i was told to use isopropyl rubbing alcohol to remove the thermal stuff that came on the bottom of my heatsink. I will be applying arctic silver 5 but before i do i would like to know how much i have to clean the heatsink? i have removed almost all traces of the thermal stuff but if i hold it at certain angles, i can see the outline of where the thermal pad was. does that mean htere are traces of thermal stuff left and i have to clean more?
if not how much tolerance is there for old thermal stuff left behind?
