Reply to comment by Sea-Manner-9238 in Best way to run PC fans from outlet? by Tamariniak

So the voltage on a power supply is a constant supplied voltage and the current rating of the PSU is just its maximum current? Meaning I just have to match the voltage and get a higher (maximum supplied) current than the sum of the fans?

Also, would you happen to know how I could regulate the speed? Is 12V the slowest or the fastest? Is it safe to run the fans at a lower voltage than what their rating is?

EDIT: one more thing, at a lower voltage, would the current flowing through the fans be lower than the rating (via Ohm's law) or does the current somehow stay the same regardless of the voltage?

Yes

That should be fine, though a PWM controller might be better.

Theoretically yes? But I’m not sure if there is something funky about the way motors work.

Only one way to know for sure…
