Just to tell you, Kents clock like crap on 680i motherboards
Even with Ln2/DICE. It will be hard to get to 3.2Ghz. And to apply the thermal paste, just put a nice amount in the middle, spread it around evenly with a credit card, or a plastic bad around your finger and seat the heatsink. It doesnt matter if it is 4 core 6 core or 8 core, etc. Intel uses an IHS (integrated heatspreader) that they solder onto the cores for optimal heat transfer. Just put a like a dot the 1/2 the size of a grain of rice. That should do it. Make sure you have nice even pressure on your cpu, don't worry about cracking the core, cuz you won't.
