Although the floppy disk is nearly extinct, many PSUs still have floppy power connectors. At a loss with what to do with them? Use them to cool off your tower by hacking a PCI Slot Case Fan!
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: For This Simple Hack, You Need:
A cheap "PCI Slot Case Cooler" (can be had <$10 on newegg)
An unwanted floppy drive
Shrink Tube or Electrical Tape
Step 2: Prepare the Connector
Use the pliers to carefully snap off the power connector on the floppy drive.
Break off the pieces of the board until you are left with only the plastic connector and 4 pins.
Use the soldering gun to assist in cleaning the old solder off of the pins.
Step 3: Prepare the Fan
Cut and strip the 4-pin molex from the fan
(Save that molex cable, it could be useful in future hacks!)
Step 4: The Final Touch
To avoid any unwanted contact, I recommend removing two of the pins.
Which to remove it up to you, yellow is 12v and red is 5v DC; both blacks are Ground.
I ran mine at 12v and it was too noisy for my taste, so I went with the 5v configuration as shown.
(Note: the pins can be moved from one slot to another in the connector, this isn't a permanent decision.)
Solder the wires to the pins, then shrink tube or tape them to avoid shorting.
Install into your case and enjoy!
