EK, the leading computer cooling solutions provider, now offers enterprise-grade GPU water blocks for NVIDIA RTX A5500 graphics cards. These new water blocks incorporate a CNC-machined nickel-plated copper base with a laser-cut stainless-steel top for a robust liquid cooling solution, effectively making it a single-slot assembly. Two options are available, one specialized for rack mounts and another for regular PC-case use.
EK-Pro GPU WB RTX A5500 Rack – Nickel + Inox
EK-Pro GPU WB RTX A5500 Rack – Nickel + Inox is a purpose-designed water block that enables you to have professionally liquid-cooled RTX A5500 GPUs that can fit in a server rack. This water block directly cools the GPU, VRAM, and VRM (voltage regulation module) as the cooling liquid is channeled right over these critical areas. The EK-Pro Rack GPU water blocks fit the standard Full Height Full Width (FHFW) server chassis form factor, making them a drop-in replacement for active and passive dual-slot air coolers.
At the back, this version of the EK-Pro A5500 GPU water block features a 45°-angled terminal block made of POM and machined stainless steel. It has two G1/4” ports, allowing easy integration with EK-Pro QDC kits and manifolds for high compute-density applications. Additionally, the water block is equipped with a side-mounted standoff for GPU brace applications, ensuring secure GPU mounting during transport and movement of the chassis.
It is recommended that you refer to the EK Cooling Configurator for a precise compatibility match. EK checks for compatible graphics cards and updates the configurator database daily.

Cooling Engine
The solution uses an Open Split-Flow cooling engine design that proved to be a superior solution for GPU water blocks. It is characterized by low hydraulic flow restriction, which means it can be used with weaker water pumps or pumps running on low-speed settings and still achieve top performance. The lowered coolant flow requirement makes it an ideal solution for multi-GPU workstations. The jet plate and fin structure geometry have been optimized to provide consistent flow distribution with minimal losses and optimal performances, even when used in reversed water flow scenarios.
Machining of EK-Pro Water Blocks
The base of the block is CNC-machined out of nickel-plated electrolytic copper, while the top is laser-cut out of industry-grade stainless steel. The top plate possesses a screw-in PCIe power connector bracket to securely hold the power connector once fully assembled. High-quality EPDM O-Rings ensure that the sealing and the brass standoffs are pre-installed to enable a safe and easy installation procedure.
Special PCIe Expansion Bracket
To improve the graphics card’s stability and protection, the I/O plate is now a part of the water block top. This means that the block replaces the stock I/O shield and adds more sturdiness to the whole assembly. The integrated single-slot I/O plate also benefits more compact workstation and server environments, where space and PCIe slot spacing are at a premium. This design lets the card consume only a single PCIe x16 slot, leaving its surrounding slots available for other add-in cards.
Backplate (Included) and NVLink-Compatibility
The water block comes with an included aesthetic retention backplate that improves your graphics card’s looks and structural rigidity while providing passive cooling to the backside of the PCB VRM area. The cutouts in the water block top and backplate enable the entire water block and GPU assembly to be fully compatible with the NVIDIA NVLink connector.
