Picture of Build A Laptop Cooler!

Laptops' CPU and GPU overheat a lot sometimes, and If you don't want to watercool, you can add fans! In this I'll be showing you how to make your own laptop cooler! You'll need the following:
Computer Fans
Some kind of building material (Try for plexiglass or Lexan)
Soldering Iron
SPST Switch(s)
DC Power Supply
All of these you can obtain through eBay or the dump. I got my soldering iron, solder,switches, and wire from Radioshack, the fans and DC power supply from eBay. The links are below:
DC Supply - (It has 1000MA of power AKA: 1A)
120mm Fan (Not the best airflow, but it was cheap, if you want a better fan go buy one.)
Now, the number of fans you want to use is up to you, just make sure you have enough AMPS on your supply.

Step 1: Step 1-Preparing

Now the first thing you'll want to do is take your fans, chop off that molex plug, leaving only the red and black wire. Strip the red and black wire, and do the same for the power supply. Now we're going to tin the tips of each wire, basically put some solder on each one.

Step 2: Step 2-Setting Up The Connections

Solder the connections. Below are some examples of circuits that can be used. Remember, you can use whatever 12v fan you want and however many you want, JUST MAKE SURE YOU HAVE ENOUGH AMPS ON YOUR SUPPLY TO POWER THEM! First picture is a one switch set-up, second picture is a two switch set-up.

As easy as tinning sounds, a bunch of people fail with it, when they dont hold the iron on log enough, or too long, and it doesnt take right. Or they don't pre apply solder to the iron.
