Replacement GPU heatsink
I had to trim each of the 99 pins on the heatsink by 0.5cm, so it fitted under the DVD drive!
This larger heatsink replaces the fan+heatsink combination that the original Xbox shipped with. I used thermal tape to attach the heatsink to the GPU, which worked well and was clean and hassle free. The GPU operating temperature only increased by 1°C, which was better than I had hoped for.
At the same time I put some new thermal grease under the main CPU heatsink, which lowered its operating temperature.
