Arctic Silver (currently version 3) is the industries best. Actually it was for like over 2 yeras. Now its pretty much tied with "evergreen" something. I forgot what that was called. Any was ACS is some really good stuff and its tested to be about 2-3 degrees lower then other TIMS. Just make sure you don't get it on capicitors and stuff like that and you should be fine.

oh ya and.........squeeze gently lol. If you sqeeze too hard you'll have a smooth streem of acs all over the place.
