Recently I bought an 18-inch desktop fan, ready for the summer. It has a rotary switch on it for three speed settings, but even the lowest setting is a lot like the back of a hovercraft.
The whole point of my buying a largish fan was that it could run more slowly and quietly, while still moving a decent volume of air.
With this in mind, I would prefer not to crack the control unit open in case I still want to return it for a refund.
Is it possible to in some way constrain the AC (110-230V, 50/60Hz) input so that it runs more slowly? Or would I need to work on the DC side?
