Is 3 Volts enough to power a cpu fan

well to blow air on me?

Here's something to play with,

How To Make A Cheap USB Powered Fan

Or just buy one,

no thanks, but I could cut a usb cable and hook it up to the CPU fan.

Air conditioner or ventilation fan? There is no way in this universe you will ever power an refrigeration type air conditioner with only 3-6v or even 12v and you aren't going to move enough air to ventilate a room using computer fans. You will need a really large, not to mention really expensive, PV array just to power a fan powerful enough to ventilate a room.

Actually instead, a portable fan.

I'd say 99% no. Many fans need more then 5v just to "kick" it into motion. At 3 volts you might get 100-200rpm and that wouldn't move any air. Anything running at 3v would probably be some tiny little fan. A CPU fan from 20 30 years ago won't work. A Guy

I have other monitors. Or if that one does not work, I could go to a computer repair store.

I've seen one of these before... we use to make one of these. until I forgot about them. thanks but we have lots of fans blowing in our house.

This one doesn't need much voltage

However, I feel like I want to make this one out of paper.

Turns out i don't need to buy a 6 volt solar panel. I figured out that this thing is high Efficiency and can easily be arranged for larger loads and higher voltage and current loads.
