Zalman CNPS9900DF CPU Cooler Launched
Zalman's newest high-end CPU air cooler, the CNPS9900DF, has been on our radar since May. It was launched in select markets earlier this week. The Computer Noise Prevention System (CNPS) model 9900 heatsink has been leading Zalman's product line for years now, with several variations being launched from time to time. The newest one, the CNPS9900DF, in which "DF" stands for dual-fan, builds on the concept by using two fans in push-pull configuration. The "push" fan is nested in the first copper fin stack, while the "pull" fan is located between the two fin stacks. The design is otherwise similar to every other 9900 series cooler.
The design of the CNPS9900DF consists of a nickel-plated copper base, from which four nickel-plated copper heat pipes pass, making a capital-omega (Ω) shape, along which nickel-plated copper fins are arranged, which appear to project radially. The surface area for heat dissipation is 6,800 cm². Measuring 140 (L) x 100 (W) x 154 (H) mm, the CNPS9900DF weighs in at 850 g. The 120 mm "push" fan spins at 1000 RPM, while the 140 mm "pull" fan spins at speeds between 900 to 1400 RPM. Both fans use fluid-dynamic bearings, and the total noise output of the cooler is said to stay within 27 dBA, according to Zalman. The Zalman CNPS9900DF is priced at an estimated US $89.90 a pop.

This one does excellent job...
Pity that I didn't know about that one when I bought the Archon(which was 2/3 of its price at the moment)
The "problem" with this design arrives when you need to replace those fans, because they are more expensive and harder to find/replace than the framed ones.
I believe Noctua has the most flat surface area of all CPU Cooler manufacturers around. And their surface area isn't even polished.
why they use 1 heat pipes when the other they place 2 heat pipes
and i dont like their fans, what if someday you need to replace them or you wanna pair it with another fans.
Honestly I wish they had removable fans just to make cleaning all the more simple.
i have washed graphic cards before, this is nothing :p
I've used almost all kind of Zalman hsf before, and have no problem removing the fan.
