Swiftech Caldera 181g heat sink compound

Caldera - Aluminum - Black Initial release was CNC machined from billet aluminum. Revision 2 is now made of a custom aluminum extrusion allowing taller and thinner fins for better convective cooling. Fin orientation is now longitudinal. Cost is substantially lowered (new MSRP is $28.95)

The Caldera heatsink is designed to cool surface mount components (memory, voltage mosfets, I/O chip) on AMD's reference series HD4870X2 graphics cards.

The Caldera Heatsink is compatible with the MCW60 VGA water-block, as well as the upcoming Caldera 4870X2 water-block. In both cases, it will allow the highest possible stable overclocks of these high-end graphic cards while keeping them cool and silent.
