AS Ceramique is some great stuff, but I don't like it at all when I go to remove a heat sink or water block. 99.9% of the time that I use Ceramique it pulls the CPU out of the socket (yes, with the lever closed). It never really bothered me, but I bent the pins on my socket 939 3800+ when I was trying to slide it off the water block that it was stuck to.
It is good stuff when you put a sink on and leave it, but when you change it out 20-30 times a week it causes issues...
Why would it void your warranty? Because you aren't using the thermal paste that they give you? Well, what happens if you lose it (such as in my case)?
as long as there is no trace of the thermal compound it doesnt really matter it will be accepted, both amd's and intel's issues at least for vendors/resellers is that the cpu needs to be totally cleaned (especially amd, intel varies) they can get really picky about that sometimes.
