I am new to building circuits, so I am pretty lost...
I am building a laptop cooler, but I think the fan is too large to be powered by a USB output. I tried, and the fan moves an inch or so, but then it stops again. It is rated for 12V and 80mA. It is this one: https://noctua.at/en/nf-a20-flx
I then want to power it from the mains instead, and I have a converter from an old hair trimmer that outputs 6V and 650mA.
Can I use that? If so, how would I build the circuit? Should i go about this project in a totally different way?
Would it be possible to control the fan speed with a potentiometer?
Hope someone can help me.
