CPU water blocks,
for every socket worth running.
CPU water blocks for Intel Xeon and AMD EPYC, Threadripper, and Ryzen processors. Workstation form factor uses top-mounted G1/4″ ports for tower builds. 1U rack form drops to side-mounted G1/8″ ports for vertical clearance inside rack chassis. Nickel-plated copper base, POM Acetal top, EPDM O-rings throughout.

Two terminal layouts, one cold-plate engine.
Workstation
Top-mount G1/4″ ports
Top-terminal design with two G1/4″ threaded ports. Designed for tower and desk-side workstation builds where vertical clearance is generous and routing flexibility matters. Compatible with EK-Pro QDC kits and standard fittings throughout the catalogue.
Mounts directly under the chassis fan or pump-res header
Server rack
Side-mount G1/8″ ports
Rack-style terminal routes plumbing horizontally for 1U chassis clearance. Two G1/8″ side-mounted ports keep the block envelope flat against the motherboard. Pairs with EK-Pro QDC kits for single-block serviceability inside a populated rack chassis.
Compatible with 1U rack chassis at standard board height
