Aqua Computer 21821 computer cooling system part/accessory Water block by Aqua Computer

CPU water block for sTRX4, perfectly adapted to the revised chip layout of the third generation of Threadripper CPUs.

Base part with micro structure
All components of the water block are CNC machined at Aqua Computer's headquarters in Germany. The copper base features a huge area microstructure (51 x 45 mm), which is machined with the finest spacing manufactured by Aqua Computer (less than 0.2 mm). This microstructure is one of the reasons for the exceptional cooling performance of the cuplex kryos NEXT sTRX4 FC.
The contact area to the CPU is machined with increased precision and then polished for perfect heat transfer. Additionally, the copper base is finished with nickel plating.

Full size CPU coverage
The "FC" token stands for "Full Cover" - the copper base of the water black covers the whole CPU. Heat generation is not distributed evenly within the CPU, thermal energy is concentrated in certain areas. Specially designed for the third processor generation, an optimized internal coolant flow ensures maximum cooling performance in the areas where thermal energy is generated.

Retention system
The cuplex kryos NEXT sTRX4 FC retention system ensures easy installation. Recessed springs and screws with mechanical stop
result in optimum clamping force and even force distribution.
For optimum performance, outstanding thermal compound is included. A syringe with 1 gram of Thermal Grizzly Kryonaut is included, complete with plastic spatula. This compound has a high thermal conductivity and spreads out thin and evenly between CPU and water block due to its low viscosity.

Material combination
Base material: Copper, nickel plated
Housing material: Acetal, black
