I have a tube of Arctic Silver 5. And my CPU needs to be re pasted, its got old dried up and cracked paste atm, not very high quality at all, so im going to clean the old stuff and put something better in. My question is this. Is it ok to put a pea sized amount in the centre of the cpu, then seat the heatsink and screw it in, or is it really necessary to spread it thinly and risk making a big mess? Ive read the entire thing doesnt have to be coated, and in other places ive read it has to be spread thinly across the entire thing. So before i even attempt this i want to make sure whatever i do will be the correct way, id like to do it once and not have to worry for a few years after.
