Features    [ Edit | History ]

Following in the footsteps of the successful NF-P12, the NF-P14 is a highly optimised, premium quality 140mm fan with Vortex-Control Notches for superb quietness and outstanding aerodynamic efficiency. Metal reinforcements, SCD2 technology and Noctua’s premium grade SSO-Bearing guarantee exceptional running smoothness and excellent long-term stability. Using the same hole-spacing as common 120mm fans and achieving a superior airflow/noise ratio, the NF-P14 is ideal for upgrading 120mm CPU or case fans.

  • 140mm Impeller with Vortex Control Notches
    Thanks to its psycho-acoustically optimised nine blade impeller with staggered Vortex-Control Notches, the NF-P14 combines superb quietness with exceptional airflow and static pressure.
  • 3 speed settings for full flexibility
    Providing 1200, 900 and 750 rpm speed settings via the supplied Low-Noise and Ultra-Low-Noise Adapters, the NF-P14 FLX (Flexibility) can be fine-tuned for superior airflow or maximum quietness.
  • Smooth Commutation Drive 2
    The latest version of Noctua’s advanced SCD drive system ensures superb running smoothness by eliminating torque variations and switching noises.
  • SSO-Bearing
    Noctua’s time-tested SSO-Bearing technology has become synonymous with supremely quiet operation and exceptional long-term stability
  • Round frame with 120mm mounting holes
    Using a round frame with the same hole-spacing as common 120mm fans and producing more airflow due to its larger diameter, the NF-P14 is a perfect upgrade for 120mm CPU or case fans. Thanks to the supplied adaptors, the NF-P14 also fits common 140mm mounting holes.
  • Metal Reinforcements: Both the impeller hub and the bearing shell of the NF-P14 are metal reinforced in order to achieve ultimate manufacturing precision, high durability and vibration-free running.

Noctua do i need to say more
there are non unless you buy a different companys fan
hands down Noctua makes the best fans period

Quality build.
Noctua colour scheme, price.
Comes with abundant accessories for various mounting options and speed/noise reduction cables. Ended up using the low noise adapter as I found it to be quiet but not as silent as I was hoping at full speed. Still moves a decent amount of air.

Experience: 3 Years
None so far.
Had mine for over 3 years on my current system. Zero problems, no vibrating at all. Probably best cooling fan I've bought in 12 years.

Experience: 1 Months
- Solid Fan
- Quiet
- Looks are far better than expected
- Cost, but worth it to those that buy them.
Solid fan, Added this to my Noctua NH-D14 CPU cooler after removing the other 120mm that came with it. With matching 140mm fans on the cooler, it looks fantastic. Only thing to look out for is the size of your RAM DIMMS with this setup and how high the fans need to be mounted .

Regarding the fan, it looks good, works good, and blows a ton of air through the cooler to keep temperatures down. Very Quiet.

Noctua FTW, now a huge fan... Hehe.

Experience: 3 Days

fits both 120 and 140 mounts
these fans are great for mounting wherever you need them. proveded you have room in your case, you can get creative with fan placement.

Experience: 9 Days
Looks Cool (for my Corsair C70)
Quiet !
None Yet !
It's a nice quiet fan that moves a LOT of air when paired with a nice fan controller. It looks awesome in my Corsair C70.

Quite, looks good.
I bought this to replace the 120 fan in the Noctua NH-D14 I Have for my I7 3770. I used the ultra low noise adapters on both and I can't hear it anymore, really not at all. I really recommend changeing the 120 out. I can't believe the flow out of my case with two 140's on ULNA. I run skryrim at full. 27inch monitor 1080, modded, and my mobo/cpu are about 37/39c after a few hours. Idle 27/29c in a 20c average room temp. I reviewed the noctua 80 mil fans and how I ported it right to the intake of my GPU and it keeps my GPU fan at about 50% in the same environment. Can't hear the build watching movies, surfing the net, and doing business. And gaming, I just hear it a bit. Thanks to the help from Noctua.

- Quality
- Quiet
- Cools Well
- Not Really designed to Fit in a 140mm Fan Spot
This model is more for a 120mm slot. It has metal extensions for 140mm slots, they will vibrate and make annoying sounds. I'm not sure why Noctua decided to do this.

If your looking for a 140mm fan for a 140mm slot, move along. Noctua has many other fans that will do it better.

RMA'd without a problem.

Great fans, very silent, comes with cable extension and silence adapter. Makes almost no noise and is great for radiators.

Experience: 20 Days
-moves a decent amount of air
-brown but cant see it anyways
Came with my D14 and i love this fan. just that the colour deters a lot of people from buying these

Comment: Fantastic performance, silent operation, a great set of accessories, awesome warranty cover and a not unreasonable price tag! All this makes the NF-P14 FLX a very highly recommended fan!

Comment: Today we have a look at a product from Noctua that may not excite many of you at first, but when you consider than most of your system noise comes from fans, you may rethink the benefits of a nice case fan. Noctua calls Austria home and has been in the cooling business since 2005. They've actu
