In November 2022, EK® – the leading computer water cooling solutions provider – introduced a GPU water block for NVIDIA® GeForce® RTX™ A5000 graphics cards. This enterprise-grade water block is also compatible with RTX A4500 GPUs, which are now added to the water block’s official compatibility list.

EK-Pro GPU WB RTX A5000 incorporates a CNC-machined nickel-plated copper base with a laser-cut stainless-steel top for a robust metal cooling solution, effectively making it a single-slot assembly. 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 dual-slot active and passive air coolers.

EK-Pro GPU WB RTX A5000 – Nickel + Inox Rack water block is purpose-designed for the RTX A5000 graphics cards. It directly cools the GPU, VRAM, and VRM (voltage regulation module) as the cooling liquid is channeled right over these critical areas.

The solution uses an Open Split-Flow cooling engine, characterized by low hydraulic flow restriction, meaning 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.

To improve the graphics card’s stability and protection, the I/O plate is now a part of the water block top. This means 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. The GPU and water block assembly only takes up one single PCIe x16 slot, leaving its surrounding slots available for other add-in cards.

The aesthetic retention backplate improves the card’s looks and structural rigidity while providing passive cooling for the backside PCB VRM area. The cutouts in the water block top and backplate enable the water block and GPU assembly to be fully compatible with the NVIDIA NVLink connector.

The Rack version of this water block features a 45°-angled terminal block at the back, 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. It is also equipped with a side-mounted standoff for GPU brace applications, ensuring secure GPU mounting during transport and movement of the chassis.
