Re: heatsink removal
Use a Xylene based cleaner like GooOff - the odor is strong so use in a well ventilated area. Its best on those hard to remove gunk from thermal pads. For best results, dampen a cloth with goo off and place it on top of the cpu die only and apply light pressure. After a couple of minutes, wipe the cpu clean. Then use high purity isopropyl alcohol using q-tips to remove any impurities.
