i'm currently using a volcano 8 and its gotten to the point where the dust is effecting the performance of my heatsink (i think)... current temps on idle is 64C. it wasn't like this before. My question is, is the Bergquist 225U interface material (came with the heatsink) useable again after i take off the heatsink? if not, is it possible to take this off with regular alcohol so i can apply a fresh coat of AS3? thx in advance for the help.
