Goal is to utilize the cheap fan found on Ebay and make it a 80mm USB fan without soldering.

Step 1: Material I Used

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.
