Prelude

When I installed to Dell PowerEdge G13 10G Ethernet Adapter - Intel Original X710/XL710, server increase fan speed. R330 and R730xd is affected.

Root Cause

When unknown PCI card installed (unknown for PowerEdge) in LifeCycle Log you can see message:

New PCI card(s) have been detected in the system that may require additional airflow. Fan speeds may have changed to add additional cooling to the cards.

And Recommended Action:

Changing default fan response to PCIe cards should be done with appropriate understanding of the PCIe cooling needs of the cards present in the system. If the automatic cooling response is insufficient, additional cooling can be added by one of the following methods. 1) From iDRAC Web GUI, click Hardware -> Fans -> Setup, then from the fan speed offset drop-down list appropriately select the cooling level needed or set the minimum fan speed to a custom value. 2) From F2 System Setup, select iDRAC Settings -> Thermal, and set a higher fan speed from the fan speed offset or minimum fan speed. 3) For RACADM commands run "racadm help system.thermalsettings". If a lower fan speed is required, contact your service provider for the appropriate IPMI commands to reduce the default fan speed response for new PCIe cards.

Solution

Get Third-Party PCIe Card Default Cooling Response Logic current state:

ipmitool -I lanplus -U root -P calvin -H 192.168.0.120 raw 0x30 0xce 0x01 0x16 0x05 0x00 0x00 0x00

Response like below means Enabled:

16 05 00 00 00 05 00 00 00 00

Set Third-Party PCIe Card Default Cooling Response Logic to Disabled:

ipmitool -I lanplus -U root -P calvin -H 192.168.0.120 raw 0x30 0xce 0x00 0x16 0x05 0x00 0x00 0x00 0x05 0x00 0x01 0x00 0x00

Response like below means Disabled:

16 05 00 00 00 05 00 01 00 00

Result

Now PowerEdge slow down from 87% to 25%.
