Long popular for the design and engineering of their products, Zalman continues to deliver on their tradition by producing quality products backed with excellent service. The CNPS9900LED goes a step further by looking good as it cools your AMD or Intel processor.

The efficient dual copper heatsink design combines a 3-pipe system that effortlessly whisks heat away with the help of the 120mm blue LED fan’s blades and 2 ball bearings. Noise level can be lessened automatically by using the integrated PWM functionality which lets the BIOS monitor fan performance and thermal need and adjust the fan's speed accordingly.

The CNPS9900LED is compatible with all single- and multi-core CPUs for Intel's Socket 775/1156/1366 and AMD’s Socket AM3/AM2+/AM2/754/939/940. All the clips and backplates are included so there's nothing else to buy to get the unit attached to your motherboard in minutes.

  • newegg Pure Copper Heatsink Base and Fins A pure copper base and circular heatsink formed by radially aligned ultra-thin (0.2mm) copper fins maximize heat dissipation surface area for excellent cooling performance.
  • newegg High-efficient Heatpipe Design The innovative heatpipe design delivers a heat transfer capacity equivalent to 6 heatpipes with just 3.
  • newegg 120mm Cooling Fan with PWM Function The 120mm cooling fan with PWM function automatically adjusts speeds according to the CPU temperature for the optimum balance between cooling performance and noise level.
  • newegg Universal Socket Compatibility As an all-in-one solution for PC systems, the ZALMAN CNPS9900A LED features broad compatibility with all AMD socket AM2, 754, 939, 940 and Intel 775, 1156 and 1366 platforms.

4 out of 5 eggsExcellent CPU Cooler!

Pros: Unique design, blue LED fan, all copper heat pipes and fins, noticed a reduction in CPU temperatures over stock cooler by an average of 17 Degrees Celsius (at normal loads) even when overclocking the CPU.

Cons: Can be difficult to install. If possible, install this CPU cooler Before installing the motherboard into your case. Since my motherboard and other hardware was already installed, it was rather difficult to install, and like many others, I had a great deal of cuts on my hand with blood, nothing serious, but can be painful. Trying to screw in the bolts to attach to your motherboard is difficult, as you have a hex key -type tool and have to use an odd angle to screw in the bolts, thus causing cuts on your hands.

Other Thoughts: This is a great CPU cooler and does it's job well at cooling the CPU. I recommend this cooler to anyone who does not prefer liquid cooling, just try to install the CPU cooler BEFORE installing your Motherboard and other hardware if possible. I also can confirm that this CPU cooler DOES work with Socket LGA 1150. Minus 1 egg for difficult installation, would be nice if it was a push-pin install rather than the odd angle you have to screw in the bolts to your motherboard, otherwise this would be 5 eggs.

4 out of 5 eggsamazing cooler

Pros: have had it for a year and only just recently it made a skitter sound and the fan stopped spinning and i had to restart my pc to get it going again. (only happened once)

keeps my AMD FX-6300 at 9c idle 44c max when at 100%.

Cons: Must be installed with mother board out of the case.

very heavy moving your system could undo or break a good thermal compound bond.

Had to remove the board to install, ackward hex screws directly under the main body of the cooler.

fan is not replaceable or this thing could be a lifetime cooler.

5 out of 5 eggsMonster Cooler - Beware!!

Pros: Keeps the I7-4790K at near ambient temperature even during a stress test. It's big so beware! At over 1.6 lbs make sure your MB can handle the weight, you can find the specs for it on their website. Make sure you have a case with the depth to fit it in.
It was installed in a Fractal case which is wide so no problems. It's round and does not interfere with ram install. It does a great job of cooling for the money.
Installation was easy by the instructions IF you go slowly and do it by the book. I installed it on an 1150 socket MB with no problems.

Cons: Almost didn't buy it because I wasn't sure it would work on the 1150 socket. There isn't anything on the box that declares it will. It is listed in the instructions though.
Fan direction information in booklet is messed up.

Other Thoughts: Probably will only buy many more of these.

3 out of 5 eggsThey changed a great thing

Pros: I guess used to be zalman was the easis=est and best cooler that has changed ... and its not the quality .. it seems effective but now its a pain in the buttox

Cons: They changed the mounting method and Its a PAIN .. I too stripped out the Allen head bolts the older way was so much better and easy as pie this way is very inconvenient << had to use this word as I couldn't post this otherwise... I have never purchased anything but Zalman in the past several 92mm and a 120 but this one is the first for the new mount method.. I will try other brands now.. there has got to be a better way

4 out of 5 eggsFollow up after 2 years.

Pros: I've had this running on an FX 4170 OC'd to 4.5 gigs. Been idling at 14° for the entire time. When stressing the CPU, I get up to 67°, sometimes a little higher when the room is hot. After 2 years the thing still runs strong. I would buy another if I was building another system.

Cons: Mounting was difficult and takes a lot of patience. It is har to clean.

I'm not fond of the blue LED lights.

Other Thoughts: My wifes computer has the XIGMATEK Gaia and it is noisy compared to this one (they both get loud under load). Both these cool OC'd AMD CPUs very well. The Gaia was MUCH easier to install.

3 out of 5 eggsIts ok

Pros: Benchmarks were really good for this on Toms Hardware. It really is a great cooler.

Cons: The cooler arrived with the fan brushing against the rear fins. I had to try to bend the fan forward a bit to keep clearance.

Other Thoughts: I purchased this in 4/2014 and wasn't going to write a review, but I just had another questionable build quality Zalman arrive today. It is a different model (CNPS8900) so now I am 0 for 2 with Zalman.

5 out of 5 eggsas everyone mentioned, it's a tough one to install

Pros: I did what everyone recommended and I got it ontop of my 1150 Intel successfully.
Make sure, as mentioned by others, install when board is not in the case. Makes it easier to do.
Read very very carefully the instructions as well.
This is my sixth generation Zalman, and by far the most complicated to put on.
Zalman, what's up with that?

Cons: Very difficult to install

5 out of 5 eggsGood cooler, bad install method

Pros: Great cooler, period! I bought a Zalman two bearing cooler in 2006 and it worked flawlessly the whole time I owned it. The only reason I bought this cooler was because I rebuilt my old desktop two months ago and wanted a new CPU cooler to go with the new build. The first Zalman worked great and I'm sure this one will also.

Cons: Installation method on this cooler was direct but a real pain. Luckily for me I still had the steel clip that was used to install the old Zalman cooler so I used that instead of the brackets and hex head screws sent with this cooler. The hex head screws were not deep enough to keep from stripping.

Other Thoughts: If you have another installation method other than the bracket and hex head screws ... buy this cooler.

1 out of 5 eggsinstalation sucks!

Pros: nice fan but...

Cons: The installation hardware is made of butter!! they use Allen screws to mount it to the bracket, due to the size of the fan it isn't easy to get to the screws and the metal is SO soft the hex head strips out quickly. this is made worse by the fact I had a DOA board so I had to do this twice. I don't think the the custom screws will take a third install.

Other Thoughts: use a better grade metal, this nice fan isn't worth anything if you can mount it properly.
