I was thinking of creating this fan:

First I want to know if it harms the computer or causes any problem to it!

By the way, I’m creating this more for fun, and really think it’s cool!

    If your fan (or cooling pad for a notebook) draws too much power, you can get a USB hub which usually has an aux power input which can be connected. This is because USB will support many devices for data, but will only supply 500mA for DCV

    It works fine.

    seems intresting.But the output of the USB port will be around 5V.So have your fan around that voltage.

  • Usman Mubashir

    Be sure to use a fan that does not eats up much power, it’ll be fine,

    I didn’t have any problem in my 1 year exp.

    if you make it, it will blow… air.

  • Imesh Chandrasiri

    yes! it’s safe to make this fan! if the fan can get the needed power from the USB port, its safe!

  • Ron Lister

    If the USB tries to draw to much power it should shut off the power to the port until it recognises that the devise has been removed. So I think it will be alright to try.
