So I’ve got a couple of Mini PC’s and a ODROID H4+ as a NAS, all just standing on my desk at the moment.
I’m going to build them into a 10" Rack and I’d like to have a good cooling solution.
My idea is to buy something like this https://www.alternate.nl/Noctua/NA-FH1-fancontroller/html/product/1917195 And wire it up with a ESP32 board and temperature probes, so that I can connect it all to a dashboard in Home Assistant.
Any advice on this project, or better alternatives would be appreciated.
If you want to do this as an ESP project anyway, you don’t need the extra controller.
Fans take a simple PWM signal, which your ESP (or even one of the smallest Arduinos) can create easily.
Good point, I found this: Tutorial - How to control a PWM fan with an ESP32 and Home Assistant ( https://www.youtube.com/watch?v=9-AZF6udg-Q ) I’m just going to do that but with more fans
