EK-Velocity sTR4 is the 3rd generation of CPU water blocks that are tailor-made for AMD® Ryzen™ Threadripper™ processors. They come with a pre-assembled, error-preventing mounting mechanism. The primary goal in designing the new EK-Velocity sTR4 water block was to cover the entire IHS of HEDT AMD® Ryzen Threadripper processors and to improve performance over the previous generation of sTR4 water blocks.

The top is made from CNC machined POM Acetal. Every EK-Velocity sTR4 water block comes with a precisely machined copper base (sometimes referred to as ‘cold plate’) which is made from purest copper available on the market and is treated with nickel electroplating.

EK-Velocity sTR4 comes with a pre-assembled error-preventing mounting mechanism that is installed directly onto the SocketTR4 mounting holes. The result is a perfect installation which 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.

This product is compatible with popular RGB sync technologies from all major motherboard manufacturers. The arrow marking on the 3-pin LED connector is to be aligned with the +5V marking on the A-RGB(D_RGB) header. You can easily remove the LED strip cover which is mounted with two screws to replace the LED strip with some other type of LED strip.

It’s recommended that users follow the EK-Velocity sTR4 water block installation manual for the suggested method of thermal grease application for the best-expected results.
