Only think I would say is look up other thermal pastes, Arctic silver 5 was good years ago, but there are some nice compounds for a similar price that work as well or better and don't have a burn in time like the silver does. Arctic MX4 I think is one of them, Toms has done a nice round up of compunds here: http://www.tomshardware.com/reviews/thermal-paste-performance-benchmark,3616.html
