EAI-I251 vs EAI-I252 - which is fanless, and how do max operating temp and Jetson module support differ?

Question

Rapidflare · Accepted Answer

**The EAI-I252 is the fanless one.** Here's how the two Lanner Edge AI Box PCs compare on cooling, thermal limits, and Jetson module support:

| Attribute | EAI-I251 | EAI-I252 |
|---|---|---|
| Cooling | Fan-cooled | Fanless |
| Max operating temp | 70 °C | 60 °C |
| Min operating temp | -40 °C | -40 °C |
| Supported Jetson families | Jetson AGX Orin | Jetson AGX Orin and Jetson AGX Orin Industrial |

Key differences,

- **Cooling:** The EAI-I251 is a fan-cooled appliance while the EAI-I252 is fanless.
- **Max operating temp:** The EAI-I251 goes up to 70 °C; the EAI-I252 tops out at 60 °C. Both share the same -40 °C minimum, and both temperature ranges depend on power mode (the EAI-I252's also depends on SKU or module).
- **Jetson module support:** The EAI-I251 supports the Jetson AGX Orin family, while the EAI-I252 supports both Jetson AGX Orin and Jetson AGX Orin Industrial.

In short: choose the EAI-I251 if you need the higher 70 °C ceiling with active cooling, and the EAI-I252 if you need a fanless design with the option of the AGX Orin Industrial module.
