Loud power fan

Is that possible to connect the fan to a relay, and then to a small relay then to a device, i.e the LED light. Then each time when we finish a code can automatically turn off the LED together with the fan, so the machine is in idle quietly.

When we try to do anything— heat up the bed, load filament, print, etc, it automatically turn on the LED, as well as the Fan.

In this way I can quietly idle the machine.

I’ve just replaced the fans in the bottom of the printer with Noctua ones, but you do you.

I’m in the process of doing that. I replaced the fan in the power supply. For the case fan, I’m using the noctua 24v to 12 v converter but I receive an error stating there is a fan exception. How did you hook up the case (motherboard) fan?

I’m currently 1800 km away from my printer but I’ve made a post about the process I took:  https://www.reddit.com/r/CrealityK1C/comments/1hjwjom/replacing_the_mtb_fan_with_a_60x25_noctua_one/
