Bykski GPU Block For Nvidia H100 80G / H800 80G, High Heat Resistance Material POM + Full Metal Construction, With Backplate Full Cover GPU Water Cooling Cooler Radiator Block, N-H100-80G-X

The Bykski full-cover GPU water block for the H100 replaces the stock blower or open-air cooler with a direct-contact copper cold plate pressed against every major heat source on the card — GPU die, VRAM modules, and VRMs in a single pass.

Running local AI inference continuously pushes GDDR6X VRAM toward the 92°C throttle threshold within minutes on air. Water cooling keeps VRAM well below that ceiling, sustaining full memory bandwidth through long Ollama sessions, ComfyUI queues, and overnight batch jobs.

Drop the loop noise below 30 dBA — quiet enough for a bedroom or shared home office even under 24/7 AI load. Material: nickel-plated copper cold plate, acrylic/POM top. Fittings: G1/4 thread. Ships worldwide.
