I've been using Artic Silver 5 on CPU and I was going to switch to IC diamond. When I apply the Artic Silver 5 I usually apply a line down the center then lock the fan/heatsink in place. I let the pressure of the heatsink spread the paste and prevent air bubbles. I had read though that IC diamond is different. You put a pea size blob in the center of the CPU then turn on the computer without the heatsink for 10 minutes. This allows liquid in the paste to evaporate. Then you lock the heatsink in place and your done. My concern comes with turning on the computer without a heatsink. I really don't like that and it goes against everything I have ever learned, that is never run a computer without a fan/heatsink. So do you really need to do that and is it safe? This would be for an I5 2500k.
