I replaced a noisy 80mm fan with this one in the back of my case and the difference is nothing short of phenomenal. Now, most of the noise I hear is from the CPU and power supply fans, and if I'm not next to the machine it's often hard to tell that it's running...even in an empty house. Great product!

To the previous reviewer that couldn't tell the "low noise" and "ultra low noise" adapters apart, there is a small slip of paper that came with the fan. The adapter with the red shrink-wrapped part (resistor) is the low noise. The one with the black shrink wrap is the ultra-low noise. However, the fan is so quiet that I opted for the higher air flow and didn't bother with either of these.

I wanted to install a push/pull setup for my H50 radiator, so I wanted two identical fans. I installed these on the back of the case. I had the stock set up as intake, as suggested by Corsair, so I wanted to see if setting the fan up as exhaust really would downgrade performance. It did, the push/pull set up as exhaust cooled much worse than one fan as intake. So I reversed the fans, and set them up as intake, and it works great. I noticed that from stock to 3.8 Ghz I had virtually no temperature change on my i7 920 processor. So I run it at 3.8, core temperature idles under 40 C.

I have a CM Stacker 830 case (all fans 120 mm) , with these two fans set up on the rear exhaust opening as intake, and then I have two hard drive cages with fans in the front acting as intake. Then I have one fan on top set up as exhaust, and three more fans on the side set up as exhaust. The radiator causes some problems with the side door that holds the fans, so there is no fan over the CPU space.

I have the Noctuas connected to the MB CPU fan controller, using a fan cable splitter to ensure that both fans are running at the same RPM. The other six fans in the case are hooked up to a 6 fan controller in the front, and I keep those turned to the lowest level all of the time. I still can't hear the Noctuas running at full speed over the rest of my 120 mm fans running at slowest speed.

This is a fantastic product. My system use to sound like an airplane ready for takeoff until I got these. They are very quiet, efficient & use very little power.

The Noctua NF-P12 case fan is really and truly remarkable. I'm currently using this 120mm fan in a push pull exhaust configuration along with the Corsair H50 liquid cooling system. Let me tell you I was speechless. I can hardly tell that my system is running. This fan is giving me high air flow by using psychoacoustic optimizations. The fan blades have vortex notches in them which enable the fan to run smooth as silk and deliver the air mass that is needed and required. I love my Noctua fans. Big ups for Amazon.

I have 3 in my case. They are still as quiet as the day I bought them.

I replaced a Silverstone fan with this unit. It's VERY quiet, and it increased air flow enough to drop the motherboard temp by 20 degrees! Only two issues: Which cable is which (low noise vs very low noise)? [I left off the adapter cables so that the unit can reach its max rpm when needed.

Other is the color....oh well, you can't have everything!

This is the third fan I bought from Noctua.

I continue to be impressed by the workmanship of this Austrian fan producer. The fan is silent, yet produces a massive air flow of up to 92.3m3/h at 1300rpm and 19.8dB(A), which is barely audible from 1 yard away. You can also use two different extension cables to reduce the RPMs, airflow, and make the fan inaudible. Also, the fans come with great flexible rubber attachments for reducing vibrations, as well as classical screws. I usually use the rubbers, as they have the added benefit of quick installation. This particular fan ended up in a push/pull configuration for water cooling an I7 860 with a Corsair H50, and it works great.

Throughout the last 20 years, I must have purchased around 20 different computer fans. I was never really satisfied until I found Noctua. If you're tired of funny noises coming from under your desk and want maximum cooling for overclocking your computer or a long life for your expensive hardware, get one of these: Simply terrific, strong and silent fans.

This Noctua brand fan is quiet and moves a lot of air for the RPM.

I previously bought a lot of Nexus and Yate Loon branded fans and still have many of those in use with good results.

The reason I started trying these Noctua brand fans is that they come with 2 little electrical wire adapters to slow the fan speed.

You can run the fan at stock (normal) speed, or when one of these little adapters is fitted, it changes the electrical resistance that is facing the incoming electrical power, and hence the fan speed will run slower. How much slower depends on which adapter is fitted.

For a given quantity of air moved (CFM), these have lower noise (db) and fan speed (RPM) specs.

So far, I can't see any degradation in performance versus Nexus or Yate Loon, and the noise profile seems at least as good if not better.

Being able to switch the speed of the fans with the adapters allows me to stock and use fewer part numbers.

Here are some specs:



Stock (no adapter fitted):

19db / 54 CFM / 1300 RPM



With Low Noise Adapter (LNA) Fitted:

17db / 46 CFM / 1100 RPM



With Ultra Low Noise Adapter (ULNA) Fitted:

13db / 37 CFM / 900 RPM

After reading all the reviews and recommendations, I decided to try these case fans. I was pleasantly surprised at just how quiet they really are. I have them installed in a custom built HTPC; replacing the case fans on a Tsunami tower. One for intake at the front, one for exhaust on the side panel (after modifying the panel) and one to replace the fan on a Corsair H50 cpu cooling system that was much too loud for my liking.
I did not use any of the included mounts or wiring to lower noise or speed. The fans' speeds are controlled by the mother board. From 10 feet away, in a quiet room, you can barely notice that the computer is running; and, then, only if you are aware of it.
As far as the cooling properties, the internals of the computer remain consistant at 46 degrees C under load. This is a room with an ambient temperature of 78 degrees F.
I am about to modify my personal computer with a similar setup. I highly recommend these cooling fans for performance and noise reduction.
I have been building my own computers for over ten years and will be using these from now on.

Ditto what the other posters wrote. The Noctua NF-P12 case fan is dead quiet and works great.

I never understood why everyone had trouble with the silicone mounts, but I do now. Lousy design--I snapped two before I gave up and used the regular screws (included). Doesn't matter, though. The fan is so quiet that I can't hear it even though the computer is right beside me.

No instructions included. Had to go to the web to identify the other cables. Tossed them, too, and connected directly to the motherboard for maximum RPM.
