I built a Volumio media player using a RPi 4 in a custom small metal enclosure. Since it's a RPi4, I was having a heat dissipation problems. Since it's a media player, I didn't want a fan constantly running, so I looked for a simple fan controller where I could switch it on/off based on the RPI reported temperature. This tiny PCB from Jeremy works perfectly!! It's reliable and smaller enough to include inline in the power cable.
One issue; I wish there was a script all ready to use to drive this. I wrote one, but am having troubles with running it detached in the background when the system boots. I am sure there's a straightforward way to do this, just wish it was already documented here.
Jeremy is a great person to deal with!!

Well thank you so much Steven!
As for the script, check this out on GitHub: https://github.com/JeremySCook/RaspberryPi-Fan-Control - I should probably add that to the product listing. You can also use sudo raspi-config and choose your fan settings under Performance Options, though I'm not sure if that will work under Volumio.
I bougt this for my Raspberry Pi 4 to controll it's 5V Fan, but it didn't work. I Plunder it in the gpio ports on the Pi and Set Pi to controll the Fan over the gpio Pins, but the Fan didn't turn on. It's pausble that i plugt it in the wrong way, then i ned a good Manuel to use it right.

Or this video should show you the details of how to hook it up: https://www.youtube.com/watch?v=AdjU_AVcZTA
If you're looking for a Jeremy S Cook sticker, you won't find any that are better than this! Perfect for sticking on things that need stickers on them. Or things that don't. I'm not going to tell you what you should do with your stickers!
