Zalman Releases CNPS20X Twin Tower Cooler - 300 W TDP
Zalman has now achieved global availability of their CNPS20X twin tower cooler, an air-cooling solution designed to dissipate up to 300 W of heat from your CPU of choice. The Zalman CNPS20X features loads of heat transfer technologies, including RDTH (Reverse Direct Touch Heatpipe), an evolution of the now ubiquitous DTH (Direct Touch Heatpipe) technology applied to its six heatpipes, alongside IHD (Interactive Heatpipe transfer Design) for increased thermal performance (Zalman claims this last technology brings improvements in heat dissipation in the order of 20x).
Not only the heatpipe design has been touched upon, though; the company also employed what it calls a 4D corrugated fin design, which means the fins themselves have contours (imagine a honeycomb shape and you're close) that improve heat dissipation and airflow. There's a stack of fins built out of copper, which are located close to the center of the airflow to improve heat dissipation further.
Zalman's Dual Blade impeller technology is also employed here, which the company claims concentrates airflow instead of dispersing it along the outer channels. The company says they have employed a biomimetic design principle to their fans, inspired by spider legs, and achieving reduced vibration and noise on their fan operation (besides the usual gains in employing fluid dynamic bearings). The CNPS20X also features RGB lighting compatible with Razer Chroma. The CNPS20X is available at a pricing around €90.

D15 is definitely showing its age during this new era of massive amount of cores. Looking forward to @crazyeyesreaper review on this
D15 had a good run, but has had some good competition lately.
It probably doesn't matter, but since I stare at engineering blueprints all day long, I get paid to be curious (and possibly concerned) when I see things like this :D
The fans themselves are rather interesting; the same versions Zalman sells do not have the black square frame, thus turning them into "frameless" fans. It'll be interesting to see if anyone will ever review them independent of the heatsink; maybe either as intake or radiator fans, and if the black frame helps any with air channeling (as opposed to frameless).
Noctua is still the king in my opinion.
The greater cooling of the Zalman is only achieved through a greater surface area, at the cost of weight, size and clearance.

20X: 140 x 170 x 165 mm
D15: 165 x 150 x 161 mmI dunno, the 17X makes the D15 look expensive.
Kinda makes sense because you want the heat out faster now that more is built up under the die, suits the boosty nature of CPUs better I guess. Well I guess its progress that for once isn't just marketing or cosmetics. Nice.
PSA: I wouldn't go all crazy on the KitGuru review alone. Definitely needs second opinion for scoring so well.
Those were the days, where Zalman could compete against Thermalright SLK-947 (but then SP94/SP97 came and wrecked them all) and had the best GPU cooler on the market, which could handle Radeon 9700 Pro passively.
Arctic is the one not getting enough love at the moment imo for its price point anyway.
As to the brand Zalman, based on my experience with the "customer service", I would recommend against getting anything from this brand. I've wrote in to the "customer service" at least 3 times, but never ever got any response from them. That was at least 3 years back since my 3 queries went, and till now, still nothing from them. I wonder if there is anyone doing customer service there in the first place.This is true. I think the Arctic 34 eSports DUO is worth considering as a good tower heatsink alternative.
