this stuff really is not good. I used it myself on a lapped IHS and a copper based HSF and even though I did notice 1 or 2'c drops in temps after a week of testing I went to remove it to find that it had eaten into the copper and could not be removed. I ended up having to completely relap both copper surfaces to get rid of it.

Also, if you want to see what it does to aluminum, watch this video I made:
