"The CNPS8700 LED, which was introduced at CeBIT 2007 in Hanover, Germany, is an all copper heatpipe and heatsink CPU cooler with a lower profile and larger, 110 mm fan as compared to the CNPS7000. The CNPS7500-Cu offers improved performance over the CNPS7700. It is also made of 100% copper and has an 110 mm silent fan just like the CNPS8700. Both coolers sport the Flower Heatsink Design, which is comprised of a plethora of copper fins atop a copper base, with a clear fan with LED lights set in the center of the fins. The only major difference between the two is that the CNPS8700 LED also has heatpipes incorporated into the design. Which one cools better? Are they as quiet as Zalman claims? These thought-provoking questions are just what this review will attempt to answer."
