It goes through different PWM signals from 0% to 100% in 5% steps.
#Arch fancontrol manual
This script takes manual control of a fan header. If you are interested in doing some experiments, I have a test script that does manual control for a fan header and prints the fan speeds: The manufacturer advertises that fan model as 1600 rpm.
I have two fans of the exact same model where one of them does about 1650 rpm and the other one about 1550rpm. This would be 17% off compared to 1500 rpm. That 1250 rpm you are seeing sounds a bit extreme. Something like 5% different speed is normal. In my experience, the fan speed can be off a bit in practice compared to what the manufacturer is promising. Maybe it's actually a 1200rpm fan and is labelled wrong? I would guess there's a mistake somewhere and it's not really a 1500rpm fan.

I just want to validate how to spin the fan up to 1500 RPM at high temps and why it doesn't seem to do it.ĮDIT2: Might have had a wrong source, BIOS has a test button to set it to 100% and there it caps out at 1250 RPM it says. I saw some forum posts that said one has to disable BIOS-smart-fan, but I'd like to keep the bios fan curves if possible. states how to set it up, but doesn't mention how these systems usually work. Sooo, how does fan speed control actually work on archlinux? Do I have to set it up myself? Does it actually override the BIOS fan control? and the CPU hits 92C sensors claims that fan2(I can only guess it's the CPU fan, it matches CPU temp changes closest as far as I can tell) only runs at 1250RPM. However, when I run a compute-heavy task(e.g. The CPU fan should be at 100% speed starting at 80C. Hopefully it's a useful reference for you, fancontrol is quite helpful with errors if you screw up some values so tweak away! ~]# cat /etc/fancontrol The snippet below is my tweaked /etc/fancontrol file which took about 10 minutes of tweaking values to get everything just where I wanted. Native fan control via a USB controller on Linux. If you're happy with the outcome then enable the fancontrol service with: systemctl enable fancontrol -now If things aren't working quite right make changes to /etc/fancontrol and then repeat running fancontrol and so on.

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.
#Arch fancontrol driver
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.
