Beryl AX cooling fan control in vanilla OpenWrt

When using vanilla OpenWrt, does the cooling fan works on a Beryl AX MT3000? What’s the GL recommendation to control the cooling fan while using vanilla OpenWrt? I’ve read about it and I saw that controlling it manually would reduce the fan’s life. I’d like to know is there’s an automatic and effective way to control it. And in case it doesn’t work I guess it can damage the router if it gets too hot.
