NVIDIA CMP 170HX 8GB GPU Water Block – Liquid Cooling for AI / CUDA Compute

LIQUID COOLING WATER BLOCK FOR NVIDIA CMP 170HX 8GB

Convert your NVIDIA CMP 170HX 8GB from its original passive air-cooled configuration to a compact liquid-cooled AI compute GPU.

This water block is intended for CMP 170HX systems used for AI inference, CUDA compute, machine learning, GPU servers, homelab AI systems, and other continuous compute workloads where improved thermal management and higher GPU density are desired.

Designed for CMP 170HX 8GB AI Systems

The CMP 170HX uses NVIDIA’s GA100 GPU architecture and has become increasingly popular for AI and CUDA applications using community-developed driver/unlock solutions.

The original CMP 170HX cooler is designed around high-volume server airflow. This liquid-cooling solution provides an alternative for users building quieter or higher-density AI systems with their own pump, radiator, reservoir, and cooling loop.

High-Performance Copper Cold Plate

According to the manufacturer’s specification, the GPU water block features:

• T2 copper base construction
• Electroplated surface treatment
• Approximately 401 W/m·K thermal conductivity
• 0.3 mm internal coolant channels
• 44 coolant channels
• Approximately 10,787.6 mm² coolant-channel area

The fine-channel copper design increases the heat-transfer surface area for efficient removal of heat from the GPU assembly.

Ideal for Multi-GPU AI Servers

Liquid cooling can be particularly useful when operating multiple CMP 170HX cards in the same system.

Suitable applications include:

• AI inference servers
• Local LLM systems
• CUDA compute
• Machine learning
• GPU compute clusters
• Multi-GPU AI workstations
• Homelab AI servers
• Continuous 24/7 compute workloads

Removing the large original passive heatsink can also make it easier to design compact, high-density multi-GPU configurations.

Approximate Water Block Dimensions

Manufacturer drawing specifies approximately:

Length: 265 mm
Width: 134.2 mm
Water-block thickness: approximately 19.6 mm

Please review the listing photos and your system configuration before ordering.

Cooling Loop Required

This listing is for the GPU water block / cooling assembly only unless otherwise specifically shown or stated.

A complete liquid-cooling system normally requires:

• Water pump
• Radiator
• Reservoir
• Tubing
• Compatible fittings
• Coolant
• Fans for the radiator

These components may be supplied separately depending on your installation.

Installation

Installation requires removal of the original CMP 170HX cooling assembly and correct installation of the water block, thermal pads, thermal compound, and mounting hardware.

Professional installation is recommended.

The manufacturer’s specification includes thermal pads, thermal compound and mounting hardware as part of the cooling assembly specification; please check the photos and package contents for the exact accessories included with your order.

Leak Tested

The manufacturer’s production specification includes a leak test of the cooling system to verify that the assembly does not leak before leaving the factory.

Important Compatibility Notice
