A100 SXM cold plate
Configuration reviewPlan a direct-to-chip cooling assembly for an existing HGX A100 tray. GPU WORLD reviews the accelerator revision, mounting stack and rack loop before specifying a plate.
Fit and compatibility
- Identify the SXM4 module capacity, HGX baseboard part number and revision, chassis and GPU count. The A100 PCIe liquid variant uses a different card assembly.
- Verify the contact drawing for the GPU and high-bandwidth memory, the retention pattern, and the space above the module for fittings and hose bends.
Scope of supply
- Specify the cold plate, OEM-approved thermal interface stack, retention hardware and port orientation for the selected tray.
- For a tray conversion, agree the branch manifold, hose assemblies, matched quick disconnects and any change to the existing CDU interface.
Operating conditions
- NVIDIA lists 400 W TDP for standard A100 80 GB SXM and up to 500 W for the specific HGX A100 80 GB Custom Thermal Solution SKU. Use the confirmed module and its configured power for the heat budget.
- Obtain the plate thermal and pressure-drop curves at the approved coolant conditions. Confirm that the existing pump meets branch flow and that the baseboard components outside the liquid loop retain airflow.
Acceptance checks
- Check plate clearance and mounting against the approved drawing, then record the leak test and branch flow with the tray installed.
- Run the agreed workload and record accelerator and memory temperatures, throttling indicators and coolant inlet and return temperatures.
