The thermal threshold definitions are described in the " NVIDIA BlueField-3 Networking Platforms Electrical and Thermal Specifications " document. You can access the document either by logging into NVOnline or by contacting your NVIDIA representative.


This section applies to 900-9D3C6-00CV-DA0 only, 900-9D3C6-00CV-GA0 is shipped without a heatsink.

The heatsink is attached to the DPU by three screws to dissipate the heat from the IC.
The DPU IC has a thermal shutdown safety mechanism that automatically shuts down the DPU in cases of high-temperature events, improper thermal coupling, or heatsink removal.

Refer to the below table for heatsink details per card configuration. For the required airflow (LFM) per OPN, please refer to Specifications.
