Hi Jonway,

Below suggested accessories is already installed in Intel LWF2208IR848505 server.

Accessory: AWFCOPRODUCTBKT: High Air flow Air Duct Bracket Kit & A2UL16RISER2: 2-slot PCIe* Riser card.

Please suggest else what could be the issue in intel server.

    1. Confirm that you are running at maximum fan speed

    2. Does the card shutdown even at idling? if no, you may want to check with your workload developer how to reduce the workload.

    Hi Jonway,

    Below is the attached output from supermicro server when immediately run the command after booted to OS for your reference.

    But after OS booted later on the output is different.

    I think this further confirmed that you dont have enough airflow.

    When you first booted into OS, the card is still working but very near to shutdown temperature.

    (12) FPGA Die Temperature : 96.50 Celsius

    After a while, when the temperature exceed 100C, it will shutdown, and you wont get any reading.

    The card is fine and working as expected. The problem is that you dont have enough airflow to the card. You will need to check with the server vendor on how to improve airflow to the pcie slots devices.

    some questions:

    1. how to confirm that you are running at maximum fan speed or modify it?

    2. the fan referred to here is the fan of pac board or the fan or server machine?

    thanks very much

    hi @ahaa

    There is no fan on the pac card. It is passively cooled.

    Some server vendors fan speed is changed in the BIOS and some are changed via the server BMC (maybe there are more other ways), you will need to check with the server vendor to know what speed you are running at, and how to change it.
