CPU cooling

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.

EK-Pro CPU water block — sTR Nickel + Acetal
Form factors

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

Socket not on the list?

The catalogue covers the platforms our customers actually deploy. If you are working with a specific socket variant, multi-CPU board, or a chassis constraint that affects block clearance, tell us what's in the build - we'll confirm compatibility or design a variant.
