Tales from a Ventilation Lunatic

If the Fan you linked does indeed only draw 1.1 amps, then this product would likely be about the simplest way to control its speed. Built in voltmeter and finger twist potentiometer, just join 4 wires, input and output easy peazy.

It is rated at 2 amps.

Others shoud note if they hook a 12v fan to this, it would be easy to crank it well up above 15 volts. and a 1 amp fan at 12 v might pull 2 amps at 19 volts, and thus excees the rating of this buck/boost device, releasing its magic smoke.

I've made some small, not very powerful 12v computer fans levitate at around 28 volts through a 150 watt voltage booster, but I would not trust them to last very long at 2x+ their rated voltage.

Next summer I might be replacing those Noctua 120mm intake fans with the fans linked above. They are smaller than the FM181 net to them, and move 2x the air, almost, if their specs an be believed.
