Tall Slug
The original heatsink used to cool Valhalla on the Trinity motherboard. This heatsink was only used for a brief time.
Short Slug
This heatsink replaced the Tall Slug CGPU heatsink for cooling Valhalla, and was used on the Trinity and all versions of Corona. It was also used on Winchester with slightly shortened pegs on the bottom, as Winchester removed the IHS.
