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.

this design was great when s939 was around but now it looks dated. Zalman needs something like a vapor chamber cooler.

I'm curious how it will perform...
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)

Fluid-dynamic bearings fans usually have about 20-30K hours (~3-4 years) of operational time near CPUs before the continuous high temp from the fins "ages" them and they start to have an increased noise output compared to the factory default levels (they all start to hum louder after a while).
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.

Funny how most CPU Cooler manufacturers always add a picture of how shiny their surface area is. While shiny doesn't mean it's flat.

I believe Noctua has the most flat surface area of all CPU Cooler manufacturers around. And their surface area isn't even polished.

I'd like to see more vapor chamber base coolers, especially on quad core processors where CPU surface isn't equally hot...

wouldn't it be more efficient to put the 2 heatpipes on the intake? Isn't it going to have warmer air from the front heatpipe blowing on the back fins?

Looks like there isn´t any space left for another heatpipe unless you want to stack them.

this is the best way. if two is in the front then back one would be inefficient.

Why would you need to replace them if the lifespan is 3-5 years? Most performance users replace entire motherboards/cpus in that timeframe regularly.

Ugh, that is going to be a bitch to clean the dust out of it. I have the CNPS9700NT and since you cannot remove the fans, its very difficult to get between the fan blades and the copper fins to clear out the dust buildup.

Honestly I wish they had removable fans just to make cleaning all the more simple.

You remove the fan along with the stand that holds the fan.
I've used almost all kind of Zalman hsf before, and have no problem removing the fan.

this design was great when s939 was around but now it looks dated. Zalman needs something like a vapor chamber cooler.
LOL I think that was the last time I used one, actually now that I think about it I was using a Zalman on my s478 rig..(CNPS9500A LED)

It's nice to see Zalman making the cooler design which I have known them for again instead of pushing out OEM coolers and accessories, but will have to wait and see how it does in an actual test.
