Just ran into this article about making a heat spreader for the HOT Athlon processors a la Intel.
It's pretty damn cool so I had to share it with y'all.

3°C to 5°C improvement under full load using the modified CPU with heatspreader. These results are still acceptable using my aging Kanie Hedgehog 238 with a C/W of 0.41 equipped with a low speed 80mm cooling fan. It's safe to say that this project was a success. Not only does it look very cool, but it also lowers temperatures by a few degrees. Also, the core is protected from being damaged by the spreader.
This project was relatively simple and inexpensive. I recommend this project to anyone advantageous enough to try it. Of course, neither Icrontic or myself can be held accountable if you break your processor doing it.
