Yep! Thanks I was looking at 555s for a little but but then found a chip LTC6992. I can control the duty cycle with a 0-1 V input so im creating a voltage divider with a pot from 5v to obtain that, and that will be the user controllable fan speed.
Ill post a diagram and parts list once I confirm it all works.
