The slim ZALMAN CNPS8900 Quiet offers ultra-quiet cooling for low profile cases. An ultra quiet 110mm PWM fan, two Direct Touch heatpipes and aluminum fins combine to deliver efficient heat dissipation to keep your CPU and peripheral areas cool. Broad socket compatibility makes it suitable for almost all the mainstream motherboard platforms.

  • newegg Powerful cooling performance and quiet operation Two heatpipes and aluminum fins are designed for maximum cooling while switching noise free, down-blowing 110mm fan minimizes noise and cools not only the CPU but also provides powerful peripheral cooling. Moreover, the fan eliminates switching noise* for ultra quiet operation. (*switching noise is the high frequency harmonic noise that can result from voltage regulation).
  • newegg Direct Touch Heatpipe (DTH) Base DTH technology transfers the CPU’s heat directly to heatpipes, thereby minimizing heat resistance and maximizing cooling performance.
  • newegg Slim Profile The CPU cooler’s height is 60mm and designed to be installed in ATX cases as well as slim or LP (low profile) cases.
  • newegg Versatile Compatibility CNPS8900 Quiet accommodates a broad range of sockets including Intel LGA1155/1156/1366/775 and AMD FM1/AM3+/AM3/AM2+/AM2.
  • newegg High Performance Thermal Grease High performance super thermal grease ZM-STG2M maximizes heat transfer from the CPU to the base of CNPS8900 Quiet for intensified cooling performance.

5 out of 5 eggsSFF winner

Pros: got this cooler to stuff in the Asrock M8, its got a Z87/97 Mobo, so I picked up a K-series processor for my build. Even in this thermally challenged SFF case I've seen a 10°C drop under load (70+° down to 60° max).

Cons: The mounting hardware does not include anything to stop the retainer nuts on the bottom from spinning during install, not worth an egg off, just be prepared.

4 out of 5 eggslooks like I am limited to just 24 gigs of ram

Pros: terrific performance, really, hands down, fantastic, I can overclock the blitz out of my CPU (it is an a8-7600, but still) and it won't break 34 degrees C even with 2 massive Firepro V5800's in my tiny case going full blast

Cons: it does intrude into the RAM area so I can't use the rear most RAM slot, the backing plate would not remotely close to work to mount the cooler, I ended up using the plate that came with my motherboard and figured the rest of it out with the included hardware of both the motherboard and the cooler kit

the wire for the cooler seems bizarrely long for what it should be

4 out of 5 eggsFantastic!

Pros: Excellent cooling, low fan speed- runs quiet and very cool.

Cons: Low Profile design can crowd RAM if RAM has cooling fins (like mine). This is the only thing keeping me from giving 5 eggs.

Other Thoughts: I'd buy another one in a fact, I think I will!

5 out of 5 eggsQuietest cooler I've ever used

Pros: This fan is extremely quiet. Fits on motherboard very securely. The instructions are excellent and all the parts it came with are very high quality.

Cons: The fan is very wide (large diameter) and also if you have a mATX motherboard, there's a really good chance you'll not be able to use one of your DIMM slots. I had 2 4GB DIMMs and could only fit one. So I decided to get one 8GB DIMM and put in the one accessible slot. Also, this thing is not an easy install, but once installed, it's on for the long haul.

4 out of 5 eggs

Pros: Much quieter than my factory default model (AMD).

Cons: The space taken from additional RAM needs to be considered before purchasing. As well the fan itself is quite a challenge to install.

5 out of 5 eggsgreat value

Pros: -Quietest CPU cooler I've ever used. Even under load.
-Cools about 15 degrees better than stock at Idle, and up to 30 under load.
-very high quality piece. the pictures are a little deceptive.
- lots of overhead clearance. should fit in nearly any case.

Cons: Just make sure you have room for that Ram if you have a 2 chip M-atx or Itx board.

Other Thoughts: - People that are complaining about noise. Inspect your cooler very carefully when you recieve it for shipping damage. And inspect it again after installation for installer damage. I have no doubt that 100% of these complaints are user error.
- I was a little worried about ordering this because it looks a little flimsy in the pics. It looks like it will bend if you look at it wrong. NOT the case.. the fins are much thicker and sturdier than anything I've used before.
Also, if you are worried about the gaps in the contact base.. don't. It's machined pretty well, and thermal compound will easily fill the gaps.

4 out of 5 eggsGreat value

Pros: -Great performance and very quiet (not silent).
-My CPU run 5 or 10 C cooler with this than with the coolermaster 212 evo it replaced. I cannot explain this... but its awesome.

-Great value
-low profile
-great build quality and looks... lovely

Cons: Minimum fan speed is too high (~1000 RPM) and makes an unpleasant tone at this speed. This heatsink performs so shockingly well the fan should run much slower or just shut off for low loads.

May interfere with tall memory heatsinks on ITX motherboards. I had to cut the tips off of one of my memory sticks- no big deal.

2 out of 5 eggsMine is noisy.

Pros: Cools CPU
Slim design, fits in Cooler Master Elite 130 Mini-ITX Case

Cons: I had the same problem as Robert L below. When I first booted the computer I heard a extremely loud rattle. I thought a cable was in the way of the fan so I quickly shut down the CPU and took a look. Nothing there, booted again, same noise. I pushed down on the fan thinking maybe it was loose and now the rattling noise is gone but it is still very noisy. I hear the rattle from time to time, during boot up period. I bought this fan for two reasons. Slim design and because it is supposed to be "Ultra Quiet". And after reading someone else having the same issue I am disappointed with the manufacturers quality assurance.

Other Thoughts: Had already submitted rebate before building the system. After rebate it would cost almost as much to ship it back for RMA as it would to just buy a new one. May just spend a little more and try the Cooler Master Seidon 120
