Heat Dissipation Requirements
The Atlas 300I inference card (model 3000) is used in an active heat dissipation environment with fans. It supports bidirectional air intake and air exhaust. The air volume must meet the heat dissipation requirements.

- The minimum required air volume refers to the air volume through the heat sink of the card.
- The ambient temperature at the heat sink inlet refers to the mean temperature at the air intake vent of the module.
- The required air volume here is just a recommended value. The air volume and incoming flow temperature provided by different systems for the Atlas 300I inference card (model 3000) may vary, and are determined according to the actual test results.
- When the Atlas 300I inference card (model 3000) is powered on, the system needs to provide basic heat dissipation capabilities. The minimum required air volume is 3.0 CFM.
