The EK-Pro CPU WB sTR Rack - Nickel + Acetal is a dedicated server grade water block with 1U chassis compatibility that is tailor-made for AMD® EPYC™ and AMD® Ryzen™ Threadripper™ processors. 1U rack compatibility is achieved through the use of two G1/4”-threaded side ports that enable a smaller vertical footprint. 

Aside from 1U compatibility, the primary goal in designing the new EK-Pro CPU WB sTR Rack - Nickel + Acetal water block was to cover the entire IHS of HEDT AMD® EPYC™ and AMD® Ryzen Threadripper processors and to improve the cooling performance. A dense micro-fin structure that counts 91 wide grooves fully covers the CPU dies that are located below the IHS so they are cooled more effectively.

The top is made from CNC-machined durable POM Acetal. Every EK-Pro CPU WB sTR Rack water block comes with a precisely machined copper base (sometimes referred to as ‘cold plate’) which is made from the purest copper available on the market and is treated with nickel electroplating.

EK-Pro CPU WB sTR Rack - Nickel + Acetal comes with a pre-assembled error-preventing mounting mechanism that is installed directly onto the SocketTR4 mounting holes. The result is a perfect installation that results in optimal performance every time. This also means the water block is out of the box compatible with AMD’s server type Socket SP3 motherboards. With such a mounting solution, the user does not need to remove the motherboard from the case and so has a hassle-free installation procedure of the new CPU.

It’s recommended that users follow the EK-Pro CPU WB sTR Rack - Nickel + Acetal water block installation manual for the suggested method of thermal grease application for the best-expected results.
