5. Thermal Specifications

The high performance devices installed on the Intel® FPGA PAC N3000 require server based forced air cooling to maintain proper operating temperature. This section provides air flow requirements for the Intel® FPGA PAC N3000. Sufficient air flow keeps the Intel® Arria® 10 GT FPGA junction temperature below 95 °C. Each data point corresponds to minimum airflow (Y-axis) through the card for a corresponding card inlet temperature (X-axis).

Table 9.  Thermal Terms and Descriptions
Term Description
Cubic Feet per Minute (CFM) Volumetric airflow rate, in cubic feet per minute, of air passing through the PCIe faceplate of the Intel® FPGA PAC N3000.

FPGA Junction Temperature

Local Ambient temperature. Temperature of forced air as it enters the Intel® FPGA PAC N3000.
Note: In many systems, this is higher than the room ambient due to heating affects of chassis components.
The Intel® FPGA PAC N3000 uses a passive heatsink. The server must provide sufficient forced airflow to keep the FPGA within the following operating conditions:

Parameter Value
Intel® Arria® 10 FPGA Thermal Design Power ≤69 W
Intel® FPGA PAC N3000 Thermal Design Power ≤ 126 W
Recommended FPGA Maximum Operating Temperature 95 °C
FPGA TJ-MAX / Thermal protection shutdown 100 °C
