Step 1: Step 1: Don't be a moron
For those of you willing to continue despite the risk to life and limb and inevitable financial loss; go to the next step.
Step 2: Procure laptop
Some of the methods could be done better, much better if you are not a cheapskate like me.
If you are a cheapskate, you could potentially use similar methods elsewhere and save a buck or two.
Step 3: Get other stuff
I used 3/16 ID vinyl tubing from the hardware store, it is strong yet flexible it has an OD of 5/16
I used 5/16 ID for this, if you can't see where I'm going with that...
I got one from ebay $20 shipped with power supply. If I were to do it again... I'd get a proper water cooling pump.
I'm using an add-on transmission cooler from O'reilly auto parts. It comes with mounting hardware and looks pretty nice. It should have the thermal capacity of 800 of the laptop's built in heat sinks.
Whatever. I'm using two thermaltake fans wired in series with a temperature controller. One fan is a smartcool the other is a thuderblade. Both together were $29 shipped from newegg. If I were doing this over, I'd skimp on fans and splurge on pump.
A gerbil water bottle from petsmart. It has a detachable clip on the back and 3/16 tube fits right in the hole where the metal drinking tube went.
I'm using a 13.5 v psu for the fans and a 12v psu for the pump (the one that came with it)
