On one occasion I run a fan from a PC PSU at 17V - I had an ultra-slim PSU zip-tied to the light pendant flex, running a fan to chop up moths, wasps etc as they flew round the light bulb.Hello,
To start with, the fan is made for 5 Volts.
According to the datasheet it will work from 3 to 6 Volts.

At 5V wasps just bounced off the fan blades - and got pretty pissed!!! The 12V rails wouldn't power the fan unless the 5V rail was loaded, so I hung the fan from +5V to -12V.
At 17V the wasps still bounced off - but the concussion made them stupid enough to keep trying till they disintegrated.
