Step 1: Getting Started
So, first you will need:
A Justin Bieber Poster (nah, just kidding)
Okay, for real now.
A computer fan (DUHHHHH!)
Wire Stripper (optional)
The Fan's connector should look somewhat like the first picture,
and one of the USB cable's connectors should look like the 2nd and 3rd picture (just in case you don't know)
Step 2: Step 1
Now first,cut the connector off the fan. It should look like the picture.
Step 3: Stripping Wires
Then, strip the red and black wires. If you only have scissors, then just lightly cut the protective covering on the wire then pull it off.
Step 4: Same Thing
Step 5: Connecting the Used-to-be Connectors
Step 6: PLUG IT IN!!!!!!
Just plug it in to your PC or Mac or whatever and stay cool. Thanks, guys and PLEASE VOTE!
