If water-cooling a CPU is a good idea, then using a liquid as a cooling medium for both the CPU and the power delivery circuitry on the motherboard must be better. This line of thinking led to the development of custom water blocks for a number of Intel X99 and Z270 motherboards from Asus, Gigabyte, and MSI. EK Waterblocks is at it again with the EK-FB ASUS C6H RGB Monoblock. The company calls this unit the first waterblock for an AMD Ryzen mobo—in this case, for Asus' high-end ROG Crosshair VI Hero.
Like every other EK waterblock we can think of, the model for the Crosshair VI Hero is CNC-machined from a block of copper and then coated with corrosion-resistant nickel plating. The top is made from transparent acrylic. EK says the cold plate has been redesigned to allow improved mechanical contact with the integrated heat spreader on AMD's Ryzen processors and seventh-generation APUs. The block covers both the CPU and the power delivery section of the motherboard and uses a high-flow design that the manufacturer says should allow compatibility with weak fluid pumps.
Being custom-machined exclusively for use with a single Asus model, the waterblock has a four-pin RGB LED header compatible with the motherboard manufacturer's Aura Sync software utility. The included RGB LED-lit strip cover can be removed to change its orientation or to replace it with a custom part.
