EK-Quantum 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-Quantum 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 primary goal in designing the new EK-Quantum Velocity sTR4 water block was to fully cover the entire IHS of HEDT AMD® Ryzen Threadripper processors and to improve the cooling performance. A dense micro-fin structure that counts 91 wide grooves fully cover the CPU dies that are located below the IHS so they are cooled more effectively.

EK-Velocity sTR4 water block

The top is made from CNC machined glass-like Acrylic material. Every EK-Quantum 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-Quantum 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.

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