Trying to follow these instructions: How to control fan speed?

sensors-detect added this module: coretemp

I get this error when runnting pwmconfig: /usr/sbin/pwmconfig: There are no pwm-capable sensor modules installed

I am using this mainboard, having connected two PWM fans to it: https://www.supermicro.com/products/motherboard/atom/A2SDi-4C-HLN4F.cfm

Update: I contacted supermicro and they said that there was no official support for this on Linux, but IPMI is supported. With that being said, if someone were to discover a hack or similar to do it, please answer here.

  • Do you have fan control enabled in your BIOS settings? Are you sure the fans have speed control? What does sudo sensors-detect give you? – pbhj Apr 22 '18 at 17:33

The issue is that your board has IPMI management which has different tooling. You can control anything you like... as long as you do it over a network.

So connect up the IPMI network port (I'd just loop it into one of your extra ports as a server), and then install IPMIView to connect. (I haven't done this on mine yet).

Perhaps you can't change much in there, and need to use the ipmitool command line directly. That works without connecting the LAN port... but I can't be bothered learning it at this stage.

In summary, not much of an answer, but has keywords that should help somebody else find their way and elaborate on this
