CoolerControl
Make the box stop shouting
Reads every temperature sensor and fan on the machine and lets you write curves for them — quiet under load you do not care about, loud only when something is genuinely hot. For a server in a cupboard the difference between stock fan behaviour and a sensible curve is the difference between hearing it and not.

coolercontrolInstalling it
Open the dashboard, find it in the App Store and press Install. Or from a terminal on the box:
sudo homebox install coolercontrolWhere to open it
| Service | Port | First login |
|---|---|---|
| CoolerControl | :11987 | No account — it opens on the device list. Empty means it found no controllable hardware. |
Open it at your box's address with that port — the dashboard links to it directly once it is running.
Good to know
- This needs REAL hardware. In a virtual machine there are no fan controllers to talk to, and it will start and show you nothing
- It runs privileged with the host's /sys and /dev: setting a fan speed means writing to a kernel hwmon device, which is not something a normal container may do
- A fan curve that is too aggressive is worse than the default. Leave headroom, and check temperatures under real load rather than at idle
