The Llamma tracked down some Aavid heatsinks 30X30X10mm with pin style fins for optimum cooling. To add some enhanced cooling to the chipset just stick them on. Gain access to your motherboard and before reassembling this aftermarket heatsink can be added to the original Xbox Nvidia MPCX chip to allow it to cool more effectively. Or get two of these for the southbridge and video encoder chips in your 360. They fit perfectly and feature a self adhesive pad so they just sick right on!
