Have you ever wanted a small fan to blow on you. well all it takes is a few simple materials and you can stay cooler, without taking up your entire desk. 

STUFF YOU WILL NEED

2. Some scissors
3. Computer fan(s)
4. A power adapter
5. Electrical tape
6. Duct tape
7. Switch (Optional)

Here is a vid

Step 1: Choose Choose a Box and Cut It Out

Picture of Choose Choose a Box and Cut It Out

find a box that fits everything you want and need. Cut out breathing holes for the fans, and put a slit down the sides, make a "lip" shown below. this angles the air flow, so adjust to your comport. 

Step 2: Duct Tape Is Your Friend

secure the fans in but duct taping them to walls, make sure there is no tape in the area were the blades spin, it will make a annoying noise.

Step 3: The Wiring

This part is very simple to someone who knows wiring. if you dont that ok i have made a diagram for you 

IMPORTANT!

FOR A POWER ADAPTER YOU CHOOSE MAKE SURE IT IS THE AMPERAGE IS THE SAME AS THE FANS, THE MORE FANS YOU HAVE THE MORE TIMES YOU MUST SPLIT THE AMPS YOU HAVE

for example:
 
Below i have a picture of my adapter, my fans require 12v and .13 amps, so my adapter is 12v and 500mah which is .5 amps so each fan takes .13 amps, you must meet this number, or be below the adapters so it draws .26 amps out of .5. DO NOT GO OVER THE ADAPTERS AMPS!. make sure the volts is equal to the fans, this number does not need to be divided.

Step 4: Seal the Box

enjoy your simple but effective cardboard box fan!!!

I guess you could flip this 180degrees right? I mean put mesh over the fans so you dont bump into them and have the exhaust out of the back? Its a simple housing! good idea! :]
