Going with the blue and black theme on this board and all of their Extreme boards Intel plastered all of the DZ77GA-70K’s cooling in the colors. The two heatsinks around the CPU socket both are blue anodized aluminum with the larger of the two having a black placard mounted to it showing off the boards name and Extreme moniker. Between the two they will have no trouble keeping this board’s voltage regulation cool, especially the larger heatsink. The other 1/3 of the cooling for the DZ77GA-70K is down near the bottom right. I mentioned this before because of the Intel Extreme skull on it. This is more of a heat spreader than a heatsink yet still does a good job of helping with both cooling and styling on the board. The mesh painted in blue is a nice touch, helping it match the previous extreme board we had in the office while also being unique.
