What Is an H200 Liquid Cooling Cold Plate Set?
An H200 liquid cooling cold plate set is a group of copper cold plates that mount directly on the eight GPUs and the NVSwitch devices of an H200 (SXM5) baseboard and carry their heat into a shared coolant loop. Coolant enters through a manifold, passes through each plate and returns to the rack manifold and CDU, so the server can run its full GPU load without relying on airflow.

How Is the H200 Cold Plate Set Tested?
- Leak test, 100% of units: helium leak test or pressure test, with acceptance criteria per project
- Proof / burst pressure: tested to the project requirement
- Thermal cycling: per IEC 60068-2-14
- Bonded-joint inspection: ultrasonic C-scan per ASTM E2375
- Documentation: RoHS / REACH declarations on request
What Should You Check Before Integrating an H200 Cold Plate Set?
- Flow and pressure budget: confirm that your rack manifold and CDU can supply 8.0 L/min per set at 18.5 kPa (±20%).
- Inlet temperature: the reference point is 38 °C pure water; a warmer inlet or a glycol mix changes surface temperature and must be checked.
- Connectors and routing: quick-disconnect type and hose routing are confirmed per project.
- System pressure: the set is rated to 0.8 MPa maximum operating pressure.
How Does the H200 Set Compare with ToneCooling’s Other AI Server Kits?
ToneCooling supplies four standard AI server cold plate kits, each to its own datasheet: GB300 4G+2C, GB200, H200 and H100. Compare them side by side on the AI server liquid cooling kits page or the liquid cold plates overview. Product listing: H200 liquid cooling plate.
