Heatsink Upgrade
The Explanation

Heatsink Upgrade is a package of cooling mods
that maximizes the cooling potential of the Xbox 360.

The First Part of the Mod is about Heat Transfer from the Processors to Heatsink's
to better this I Wet Sand the Heatsink's to 1500 (mirror finish), reapply them with Arctic Silver 5
to fill any of the micro gaps left by the 1500 and bend out the X-Clamps to hold the Heatsink's on Tighter
(stock X-Clamps have a loose fit) This makes the Heat transfer from Processors to Heatsink's
Quicker and more Efficient so the fans can move it out of the console.

As an Addition to the Improved Heat Transfer Mods I also
place a piece of light cardboard over the GPU to help direct air flow
(overheating GPU is the main cause of 3 red lights) and add masking tape to the air channel.
