Well, I'm a little puzzled by this question. There are fans inside of
desktop computers and fans that sit on desks. All desk fans that i am aware
of are powered by electricity (battery, AC, or even solar panels), as are
the fans inside a computer.

Fans are inside computers because the electricity moving through the many
circuits builds up heat. Too much heat and those circuits may be damaged.

Fans use the most simple type of motor, and a good description of that
motor is at

Hope this helps,
