sadly i havent got a camera to show but i thought id share anyway since it impressed me.

earlyer today i started running core temp at the same time as folding. I noticed that the temps were a tab too high, so i desided to clean out the cpu heat sink....

when i got the fan off, there was no visible slots between the metal plates off the cooler, and what impressed me was the fact i managed to pull off all the dust as one neat blanket. it looked like a cloth 15cm by 15cm made of dust.

then when i loaded up the system again to see new temps everything is 15C cooler

RESULT

goes to show that sometimes a little cleaning is in order not new parts
