ProLiant ML350 G9 with excessive fan noise during normal server operation

[Chris_Cygnet_IT]

I have a ProLiant ML350 Gen9 which the fans come on regularly making a lot of noise. There are no failed fans (four fans installed) and the temperature is below the threshold levels.

There are two Intel(R) Xeon(R) CPU E5-2609 v3 @ 1.90GHz installed

The Firmware versions are as follows:
HP Smart Array P440ar Controller    7.00
System ROM P92 v1.40 (05/06/2015)
Redundant System ROM P92 v1.40 (05/06/2015)
Power Management Controller Firmware    1.0.9
Power Management Controller FW Bootloader    1.0
System Programmable Logic Device Version 0x13
SAS Programmable Logic Device Version 0x3
Server Platform Services (SPS) Firmware 3.0.6.267.1
iLO 2.70 5/07/2019

The server started making the noise in August and I have attempted to track down the cause both on the server and online in your forums without much success thus far.

Hi,

1. I see the ILO4 FW version is latest 2.70 but the BIOS FW is quit old , kindly update the BIOS FW from the link below & monitor the fan noise.
