Summary: The Zalman CNPS11X Extreme is equipped with one 120mm PWM fan that rotates at 1000-1950RPM and moves air through a pair of thin aluminum fin towers set at 80-degress to each other. Five 6mm diameter composite wick heatpipes conduct heat from the copper base plate to the twin 100mm fin stacks.
Excerpt: Just five months ago, we reviewed Zalman’s superb CNPS9900Max, which marked a return to the circle-of-fins look that has marked the big Z’s best-performing CPU coolers of the past half-decade or so.
Pros: Decent looks; included resistor cable.
Cons: Expensive; loud; outperformed by cheaper coolers.
