Goal is to utilize the cheap fan found on Ebay and make it a 80mm USB fan without soldering.
Step 1: Material I Used
Here are the material I used
1. 80mm fan from Ebay - $1.99
2. 80mm Fan guard and rubber - $6.99
Step 2: Assembly
Put rubber and fan grill onto the 80mm fan
Step 3: 2 Pin Male Header and 2.1mm Female Power Jack Adapter
Screw tight for the 2 pin male header. You might need to extend the male header a bit to make it secure.
Step 4: Connect Fan and USB
Connect the 2 pin male hearder to fan's power (+) to red wire and (-) to black wire.
Connect to USB power and you should have a good USB fan to cool down like XBOX or Audio Amplifier.
