First let me give a little back story / problem. I have a Dell XPS laptop that gets hot, Really hot. I first bought a belkin laptop stand for 20 bucks and the thing still works well its just that it elevates the laptop an inch and a half in the front and almost 3 inches in the back so for extended usage really kills my wrists.
I decided that I could figure out a way to build a fan in to my desk and power it by USB just like my laptop stand and never have to worry about the heat or the bad angle again.
I tried to be as thorough as possible in my instructable but its actually a pretty simple concept that anybody with a few tools could see exactly how I did it with just the pictures and recreate it rather easily.
I hope you enjoy the instructions and if you have any questions please feel free to email me or comment.
