Instructions
Turn off your Xbox 360 and then unplug it from the power outlet. Remove the power cord from the back of the Xbox.
Look for the Intercooler on the back of the Xbox. There are four tabs on the Intercooler. There is one on each side at the top of the Intercooler, and one on each side towards the bottom of the Intercooler.
Squeeze each side of the Intercooler just above the tabs with your fingers and pull it out. You do not need any tools in to do this.
