Full-IHS Coverage for AMD EPYC and Threadripper
The EK-Pro CPU WB sTR - Nickel + Acetal is a server-grade water block designed for AMD EPYC and Ryzen Threadripper processors, offering three G1/4" threaded ports. It covers the entire integrated heat spreader (IHS), enhancing cooling with a dense micro-fin structure.
Crafted with CNC-machined POM Acetal and laser-cut stainless steel, it features a pure copper base with nickel electroplating. Its pre-assembled mounting mechanism ensures easy and error-free installation on SocketTR4 and AMD's server-type Socket SP3 motherboards. Ideal for desktop PCs, workstations, and server racks.
Three design decisions worth calling out
Dense Micro-Fin Full-IHS Coverage
Covers the entire integrated heat spreader surface to maximize thermal contact area, ensuring even heat extraction across all chiplets of multi-die AMD processors.
Pre-Assembled Error-Preventing Mount
The pre-assembled mounting mechanism aligns directly with SocketTR4 and SP3 mounting holes for tool-guided, error-free installation without risk of uneven clamping force.
Nickel-Plated Copper + Stainless Steel
Pure copper base with nickel electroplating combined with laser-cut stainless steel components ensures long-term reliability in continuously operating server and workstation environments.
