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.

1 out of 5 eggsDoes not fit

Pros: Looks large. Made of copper.

Cons: It cannot be installed. Here is why:
1. The top bracket and the bottom bracket lie about 1.5 inches off each other once fully in place. The supplied screws for them are...not 1.5 inches long.
2. The screws are directly under the fins, meaning it is impossible to use a screwdriver for them. You have to use an allen wrench for tiny screws. No thank you... not that it would do any good, considering the screws don't reach the bottom brackets.
3. Bottom brackets cannot be secured other than to the top bracket, so you kinda just have to hold it place awkwardly with your other hand or something while you try to apply thermal paste and place a 1 kg heat sink on top of your cpu.
Overall it is the worst piece of industrial design I have had the displeasure of witnessing. It looks like the designers took care to defeat the consumer at every step of the installation. If that was indeed their purpose, then it was a rousing success.

Other Thoughts: It does not fit the AM3+ socket, so maybe stop claiming that it does.

1 out of 5 eggs

Pros: -

Cons: The thing is absolutely massive. There is also an extremely loud and annoying clicking/buzzing coming from the fan. The screws were stripped by the allen wrench that came in the box and now I can't get it off the motherboard. Temperature of CPU is also still clocking in at the same temps that the stock CPU cooler had - instructions had told me to install the cooler with the fan going into the center of the tower and it's working in opposite with the external case fan.

Manufacturer Response:

Dear valued customer,

We sincerely apologize for the issue. Please contact our customer service e-mail support.usa@zalmanusa.com or via toll free number 1-888-925-6266 for further assistance.

Thank you.

Best regards,

3 out of 5 eggsNewer version flawed.

Pros: I've had one of these for years. They are quiet and effective.

Cons: These newer versions don't have the same clip mechanism and the old. The older ones had a simple clip mechansm for AM- based mainboards, easy to install and uninstall directly on the top of the mainboard- no backplate required. But the new version has an overly wide nut in the middle of the base that prevents the clip from fitting. So the only way for me to install this would be to completely take out my mainboard and install the full mounting bracket on the rear of the mainboard.

Other Thoughts: Why would they take away a perfectly good clip mechanism? I purchased this heatsink for that very reason, but now i will probably be returning it since i'm not willing to completely disassemble my computer.

5 out of 5 eggs

Pros: Keeps my overclocked Haswell I7 below 40C even after hours under load. Also, is surprisingly quiet for such a large sink. Who needs water cooling?

Cons: Instructions were worse than useless. Be careful when installing.

3 out of 5 eggsdisappointed ticking fan

Pros: good heat dissipation
high quality parts except for the fan (more on that)
sturdy

Cons: As the title points out, my biggest disappointed with this cooler is the fan. There is a distinct and very noticeable ticking sound coming from the fan. This is very annoying considering I specifically wanted a silent running computer so even at SLOW speeds you can hear the fan ticking. I would rather hear a low humming noise then a ticking sound.

Other Thoughts: Other then the ticking sound coming from the fan this would have been a five star product. Perhaps it is just the fan that I received, and perhaps, just hopefully the ticking sound will go away in time. But because of this ticking sound I would hesitate to purchase another Zalman product. This is unfortunate since I own three Zalman coolers and each have been good products but as a consumer I really do not want to deal with little issues like this.

5 out of 5 eggs3 years going strong

Pros: It has a blue led which goes with my blue led Antec 1200 case (check it out seriously) so it looks amazing. My i7 temperatures have been fine.

Cons: It gets a bit dirty in the fins and it's hard to get to. I try to use air, but it gets pretty dirty and needs abrasion. A toothbrush does the trick ok, but sill tight area.
