A few parts arrived other day. I got a 12v motor speed regulator. And a pc fan which has 4 wires yellow.black.blue and white.

which of these wires do i need to use as the motor reg only has 2 terminal ports

Cheers

red and black, pos / neg, the other wires are for rpm and for the PC to control the speed.

are you going to build in a raspberry pi to monitor and tweet the speed and estimation of the number of yeast cells, while live-streaming HD video of the yeast starter?

[Dave-Leeds]

Cheers irv. I tried that and it dint work.

just emailed place i got it from because i ordered 1 with only 3 wires and they are sending another foc

Cheers

iirc pc colour coding for wires is
black -ve
red +5v
yellow +12v
blue????

depending on your power supply if less than 12v use red n black, if 12v or more yellow n black

[vacant]

I think blue would be a tachometer reporting fan speed back to the PC.

The simple answer is there isn't a standardised colour set for PC fans. However the motherboard connector pinout is standardised. So just use that to see which wire corresponds to which pin. Simple



If that doesn't work look here
