Yes.. I recall seeing things like this on older processors.. in fact, here's a website from a guy who made these. I dunno if he still does or what -http://www.agaweb.com/coolcpu/build.htm
I'm not sure I'd like to try something like that on my AMD processor... even with the silicon application. I honestly have no clue what it could do to the chip itself... certainly is a question worth asking.
