Me too. After all the stuff I heard about crushed and chipped cores I got a nonconductive shim from crazypc. I don't know if it made it easier for me to install the hsf, but it certainly gave me more confidence that I wasn't going to destroy the core. I needed all the confidence I could get after I jizzed (sorry, no other word fits) Arctic Silver all over my bridges and other places it shouldn't be. I did a lousy job squeezing a pinhead full of that stuff out. Rubbing alcohol is a wonderful thing.
