EK introduces EK-Pro Line Water Blocks for Enhanced H100 PCIe GPUs

September 22, 2023

EK introduces a high-performance water block designed specifically for NVIDIA H100 Tensor Core PCIe data center GPUs, offering an ultra-compact design, improved compatibility, and efficient cooling for increased performance.

  • Ultra-compact design, taking up just a single PCIe slot compared to the stock 2-slot cooling system
  • Dual-pass cooling engine design, with the coolant passing through two microfin stacks to cool the GPU die, HBM memory stacks, and other components
  • Compatible with the NVIDIA NVLink connector

EK, a leading provider of computer cooling solutions, is introducing a new enterprise-level GPU water block designed specifically for nVidia H100 Tensor Core PCIe data center GPUs. The EK-Pro GPU WB H100 Rack – Ni + Inox is a high-performance water block that offers an ultra-compact design, taking up just a single PCIe slot compared to the stock 2-slot cooling system. This premium water block features a rack-style terminal, reducing assembly height and improving compatibility with various chassis types. It effectively cools the GPU, HBM VRAM, and VRM by channeling cooling liquid directly over these critical components.

The NVIDIA H100 Tensor Core GPUs provide a significant increase in computing power, making them ideal for accelerated computing tasks. They offer up to 30X more performance in certain applications like AI language models and up to 7X performance boost in HPC workloads such as genome sequencing.

The EK-Pro GPU WB H100 Rack – Ni + Inox is specifically designed for professional Liquid Cooling of NVIDIA H100 Tensor Core GPU PCIe Graphics Cards, making it perfect for server rack installations. It seamlessly integrates into standard Full Height Full Width (FHFW) server chassis form factors, serving as a convenient drop-in replacement for both active and passive dual-slot air Coolers.

The product features a Dual-pass cooling engine design, with the coolant passing through two microfin stacks to cool the GPU die, HBM memory stacks, and other components. The fin structure geometry has been optimized to ensure efficient flow distribution even in reversed water flow scenarios.

To enhance stability and protection, the water block’s top includes the I/O plate, replacing the stock I/O shield. This modification improves overall rigidity and stability while offering advantages in compact workstations and server environments with limited space and PCIe slot spacing. The graphics card occupies just a single PCIe x16 slot, freeing up surrounding slots for additional add-in cards.

The water block’s base is precision CNC machined from nickel-plated electrolytic copper, while the top is laser-cut from industry-grade stainless steel. It also includes a screw-in PCIe power connector bracket for secure power connector placement. High-quality EPDM O-rings ensure dependable sealing, and pre-installed brass standoffs simplify the installation process.

An aesthetic retention backplate is included with the water block, improving visual appeal and structural rigidity while providing passive cooling to the backside of the PCB VRM area. The water block and GPU assembly are fully compatible with the NVIDIA NVLink connector.

The EK-Pro GPU WB H100 Rack – Ni + Inox water block features a POM-machined terminal block with two G1/4″ ports for easy integration with EK-Pro QDC kits and manifolds, catering to high-compute-density applications.

For precise compatibility matching, it is recommended to use the EK Cooling Configurator, which undergoes regular updates to mitigate any potential compatibility issues.

The EK-Pro GPU WB H100 Rack – Ni + Inox water block is available for pre-order through the EK Webshop and Partner Reseller Network. It is expected to start shipping in mid-November 2023. The manufacturer-suggested retail price (MSRP) is 302.90€, VAT included.

Technology Explained

GPU: GPU stands for Graphics Processing Unit and is a specialized type of processor designed to handle graphics-intensive tasks. It is used in the computer industry to render images, videos, and 3D graphics. GPUs are used in gaming consoles, PCs, and mobile devices to provide a smooth and immersive gaming experience. They are also used in the medical field to create 3D models of organs and tissues, and in the automotive industry to create virtual prototypes of cars. GPUs are also used in the field of artificial intelligence to process large amounts of data and create complex models. GPUs are becoming increasingly important in the computer industry as they are able to process large amounts of data quickly and efficiently.

Liquid Cooling: Liquid cooling is a technology used to cool down computer components, such as processors, graphics cards, and other components that generate a lot of heat. It works by circulating a liquid coolant, such as water or a special coolant, through a series of pipes and radiators. The liquid absorbs the heat from the components and then dissipates it into the air. This technology is becoming increasingly popular in the computer industry due to its ability to provide more efficient cooling than traditional air cooling methods. Liquid cooling can also be used to overclock components, allowing them to run at higher speeds than their rated speeds. This technology is becoming increasingly popular in the gaming industry, as it allows gamers to get the most out of their hardware.

PCB: Printed Circuit Boards (PCBs) are the backbone of the modern computer industry. They are thin boards made of a non-conductive material, such as fiberglass, with a thin layer of copper on top. This copper layer is etched with a pattern of electrical pathways that connect the various components of a computer together. PCBs are used in almost every electronic device, from computers to cell phones, and are essential for the functioning of these devices. They provide a reliable and efficient way to connect the components of a computer, allowing for faster and more reliable communication between them. The use of PCBs has revolutionized the computer industry, allowing for smaller, faster, and more reliable computers.

PCIe: PCIe (Peripheral Component Interconnect Express) is a high-speed serial computer expansion bus standard for connecting components such as graphics cards, sound cards, and network cards to a motherboard. It is the most widely used interface in the computer industry today, and is used in both desktop and laptop computers. PCIe is capable of providing up to 16 times the bandwidth of the older PCI standard, allowing for faster data transfer speeds and improved performance. It is also used in a variety of other applications, such as storage, networking, and communications. PCIe is an essential component of modern computing, and its applications are only expected to grow in the future.

VRAM: VRAM (Video Random Access Memory) is a type of computer memory used in graphics cards to store image data. It is a high-speed memory that is used to store the image data that is sent to the monitor. It is used in the computer industry to improve the performance of graphics cards and to provide faster access to the image data. VRAM is also used in gaming consoles to provide a more immersive gaming experience. It is also used in virtual reality applications to provide a more realistic experience. VRAM is an important component of the computer industry and is used in many applications.
