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: Last I remember from Zalman, I was testing the CNPS10X coolers, of which there were four versions in total - two of which I got to look at personally. There was the Performa and the Extreme , both of which were typical tower based designs with a top cover and other tricks specific to the series. The cooler we are about to see takes on some of the attributes of these coolers, but harks back to the CNPS7 series of coolers for its outer appearance.
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. The CNPS9900Max resuscitated our faith in Zalman’s heatsinks, which had dwindled in the wake of skyscraper-style coolers and Zalman’s disappointing CNPS10X Extreme, a cooler that was larger and more expensive than its more effective competitors.
Pros: Decent looks; included resistor cable.
Cons: Expensive; loud; outperformed by cheaper coolers.
Summary: Unusual V-shaped heatsink, modest size, light weight and… outstanding cooling efficiency! Is it possible? If you have $89.99 to spare, then it is totally possible. The question is, will it be popular at this price point?
Summary: The Zalman CNPS11X Extreme was made to be a lighweight high-end CPU cooler. However, there is a contradiction between those two statements because an air cooler must be heavy to be powerful. So, the CNPS11X Extreme didn't show the same performance level as the huge top-shelf coolers with which we are comparing it.
In general, this cooler is a good one. It looks nice, mainly when turned on, with the blue LEDs in the fan.
Excerpt: Zalman really has it going on with the new 11X Extreme. The five composite heatpipes and the innovative design allow its fan to provide some excellent cooling with very reasonable acoustics. Really, the only complaint I have about the 11X is the mounting solutions. While the cooler is very secure with this mounting scheme, I miss the ease with which most previous Zalman coolers could be installed, even inside the case.
Conclusion: This is our first outing with Zalman and with it brings many different feelings and expectations. So how was our first experience with this well-established brand? The X11 Extreme is offers a unique visual appearance, its distinctive looks certainly separate it from other coolers on the market. Adopting a ‘V’ shape and having the cooling fan already attached is not only makes life easier but also offers excellent clearance for taller DRAM.
Summary: The Zalman CNPS11X has some of the best cooling that we have seen so far, cooling my overclocked 4.8GHz 2500k to an impressive 72 degrees Celsius while running Prime95. So as far as the cooling is concerned, the Zalman is a winner. The installation was easy enough and the supplied manual did give you all the detail that you needed to know.
Conclusion: Unser Fazit gegenüber dem neuen CNPS11X Extreme von Zalman fällt am Ende dieses Tests leider etwas getrübt aus. So geben sich die Koreaner zwar alle Mühe, Kühler zu entwickeln, welche sich zumindest etwas aus der Masse abheben, können bei der Kühlleistung mit der starken Konkurrenz aber nicht mehr mithalten. Auch die Montage geht nicht ganz so einfach von der Hand wie beispielsweise bei Prolimatech, Thermalright oder Noctua.
