> The automatic system cooling response for third-party cards provisions airflow based on common industry PCIe requirements, regulating the inlet air to the card to a maximum of 55°C. The algorithm also approximates airflow in linear foot per minute (LFM) for the card based on card power delivery expectations for the slot (not actual card power consumption) and sets fan speeds to meet that LFM expectation. Since the airflow delivery is based on limited information from the third-party card, it is possible that this estimated airflow delivery may result in overcooling or undercooling of the card. Therefore, Dell EMC provides airflow customization for third-party PCIe adapters installed in PowerEdge platforms.
You need to use their RACADM interface to update the minimum LFM for your card.
