a free processor upgrade!
So how did you precisely measure the amount of dust? :-p
I should OC mine sometime, but I reall don't need it. 1.4 GHZ XP (or 1.7 as they call it) and I can so far run everything gamewise at 1600x1200 with all detail turned up with nary a hitch.
And really, the best benchmark is gaming, because I don't think Seti@Home is something I'll notice changes in.
