5 STAR !!
I rarely hear the fan spin up faster and never see temps over 45 C even while running gaming applications.
CON: It is large and may require a little caution when installing depending on how your power wiring in your PC is setup. I had to tie one power wire to the case to keep it from touching the heatsink. Also it's own power wire for the fan needs a little care when installing. It can be pulled to tight and interfere with the fan.
Install was simple but does require you remove the motherboard as there is a back plate you must install to support the weight. It does not use the horrible push pin locking system that the factory setup does.
Zalman has a great reputation and I thought this fan might do the trick.
My system is whisper quiet, even when I tax the CPU heavily and the video card, -even at the same time. I never thought my computer could be so quiet.
Some things to keep in mind.
1) Take your time, read the instructions, and be careful of the fins, they're sharp.
2) Make sure you face the fan in the right direction, it's not in the logical direction you might think. In my case the fan is on the far side of the back of the case and you might think otherwise when you first look at it.
3) Instructions need to followed if your installation is going to work. It's a bit of a puzzle, especially if you only use the printed instructions.
4) I strongly recommend you USE THE ZALMAN WEB SITE for help with the installation. Go to their web site, find this cooler in their product list, and once you're at this product's web site you'll find an installation tab with a very, very good animated installation guide.
5) Be sure you select your correct CPU for instructions, the Intel and AMD instructions are VERY different (due to the way they mount to a motherboard).
Considering the cost, and the 30 minutes to install, I think this fan is worth the time and effort and cost.
An excellent product!
It's not as big as the CNPS9700 (good), but it does its job well. The copper base came machined flat, very smooth and shinny. The fan is black in color and has no LED's.
As far as fan noise...quiet, quiet, quiet...even at load. Did I say quiet?
And speaking of the fan, one of the selling points for me was the fact that the cooler comes with a 4-pin Pulse Width Modulation (PWM) fan which allows the motherboard to automatically control the fan's speed. The fan draws power from a 4-pin fan header installed on many of the newer motherboards. This helps to keeps fan noise to a minimum as it will only ramp up when needed. As such, there is no fan mate is included with this CPU cooler. However, 4 pin PWM fans are backwards compatible with 3 pin fan headers...but, you would lose the ability to control the fan speed by plugging a 4 pin PWM into a 3 pin fan header. This is something to consider, especially if your MB does not have a PWM header. In that case, you'll need a cooler with a fan mate/controller to control the fan's speed; otherwise the fan will run at full throttle.
So does it work??? Well, it dropped my CPU temps at least 13C, if not more. No kidding. I have a Core 2 Quad Q6600 (2.4GHz) B3 stepping which I had running at 2.66GHz with idle temps of around 59C in an Antec P182 case with stock fans. With 9500 AT installed, I'm now at 2.9gigs with idle temps of 46C, 75C load with prime 95 running. Some will say this is hot, others will say it's about right. Such is the CPU I have!Read more ›
However, assembling the cooler is a bit trickier than the instructions report. The instructions correctly state that one has to remove the protective shroud before using the cooler. What the instructions do *not* say is that the protective shroud must be removed *before* one can install the base bracket on the cooler to mount it in the case. I wasted quite a bit of time trying to install base bracket on the fan before I realized that simply cutting off the protective plastic shroud made assembly simple.
I recommend the Zalman CNPS9900A LED CPU cooler highly and without reservation. It is a highly effective cooler and it is beautiful, with a bright blue LED, while doing its job.

With ambient temp of 30+°C, my i5 2500k idles at 44-48°C and under load at under 52-56°C
I applied my own thermal paste, not the one given in the box though.
