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 eggsMISSING PARTS

Pros: I'll update later if they fix the problem - otherwise I'm returning for a refund. Gross.

Cons: My brackets, which are essential to the installation process are not bent. As in, I half almost half an inch of space in between the bolts and the screws. No contact, no threading and INSTALLATION IS IMPOSSIBLE.

Other Thoughts: It took me over an hour and a half to pull everything apart, put it all together and in the FINAL step, the bolts are unable to be threaded. Amateur hour.

Refund, replace or send me the correct brackets overnight mail. Youtube is FILLED with comments about people in similar situations. I should have researched more before spending the money.

Manufacturer Response:

5 out of 5 eggsSecond Time Much Easier AMD Install

Pros: This thing really works. CPU Temp dropped 15 C after install. I decided to do this after I installed one on my son's MOBO ASUS (AMD Sabertooth AM3). He has an AMD 6-Core 1075T. I have the AMD 8-core with the same Sabertooth AMD MOBO. I have 32 GB of memory . He has 16. I had been getting quite a few BSODs, apparently these were due to overheating as I was able to observe CPU temp at over 60 degrees centigrade in one instance before it BSOD'ed.

Cons: The directios are not very clear. Also the screws look like they won't reach the base posts. This is an optical illusion. The thing comes together just fine.. The thing is admittedly large, and depending what is in your case could be a tight fit. In my case, my 3 fan Video card is m,ore of a pain. You need to completely disassemble your PC and turrn your MOBO over to assemble this thing.

Other Thoughts: Keep the plastic on until the last steps as you can get cut on the sharp copper edges of this unit.

5 out of 5 eggs5 yrs old & still performing well

Pros: Purchase this last Zalman 9900 cpu cooler in late 2009 and just had to update my 7/1/2009 review in the interest of info sharing with other pc enthusiasts. Until this month I had a total of 2 of these Zalmans but sold my oldest Zalman 9900 cpu cooler having upgraded to a refurbished Corsair H100i water cooling upgrade. I originally paid over $40 for the Zalman some 4+ years ago and sold it to a work associate who just wanted to mildly overclock his 4770k. Offered to let it go for $35 along the installation and he agreed. This was a "win-win" for all he was guaranteed a 4.2GHz o/c on his 4770k which I would guarantee and I would recoup $35 thereby lowering my out of pocket cost on the Corsair H100i to just $55. For those who are still on the fence about going with a air cooler you should seriously consider the Zalman products simply because the manufacturer supports all the sockets presently out there including the new Haswell-E's. Quality of Zalman coolers are top notch and the longevity of the ball bearing fans speak for themselves...4+ years and still going strong. All that's needed is the bi-annual cleaning with a good industrial air compressor. Just be sure and blow out both the video card fan, power supply fans and any dust bunnies you have accumulating with the mid or full tower case. Again, I avoid using toothbrush or any brush since it potentially introduces static which might occur. BTW, the bottled heat sink compound provided with the original Zalman 9900 cooler is among the best pastes out there. A few drops of rubbing alcohol (isopropol or grain alcohol ...whatever you having laying around) will remedy a infrequently used bottle of this paste). Should Intel come out with another never ending socket platform down the road a quick call to Zalman will get you a bracket kit to accommodate newer sockets down the road .... never ever had issues with Zalman support...top notch!

Cons: Zalman has both a aluminum and older copper finned cooler. I prefer Copper over aluminum .... why fix what isn't broken?. The Zalman 9900 has outgrown it's usefulness for aggressive overclocks but is still better than the stock Intel cooler

Other Thoughts: This cpu cooler plays nicely with Haswells for mild overclocks so if you have one of these legacy coolers think twice before you toss it out. It does help when dis-believers see a 5 year old air cooler happily chugging away overclocking a 1st gen Intel 4770k to the tune of 4.3GHz with no throttling whatsoever...YMMV!

5 out of 5 eggsFor the money very good

Pros: This is the third one of these I have bought. the reason being they do an excellent job for a non liquid cool solution. The truth be told, liquid cooling does work well but how many computers really need it. Probably not many. In any case, this keeps the my CPU in very cool with no problems.

Cons: The biggest con is you must be careful when handling this as the fins can be sharp. Take your time and everything will go together.

2 out of 5 eggsDoes not fit FM2 MB

Pros: It's a big solid copper heat sink. Let's be honest, it's probably overkill for most.

Cons: This came with screws that are easily a quarter inch too short.
The brackets would have to be bent considerably to make them reach. I had to go out and find 3 mm bolts and use those. Bolts bottomed out, so not really sure if this is secured down well enough. What a ridiculous mistake.

Other Thoughts: Do the research or be prepared to modify this yourself.

5 out of 5 eggsGREAT CPU Cooler

Pros: Perfect, keeps the temp 20C under from stock. It is pretty big, so make sure your case can fit it.

Cons: Installing can be tricky, but take your time.

5 out of 5 eggsPerfection..

Pros: [-] One of the best free air HSF's on the market for appropriate CPU
[-] Keeps things real cool.... but read other thoughts

Cons: [-] Doesn't come with an ISO 1 cleanroom

Other Thoughts: Ok, so the "con" (not truly a con of course) concerning the ISO 1 cleanroom. This HSF is great. My spouse and I keep things very clean. However, every three months this thing shows us (between its fins) just what the Dyson and Central A/C system doesn't filter out of the air. I purchased an attachment for the vacuum typically meant for cleaning tight spots in a car, etc. to clean this bad boy (in two computers of mine). Any build/case that will allow it (due to room/compatibility), I use this for the HSF!

1 out of 5 eggsLemon?

Pros: Good air flow and is quiet. Large but still fits case.

Cons: There are quite a few reviews that claims that the brackets do not reach the bolts and this is the same case with me as well.
If you look at installation videos, the bolts from the back of the motherboard are much longer and the bracket itself would stay on the motherboard. My rear bracket kept falling off and the bolts were barely able to touch the screws from the top bracket. It's might be impossible to fit on LGA 1150.
They might be sending out different bolt sizes unintentionally. On the other hand their specification page on newegg list it as compatible with LGA 1150 but it is not listed on the overview page.

5 out of 5 eggsAwesome fan

Pros: This fan is awesome! It's very quiet most of the time, looks good, and keeps my i7-950 very cool even at a 30% overclock - and the 950's were not known for having low temps... I've had this fan for a couple of years now and fully intend to use it when I upgrade to an i7-4790k later this month.

Cons: This can be a little difficult to clean because of the sheer number of blades and how close they are to eachother. Getting in between each blade to clean all of them takes time. They can also be a bit sharp, I've gotten plenty of little nicks on my fingers when installing, cleaning, or generally poking around in my case.

Other Thoughts: Be aware that this fan is rather large and will stick out a decent ways into the case. Make sure your case is wide enough to fit the fan after install - I actually had to file away a part of my old case to get it to fit! When the fan ramps up to 100% it can be get a little loud, but it cools so well that this rarely happens anyway. The rest of the time it's so quiet I can't even hear it over ambient noise in my apartment, much less my other case fans.
