EK-Pro Pump Reservoir Manifold X3 D5 - Acetal is a 3-in-1 product that acts as a pump, reservoir, and manifold. The X3 in the name designates the number of components it can directly connect as a manifold, and D5 indicates a single D5 pump pushing the liquid around the loop.

It can act as a regular pump-reservoir combo, be used like a manifold, or, practically, as a distribution plate, even though its aesthetics vastly differ from most distro plates.
This combo unit can be mounted to the case in many different ways. EK-Pro Pump Reservoir Manifold X3 D5 has M4 screw threads on the side opposite to ports and on the backside, allowing for plenty of mounting options, multiplied by the bracket with 120mm fan mounting hole spacing (105mm). Eight (8) G1/4" ports are available, of which two act as dedicated fill and drain ports.

This combo unit comes with a powerful yet silent PWM-controlled D5 pump. The goal was to make a product with enough power to offer excellent reliability and outstanding performance with multiple blocks and radiators while keeping the noise down to a minimum. The D5 pump has been updated with the latest G3 (Generation 3) variant and comes with a SATA power connector, following the latest PC industry trend to decrease the use of 4-pin Molex cables.
EK-Pro Pump Reservoir Manifold X3 D5 – Acetal comes with a drain port and a Quick Disconnect Coupling/Fitting and tubing for the user to be able to drain their system directly out of the case without the need for any other tools. You simply slide on the part of the QDC with the tubing onto the other half of the QDC installed on the combo unit and effortlessly drain the reservoir. Using the QDC is entirely optional but brings many QoL benefits.

Most of this combo unit is made of durable Black POM acetal, with the addition of a stainless steel plate that goes over the front of the combo and has a sliver opened for the see-through acrylic window.
The pump is held by an acetal holder. Coolant is sealed by high-quality O-rings.

EK-Pro GPU WB A100 80GB Rack - Nickel + Inox is a high-performance full-cover water block for the NVIDIA® A100 80GB PCIe data center graphics card. It was specifically engineered to make the entire GPU and water block assembly as thin as possible, effectively allowing it to consume only a single PCIe slot width-wise. The water block is equipped with a rack-style terminal, considerably reducing the assembly height and increasing the chassis compatibility. The EK-Pro Rack GPU water blocks conform to 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.

By spanning the entire PCB, the water block directly cools the GPU, VRAM, and VRM (voltage regulation module) as cooling liquid is channeled directly over these critical areas.
EK-Pro GPU WB A100 80GB Rack – Nickel + Inox water blocks use an Open Split-Flow cooling engine design which 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 and servers. The jet plate and fin structure geometry have been optimized to provide even flow distribution with minimal losses and optimal performances even when used in reversed water flow scenarios.

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 sealing is ensured by high-quality EPDM O-Rings. The brass standoffs are already pre-installed and allow for a safe and easy installation procedure.

For added stability and protection of the graphics card, the I/O plate is now an integral part of the water block top itself, which 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 is at a premium. This design enables the card only to consume a single PCIe x16 slot, leaving the surrounding slots available for other add-in cards.

The EK-Pro GPU WB A100 80GB Rack water block features a POM-machined terminal block at the back and features two G1/4” ports, enabling easy integration with EK-Pro QDC kits and manifolds for high compute density applications.
