Cooling on the UD3H is bare minimum when compared to any other Z77 board, but of course this is a budget board. The blue for the cooling is the only blue on the board, with everything else fully blacked out. There is a small blue anodized heatsink covering all of the boards voltage regulation. The UD3H lacks a heatsink above the CPU socket like we would normally see. Down toward the bottom there is another blue anodized aluminum heatsink cooling the chipset.
