Welcome. I wanted to provide stripboard layouts I've made to help people new to electronics and even the more experienced get into different aspects of electronics.

I verify the layouts before I post them.

Linear PC Fan Speed Controller Stripboard Veroboard Layout


Extremely simple fan speed controller.

the input voltage depends on the fan you're using however the fan I used is a 12 volt fan so mine is powered by a 12 volt power supply.

I made this for a soldering iron fume extractor however it will work for your PC fans too and I plan on using it in mine.



here is a good video by fixitdaz on a very similar circuit
