The MCW60-4870 waterblock is the world's first graphics cooling solution to combine heat pipe and liquid cooling to achieve extreme performance thermal characteristics in an economical package. This product is compatible with AMD's HD4870 reference design graphics cards only.
Based on the award winning MCW60 water-block which employs Swiftech's proven Diamond Pin Matrix technology, the MCW60-4870 base plate is CNC machined from billet C110 copper, then electroless nickel and chrome plated. It cools the GPU, memory, and extends to cool a heat pipe linking to the graphics card mosfets.
Since the MCW60-4870 uses the same housing and specifications as the MCW60 revision 2, thermal performance and flow rate are identical; the product also retains the same great installation mechanism with a sturdy back-plate, as shown below.
