Engineered in the USA Product Updates 6-26-09 Now shipping with Rev2 heatsink The Caldera cooling system is upgraded to Revision2 heatsink; MSRP is reduced to $139.95 Introduction: The Caldera 4870X2 is a hybrid cooling system for AMD HD4870X2 reference graphics cards. It is composed of two separate elements: a water-block that cools both GPU's, and a passive heatsink to cool surface mount components (memory, voltage mosfets, I/O chip). Compared to monolithic solutions, the primary advantage of uncoupling the cooling elements is to optimize the cooling capacity and the thermal joints for components that need it the most: the graphics processing units. The Caldera 4870X2 water-block utilizes Swiftech's proven Diamond Pin Matrix technology to cool the GPU's and guarantees superior thermal dissipation to promote the highest possible overclocks.
