This is what I've used for '060:

I used "THERMAL TAPE" (Sekisui) solution. Yes, it SUCKS compared to any thermal paste, but you really aren't trying to cool some 3GHz monster as someone here said.
I really would AVOID any permanent GLUE. One day you'll find a better heatsink and regret gluing old one!
