Don't know right off the top of my head but I'd start with DigiKey (most likely http://www.digikey.com/) and Mouser (also guessing http://www.mouser.com/). Not sure that you could find the info on web pages, but at least you'd get their 800-number. If that failed I'd start bugging my local electronics distributors and watching EE Times and EDN more closely. I smeared the silicon grease on my CPU's. It can be messy but I don't do that many CPU's and "one size fits all" with the grease. One thing about the gasket that might rule it out for a CPU: when you *bolt* a transistor to a heat sink you have a fair bit of pressure to deform a gasket to the surfaces. You don't have that pressure between a big expensive delicate chip and heatsink. I once bought a 486 fan and heatsink that had a gasket, but who knows if anybody'd ever bothered to determine if that gasket was an insulator or conductor?
