EK-FB ASUS C5F-Z is a complete water cooling solution for ASUS® Crosshair V Formula(-Z) motherboard. This waterblock directly cools AMD® 990FX northbridge chip and power regulation (VRM / MOSFETs) module. It is medium-high to high flow water block design that can be easily used with systems using weaker water pumps.

Base of the waterblock is made of nickel plated electrolytic copper while the top is made of quality POM Acetal material and covered with laser cut stainless steel plate. The sealing is performed by quality rubber gaskets.


Water block is mounted with enclosed M2.5x4 DIN7985 screws and PVC washers. Preinstalled  2.1mm nickel plated brass screw-in standoffs allow for easy installation.

Enclosed thermal pad is used on voltage regulator module to improve cooling performance of the waterblock. On the northbridge please use any electrically non-conductive thermal grease, e.g. Gelid GC-Extreme.

The southbridge chip SB950 remains cooled by factory (ASUS®) provided heat-sink.

This product is intent to be run without the backplates. The stock backplates are made of steel anyway and don’t have practically any cooling surface. Their only job is to ensure even contact of the factory flimsy heat-pipe cooling system with the MOSFETs. Because the EK-FB ASUS C5F-Z waterblock is made out of hard electrolytic copper there is no need for such backplates.

- Due to immense variety of fittings/barbs available on market and no prescribed standards, we guarantee compatibility only for connectors bought from our web site.
