I got thenAMD A8-6600k and the fan has little grey squares checkerboard ing the bottom. Is this thermal paste? Or is that just the design? Do I need to reapply it because it is just little squares?

It's the normal factory supplied paste. It performs reasonably well, not as well as some of the aftermarket stuff from say arctic or gelid. The checker pattern is just how it is applied, probably to get a more uniform spread and then more uniform distribution when doing the processor break-in.

Can you post a picture? All the AMD's (and Intel's) I've seen have been a solid piece of thermal paste no checkerboards.

I've built a few light duty machines with the newer kaveri apu's, they all had the checkerboard paste.

Gotcha. I haven't seen any of the kaveri's yet. Still seems a little strange though .

I imagine it increased efficiency, it's probably not the easiest to get a machine to apply an even coat of such thick material, it probably aids in whatever termination/separation technique is used to break the supply in the paste applicator, like a pastry frosting applicator and a knife. So the grid pattern probably allows for a bit thicker layer which then thins out when the heatsink is locked down.

It's consistency changes to regular paste after it is heated up for the first time.

Oh yeah, I know that, I was referring to when it was being manufactured potentially.
