CPU Fan Speed Supermicro X11SPL-F

[AlexTheTrue]

Hi!

I have a problem with the fan speed (loudness).
It is a Supermicro X11SPL-F Board, with the Supermicro SNK-P0070APS4 active heatsink cooler.
After booting a fresh installed truenas core, the behaviour is:
FAN1 plug (upper right) the speed ramps up every 10 seconds for some seconds
FAN2 plug (middle right, upper connector) the speed ramps up to full speed and stays there

Any idea, how i can set the fan speed to a normal (noise) level?
I did not find any EFI settings for fan speeds.
And it´s just a Xeon 4208, which is pretty cool and does not require lots of air.

Have a look at these scripts, and setting suitable low limits for your fans through ipmitool:

Script: Hybrid CPU & HD Fan Zone Controller

So, I've been working on something. Update 2024-03-15: I've ported the controller to SCALE and created a github repository: https://github.com/mrstux/hybrid_fan_control # This script is designed to control both the CPU and HD fans in a Supermicro X10 based system according to both # the CPU...

Fan Scripts for Supermicro Boards Using PID Logic

Since motherboards have no way to access drive temperatures, they can’t really regulate them. The fan control scripts presented here read and respond to both drive and CPU temperatures. Such scripts are MUCH better than the control built into...
