[SOLVED] Is it safe to run pc case fans as quiet as possible?

[m.kudinovv]

Hey! I am controlling pc case fans with arduino and mosfet transistors via PWM. And I wonder do case fans have a low speed limint, under that their lifetime will reduce? Or it’s safe to make speeds as low as possible?

P.S. temperatures will be fine even on low speeds.

In my experience....the main reason you don't want to run an electric motor slower than it was designed for is that there is a potential for them to overheat.

As long as you aren't overheating them I think you will be fine.
