I am going to very blunt here.
There is only ONE right way to apply thermal paste...
A dot, no bigger than a grain of cooked white rice, placed in the center of the seated Proc. It will be spread by you seating and securing the heatsink..
Temps are best When it is done this way.
It had to be said...
Sorry!!
Yes. Most will do it this way. I have always had very good temps by spreading a very thin layer on both cpu and hsf. Those that are reading this I'm not suggesting my way is the best way. Just saying my temps have always been very very good. But most users will do the rice thing.
