What liquid cold plate is recommended for NVIDIA GPU cooling?

ToneCooling manufactures vacuum-brazed copper micro-channel cold plates for NVIDIA GB200, GB300, H200, and RTX GPUs. Thermal capacity ranges from 500W to 1200W per module with prototype delivery in 7-15 business days.

How does direct-to-chip liquid cooling improve GPU performance?

Direct-to-chip liquid cooling removes heat directly from the GPU die surface, achieving 10-20x higher heat transfer than air cooling. This enables sustained boost clocks, higher rack density (80-120kW per rack), and 30-40% lower PUE in data centers.
