8.1. Thermal Cooling Requirements

System airflow to the Intel® FPGA PAC D5005 must be provided to keep the FPGA junction temperature below its 100 °C maximum specification. The temperature of the QSFP modules must also meet the module vendor’s specification, typically 70 °C or 85 °C. The following table shows the airflow requirement for the Intel® FPGA PAC D5005 during operation.

Linear Feet per Minute (LFM)

Air velocity is calculated by dividing the volumetric flow rate by the cross-sectional area of the flow passage.


The measured ambient temperature locally surrounding the FPGA. The ambient temperature should be measured just upstream of the heatsink.
