Heatsink
The Xbox 360 has used multiple different type of heatsinks for cooling the processors.
Xbox 360 (Original)
The Original Xbox 360 used 2 heatsinks: one for the CPU, and one for the GPU. There were also 2 different versions of each heatsink.
Heatpipe CPU
Used on the Xenon, Zephyr, and Elpis motherboards. It was also used on very early versions of the Falcon motherboard. Later revisions found on late 2006 and newer boards had less of a cutout near the rounded heat pipe on the side.
Aluminum CPU
Used on the Falcon, Jasper, and Tonasket motherboards.
Low Profile GPU
Used on early/mid Xenon motherboards, Zephyr_A motherboards, and returned on the Tonasket motherboard.
Extended GPU
Used on late Xenon, Zephyr_B/C, Elpis, Falcon, and Jasper motherboards.
Xbox 360 S and Xbox 360 E
The Xbox 360 S and Xbox 360 E use a single heatsink for the CGPU. There were 2 versions of the heatsink. Both versions have a fan mounted on them.

Tall Slug
Used on the Trinity motherboard. This heatsink was only used for a brief time.
Short Slug
Used on the Trinity, Corona, Waitsburg, and Stingray motherboards. It was also used on Winchester with slightly shortened pegs on the bottom, as Winchester removed the integrated heat spreader.
Prototypes
The following heatsinks were used on different Xbox 360 console variations.
Xbox 360 S Cooler Master Fan & Heatsink
Used on early Trinity prototypes, this heatsink is thicker than the final heatsink and does not feature a copper slug. This was used in correlation with a different fan shroud as well with F92 markings.
