There are a pair of Zalman heatsinks up for review at Bjorn3D, the 920g Zalman CNPS10X Extreme and the 700g Zalman CNPS10X Flex.  Both are based on five u-shaped heatpipes, the Flex being slightly smaller but with support for a dual fan configuration for better cooling and the Extreme comes with a handy PWM Mate so you can change its fans speed without difficulties.  Check out how well they keep the heat down on an AMD Athlon II X4 620 in their full review.

“The first thing that comes to mind for most people when they hear that name is ‘CPU heatsinks’. Since 1999, Zalman has been providing great products designed to keep PC components cool, especially CPUs. The Zalman CNPS10X Extreme and CNPS10X Flex continue the Zalman tradition of providing great cooling components for CPUs. While the Flex allows you the flexibility to choose your fan setup, the Extreme provides a controllable PWM fan for immediate installation.

It seems the days of bland CPU coolers are gone. They have all been replaced with engineering masterpieces designed to pull as much heat away from the CPU as possible. From installation to benchmarking, we put the Zalman CNPS10X Flex and Extreme to the test.”
