Control the Raspberry Fan

Updated on 2021-03-21

Raspberries can be really loud

(20th September 2019)

When you have a raspberry near you with the little fan connected to the 5v you will notice that it can be really annoying. I was already loosing my mind with it so I had to fix it.

I was searching the web, and found that controlling the fan speed based on the temp. was not that hard. Besides I have never had any experience with electronics so this sound really fun 😄

A mini side project was born!

All I had to do was to follow this article https://www.instructables.com/id/PWM-Regulated-Fan-Based-on-CPU-Temperature-for-Ras/
It contained all the details about what I needed to do. So U bought some material I was missing and started playing around.

Ok, so I managed to make it work 😄 Now I had to make it nicer and smaller to fit the case.

Which I missed…
But… This was my first circuit ever! And it still served for quite a while. I got it working for months.

Some day i saw I could make it even smaller and put it totally inside the case.

I’m happy with it, although it’s not pretty. It works and it was a nice experience. I learned a lot 😄
