Today we've done something we don't usually do. We tested a watercooler that was specifically designed for motherboards. There haven't been a lot of reviews on ocaholic regarding custom watercooling components, which is one thing we want to change during this year. In this case we've had a closer look at EK's custom block for ASRock's Z77 Extreme11 high-end motherboard and it turns out that it makes quite some sense to use this watercooler over the standard coolers, especially in a high-end rig.
