Fans full speed on Poweredge 1950 II, MOD 3C at 0 rpm

Hello,

 

Just as a brief explanation. My server runs on Ubuntu LTS 18.04. I have had no issues until now. The server is loud, and the fans are running at 100%. Upon checking ipmi-sensors, I saw that fan MOD 3C is at 0 rpm. Visually, this fan is running.I have replaced the fan module and cleared the ESM logs, yet fan MOD 3C is being reported at 0 rpm. There is no visual damage to the pins, or anything on the board as it has not been touched.

 

Any suggestions as to what the fault could be?

Hello

If you are using validated hardware and have swapped with a known good fan then the issue is with the connector. Fans will either connect to a fan assembly or directly to the system board. You will need to replace whichever you have to replace the connector.

I would drain flea power before replacing any hardware. This will clear volatile memory and cause a full reload of all hardware. If it is an issue of the iDRAC having an issue of updating the RPM then that should fix it.
