I think there's been some work on the fan speen in recent BIOS/iLO versions. AFAIK HP currently recommend you put the controller in AHCI mode for use with linux nowadays. I haven't seen versions of their Linux fake-raid driver for a few years now. I think it's been retired. Another issue I've seen people report as a reason for the increased fan speed were hdds which didn't report temperature properly to the controller so the controller didn't know whether the drives were cool or hot. What BIOS/iLO versions are you running?

My BIOS is J06 04/04/2019, iLO firmware 2.70 May 07 2019. Latest B120i driver was released at 30 Apr 2020. I don't think it's retired yet, but they don't support RHEL 8, so I'm forced to stay on RHEL 7. I can see that iLO firmware is not latest, but it's BIOS who's responsible for fan speed control and I think that I'm running latest BIOS. That's not really about BIOS versions. When HDD runs under B120i fakeraid mode, server is aware about HDD temperature which is displayed in iLO. As long as this temperature is low, fans stay low. When HDD runs under AHCI mode, server is not aware about HDD temperature anymore, so it uses high fan speed to ensure that cooling is good enough even if drives are hot. That's how I interpret this whole situation.

  > Latest B120i driver was released at 30 Apr 2020. I don't think it's retired yet Ok, I might have misunderstood the info posted at: http://downloads.linux.hpe.com/SDR/project/ubuntu-hpdsa/ http://downloads.linux.hpe.com/SDR/project/ubuntu-hpdsa/ which states: "NOTICE! The hpdsa driver is no longer being developed past the versions indicated. Do not upgrade the Ubuntu kernel or try to use this binary driver with Xenial. If you have a B-series Smart Array, it is advised to use the Linux md (software raid) driver, or upgrade to an H or P series hardware-based host bus adapter." I thought the hpdsa driver was the same across distros, not unique to Ubuntu. Based on what you're telling me it seems that only the Ubuntu version was discontinued.
