Hi everyone.
Despite having googled for it, I’m still not sure whether or not DietPi supports [the official Raspberry Pi 4 CPU fan](https://www.raspberrypi.com/products/raspberry-pi-4-case-fan/) or not? As far as I understand it, Raspberry OS/Raspbian ship with CPU fan controller software built straight into the CLI GUI. However, it seems like that feature has been left out in dietpi-config?
Unless there is official support for controlling the fan, I’d very much appreciate any help that’ll let me explore my options. For the record, [this GitHub thread](https://github.com/MichaIng/DietPi/issues/4003) discusses how to let DietPi control the fan. In one of the posts, this command is suggested:
```nohighlight
echo 'dtoverlay=gpio-fan,gpiopin=14,temp=60000' >> /boot/config.txt
```
Does it make sense to “manually” add an entry to /boot/config.txt using the echo command or a text editor, or are there any fancier ways of doing it that is preferred?

yes DietPi did not offer any GUI to control fans in general. Because if we implement a feature like that, we would need to do it for more platforms. And not just RPi. There are more solutions out there how to run a fan on a SBC 🕶
Especially for RPI devices it’s quite easy as you just need to run the echo command once, to initially add support.
```nohighlight
echo 'dtoverlay=gpio-fan,gpiopin=14,temp=60000' >> /boot/config.txt
```
After a reboot, this should be working ootb. At least I was testing it on all available RPi modesl. Later on you could simply use a text editor to manage temp value on your need.
Personally I don’t like the official fan as mine is quite noisy one.
