Will this be efficient?
It will provide them with full speed power as long as they're plugged in,The efficiency part is up to you.

If you do use a USB cable , you only need two of the inside wires in the usb cable ,because one of them is often a data wire (you can cut that one & wrap it. ) you can look online for a guide how to hook a USB up to a fan it's pretty easy

Although... it could be fun to see a 12v fan hooked up 230v

View attachment 99881

Ok, maybe not "fun"
Or connect 20 of them in series so that the voltage across each of them drops to 12V and put a diode at one end for DC voltage.

Gloriously unsafe and impractical lash-up with half wave rectification and no smoothing, but it should "work"...
