Hello All,
Full disclosure, I am not a Truenas user, I am an UNRaid user. I have searched everywhere and even posted on UNRaid and haven't received an answer yet. I am hoping, I could get some help and understanding.
I have a Supermicro X10DRU-i+ , with stock fans (nidec ultraflo v80e12bga5-57) they are rated for 9500rpm (see pic below)

This particular board has Fans 1-8, there are no FanA or FanB. I have my CPU fans on Fan 4, and Fan 6. UNRaid has a IMPI plugin that I tried and it seemed to work for Fans 1-4, but Fans 7, 8 in particular are ramped up to Full speed, oh which is another thing, I don't have standard mode in my IPMI webpage. I just have Optimal, full, and I forget the other.
Ideally I would like to get the fans down to around 3000-3500rpms. I may be able to live with that, but even at optimal it's over 4000rpms and unfortunately, my den where I work is my server room. lol
So here is where I am lost I've seen this
ipmitool raw 0x30 0x70 0x66 0x01 0x00 0x32 (which would be 50%) that would be 4750rpms
If I entered this;
ipmitool raw 0x30 0x70 0x66 0x01 0x00 0x23 (would this be 37%) that would give me around 3515rpms
If the above is true, how would I write that into a script so that when UNRaid boots it sees the changes, and I do apologize for asking here and no one knows, but at least do I have the right concept?
Thank you all in advance.
