EK®, the leading liquid cooling gear manufacturer, today announces the availability of two high-performance liquid cooling solutions for the Intel® Xeon® W-3300 processor family optimized for advanced workstation professionals in a single-socket LGA 4189 solution, but also a kit that has enterprise-grade components and tools to build the whole loop to effectively cool the socket LGA 4189 Intel processors.

EK is no stranger to the demanding needs of heavily threaded, I/O intensive workloads across Architecture, Engineering, and Construction, Media and Entertainment, and Artificial Intelligence and Machine Learning industries. The EK-Pro QDC Kit P360 LGA 4189 bundles the EK-Pro CPU Water Block, a 360mm radiator, and enterprise-grade water loop parts. It is designed to cool the most powerful of Intel Xeon W-3300 processors which offer up to 38 cores and 76 threads with Intel Hyper-Threading Technology, up to 64 CPU PCIe Gen 4.0 lanes, and up to 4.0 GHz with Intel® Turbo Boost 2.0 technology, and are rated up to 270W of power. 

EK enables customers to take full advantage of the uncompromised performance offered by the Intel Xeon W-3300 processors by providing a high-performance liquid cooling solution. The EK-Pro CPU WB 4189 is a water block designed to provide sufficient thermal headroom to maximize the performance benefit of Intel Turbo Boost 2.0 Technology while maintaining healthy processor operating temperatures.

“We believe that Intel Xeon W-3375 processor customers, in particular, will very much enjoy our specially designed liquid cooling solution“, said Sandi Logar, Head of Enterprise BU at EK. “With 38 cores, 76 threads, and a maximum boost frequency of 4.0 GHz, the Intel Xeon W-3375 packs an incredible amount of power in a single-socket solution. We wanted to create a liquid cooling solution that enables customers to operate at peak performance unconstrained by any thermal restrictions.”

EK-Pro CPU WB 4189 – Ni + Acetal

This is a dedicated workstation-grade water block that was specifically developed for Intel LGA 4189 processors. The EK-Pro CPU WB 4189 – Ni + Acetal water block features a total of 3 ports. Three ports located on the top are standard G1/4″ threaded and are intended for workstations and taller server racks.

EK-Pro CPU WB 4189 Rack – Ni + Acetal

The EK-Pro CPU WB 4189 Rack Ni + Acetal is a dedicated server-grade water block with 1U rack compatibility specifically developed for Intel®  LGA 4189 processors. Four G1/8″ ports are located split into two sides for easier tube management and ultimate compatibility with low-profile racks.

EK-Pro QDC Kit P360 LGA 4189

This is an enterprise-grade kit that bundles everything a user needs to liquid cool an Intel LGA 4189 socket CPU. It comes with all required custom loop components – radiator, fans, pump, reservoir, manifold, fittings, and tubing. As well as tools to build the loop, utility cables, splitters, thermal paste, and even a filling bottle.
