Simple voltage limiter
I recently added a 180MM computer muffin fan to my intake window. The fan, a silverstone FM181 which employs a variable speed 10k ohm potentiometer, has an operating voltage from 5v to 13.2v. ht...

This is what all my earlier uproars are all about with regard to MOSFETS, opto couplers, free-wheeling diodes, yadda achooo...
In the works is a massive Orient order for PC boards, heat sinks, MOSFETS, precision resistors, Opto Couplers, terminal strips, etc. Next comes the small project boxes. Someone is asleep at the switch with regard to RELAYS.
But the adjustable BUCK regulators sold on eBay are easy to use (you set the voltage out in the open BEFORE you mount the critter).
Mount the buck regulator SOMEWHERE where it will fit then adjust the length of the 12 volt wires or output wires to fit.
Remember, these critters need two volts of breathing room. 10.00 volts needs a minimum of 12 volts input. Anything closer (above 10 volts) can be adjusted ,7 volt a whack with series rectifiers. I found 10 amp 1000 volt silicon rectifiers on eBay cheap. They work fine paralleled.
