You are quite right that it can be a problem to get rid of, but nothing like as bad as those "thermal patches" Acetone (nail varnish remover) can also be useful.

And very good advice: ONLY USE SOLVENTS IN A WELL VENTILATED SPACE

Spot on, too much and it doesn't work properly. Worse still, if you use silver compond it is highly electrically conductive, so if it leaks out onto the MoBo you are in big trouble! The silver compound is actually being replaced by a more thermally efficient and far less electrically conductive material.........I have just had some advisories but no samples as yet.

Good question. What CPU are we talking, what case & MoBo as well? I agree that 65C seems on the high side, I would personally not like to see much above 50. But, Professor Teile old chap,
you have not told us how long the machine was powered up; and whether this was an idle or load reading?
