recommend me a new thermal paste. I've been using Arctic Ceramique so far, but it seems the last batch I applied has dried up and gone bad, apparently killing my GTX480 on the process. Can't say for sure yet as I'm still tearing down my loop and haven't got the time to put the reference cooler back on and test yet. The stuff had rubberized and was coming of the gpu chip in flakes like old paint. Needs to be nonconductive, so no silvery stuff.
