i use ocz's stuff and that works great for me. just dont be surprised if you dont get immediate results...it takes some time for the paste to "break in". after a few weeks my temps dropped an additional 3 or 4 degrees idle and load. as for applying it, online instructions will tell you to put a dab the size of a grain of rice directly in the middle. as long as your heatsink is fastened tightly there shouldnt be any air pockets in there. good luck
