Once you have a working config (my full config is posted at the end of this article), you can test things out by running watch sensors in one terminal window and then fancontrol in another. You might decide it's easier to configure these values later and hit the "just save" button. That process will look something like this:Īt the end of the pwmconfig wizard you'll be asked to set which temp probe correlates to which fan. Now it's time to run pwmconfig and follow the prompts on the screen to test the various PWM values and how they interact with the RPM values of your fans. Then run: sensors-detectįollow the prompts and you should see the fan speeds and temp probe readings like this: ~]# sensors Next, ensure that fancontrol and lm_sensors are installed (this varies per distro so no instructions here). Configurationįirst you'll need to connect the Commander Pro to a USB header on your motherboard, hook up some fans and at least one temperature probe. I created a tiny Arch VM to run automatically on boot under ESXI and passed the USB device through to the guest for this purpose which uses 256mb of RAM. You will need a kernel of at least 5.9 or later. That changes today!Ĭonfiguration of this device is quite straightforward but is a little time consuming. This sleek black box can be had for $40-75, I was fortunate enough to get mine for $40 because it seemed like a good idea before I realised it didn't support Linux and had to run a Windows VM for control. BIG thanks to the developer Marius Zachmann who made this happen. This device used to be Windows only so it was a really lovely surprise to find that this driver shipped last year. Well my friends, I'm pleased to report that last summer the Corsair Commander Pro received native Linux kernel driver support in the 5.9 release.
I can tune out a constant white noise pretty easily but the one thing that is unacceptable are fan notes that change wildly or oscillate. Relying on the built-in motherboard headers on server grade motherboards to reliably control fans with Linux has been a crapshoot since forever.
