Summary: Without the included resistor cable, the CNPS12X is quiet. It’s very quiet with the resistor cable, and so if you’re not overclocking, the CNPS12X is an appealing and beautiful cooler. But given the flimsiness and frustration of the install process, we can’t recommend it for overclocked LGA2011 cooling.
Summary: Final Thoughts
Zalman once again has another over-the-top CPU cooler and it does perform very well. With an average idle temperature of 32 degrees and average load temperature of 49.5 degrees you won’t have to worry about your CPU getting hot at all. The average between idle and load temperatures was 18 degrees, which is very good, but with 3 fans I did expect better results.
Pros: Great cooling performance, Very quiet, Easy installation, Compatible with the latest CPU’s
Cons: Large size makes it hard to install on most systems with enthusiast memory, Not much of a difference in quiet and performance mode
Summary: With the CNPS 12X Zalman managed to once again surprise me. The baseline performance is excellent, and in fact amongst the best heatpipe coolers we have tested. The true benefit however needs to be found in the total cooling capacity, we can always se that really well once we increase voltages and start to overclock. Even at 4200 MHz with 1.5V on the CPU (which is way too much Voltage) under full stress this cooler manages to keep the CPU cores under 70 Degrees C.
Excerpt: To sum up, the CNPS 12X is a very worthy addition to the Zalman stable. The six composite heatpipes and triple fan/dual radiator design yields excellent cooling performance at a very modest noise penalty. The cooler's enormity may limit its use in some cases and it's a bit fussy to install, but the 12X will deliver some astounding cooling performance in exchange for some diligence and patience on the part of the user.
Two Pounds of Pure Efficiency: Zalman CNPS12X Super Cooler Review
5 December 2011
Summary: I have to admit that at first glance the new Zalman cooler doesn’t seem to be very promising, resembling mostly some sort of a modding part. However, it turned out to be a real state of the art super-cooler!
Summary: Based on the characteristics found on the Zalman CNPS12X CPU cooler (large size, three fans, six direct-touch gapless heatpipes, etc.), we thought it would reach outstanding cooling performance. However, it seems like Zalman favored silence over performance. Even with three fans, it is quieter than most high-end coolers, yet it presented only good (not excellent) cooling performance.
Summary: The Zalman CNPS12X heatsink marks the first forray into exposed heatpipe coolers for its Korean manufacturer. For what I can only assume are trademark reasons, Zalman term it whole direct touch heatpipe.
