Overview

1U-Compatible Cooling for AMD EPYC and Threadripper

The EK-Pro CPU WB sTR Rack - Nickel + Acetal is a server-grade water block designed for 1U chassis compatibility, specifically for AMD EPYC and AMD Ryzen Threadripper processors. Its compact design utilizes two G1/4"-threaded side ports for vertical space efficiency.

Featuring a dense micro-fin structure, it covers the entire CPU Integrated Heat Spreader (IHS) for improved cooling performance. Crafted with a CNC-machined POM Acetal top and a pure copper base with nickel electroplating, it ensures durability and efficient heat transfer. With a pre-assembled mounting mechanism, installation onto SocketTR4 mounting holes is seamless.

1U-Compatible Cooling for AMD EPYC and Threadripper

Key Engineering

Three design decisions worth calling out

Dense Micro-Fin Structure

Covers the entire CPU IHS surface area for uniform heat extraction across the full die footprint of AMD EPYC and Threadripper processors.

1U Chassis Compatible

Side-mounted G1/4" ports minimize vertical height, enabling installation in 1U rack chassis without compromising loop connectivity or flow.

CNC-Machined Nickel-Plated Copper

Pure copper base with nickel electroplating ensures long-term corrosion resistance and thermal conductivity. CNC-machined POM Acetal top provides chemical and mechanical durability.
