One of the leading brands in PC custom liquid cooling, EK waterblocks, will be expanding their AM4 socket monoblock portfolio by making a monoblock for one of the most popular and well known motherboards on the platform, the ASUS ROG Crosshair VI Hero, Crosshair VI Extreme and Crosshair VII Hero motherboards.

The EK-FB ASUS C6H RGB Monoblock – Acetal has an integrated 12V 4-pin RGB LED strip which makes it compatible with ASUS Aura Sync, thus offering a full lighting customization experience with so far my favorite motherboard RGB solution.
