Intro: Improvement of the Laptop Stand, Diy
Improvement is to incorporate a fan reused, become fan via usb, to improve the cooling of my laptop, and lately I have experienced an increase in temperature on the keyboard.
This modification substantially improve this problem.
To connect a fan to the USB port, only need one cable unused, usb connector, a soldering iron and tin. It simply involves connecting the red and black wires of both devices and that's it.
If for some reason does not work ok, I recommend finding a usb connector cable double to connect in parallel, thus avoiding overloading a USB port, sharing consumption between the two, as do external hd drives.
