For anyone out there running Proxmox (or, I suppose, any Debian-powered OS), a question:
Can you recommend any software for controlling the fan RPMs that lets me get the speed lower than 20 percent of full speed on some of the case fans?
I’ve built my server into a Supermicro CSE-835, and all my drives are low-powered SSDs
I’ve got active cooling on both the CPU and VRM; they idle in the low 30s and low 40s respectively. RAM is in the mid-to-low 30s at idle as well. The VRM is the hottest thing in the system, from what I can tell, and it’s got about 40 C of thermal headroom before I need to start worrying about it.
Problem: The overpowered Supermicro front intake fans are loud, even at their current 20 percent setting. I suspect these fans–which are meant to cool passively cooled Xeons, etc.–are entirely overkill for my setup at 20 percent of their max RPM. I’d like to test them at 15 percent or even 10 percent, but the IMPI’s manual fan control interface won’t let me go lower than 20 percent.
The person I bought this rig from was using Unraid, and set the fan speeds using a add-on Unraid module. I don’t see anything like that for Proxmox, though fancontrol
(which I have never used) is available in the repo.
The seller told me he used the Unraid module to set the fans to their lowest speed, which achieved an acceptable low volume for working near the server in an office room and kept everything cool enough–and he was using spinning HDDs, which would have run hotter than my setup.
Is fancontrol
the way to go? If it is, is there a good tutorial somewhere?
Or should I be looking at something else?
EDIT (2022 04 23 @ 2040 US Central Time): I’ve just realized that I should probably be using ipmitool
for this, but up-thread it looks like that’s not working for some people.
Has anyone actually gotten it to work?
(I hate messing with the fans. I still don’t understand what the difference is between open loop and closed loop tables. I’m using the open loop for the CPU and have everything else on manual, but I have no idea if that’s actually the way to go or not w/r/t open vs. closed.)
