I’ve been using this for a while now and it’s pretty good. For my watercooling it controls the fans and pump speed using liquidctl. Stuff plugged into the motherboard it controls directly.

However the connection between CoolerControl and liquidctl breaks all the damn time for some reason. With the latest update it’s broken again. I haven’t figured out exactly where the error is, because the error comes from liquidctl but I can’t reproduce it using just liquidctl. So it’s somewhere between CoolerControl (it’s daemon) and liquidctl. Once I figure it out I’ll post a bug report and it will be fixed soon I hope.

I wonder how much extra cpu load CoolerControl adds. Some manufacturer tools are known to be quite cpu intensive. I’ve seen the interval for CoolerControl be quite short, to react quickly to changes. But I think their clever way of splitting the UI from the actual control logic is very efficient. It probably means the cpu impact is minimal.

Excellent tool, would recommend!

For anyone on Bazzite there’s already a ujust script for setting it up:

ujust install-coolercontrol
systemctl reboot
#reboot
sudo systemctl enable --now coolercontrold

Woah, this is the software I’ve been looking for! This is absolutely fantastic
