Conclusion: Zalman keeps up with current power hungry CPUs by changing its CPU cooler design once again. Its 3 heatpipes, a first for Zalman CPU coolers, successfully remove heat from even the most overclocked CPU. The all-copper design was passed down from previous models. The smooth polished base is a rare sight among coolers, so that is another plus, and shows the quality of the product. Zalman also lives up to its CNPS name.
Summary: The CNPS9500 AM2 heatsink is identical in materials and size to previous CNPS9500-series heatsinks, but since this cooler is being launched in conjunction with the nVidia nForce 500-series chipset and socket AM2 Athlon64, it has received a few special touches.
