Noctua delivers their products well packed in nice Boxes, giving a great first impression.


  box inside

The box has a booklet cover with technical information and installation guide.

The NF-P14 comes packed nice and tidy with everything you will need to mount the fan.


The included extras 3:4-Pin Adaptor, 4 Fan Screws, Adaptors for 140mm mounting, 4 Vibration Compensators, Low-Noise Adaptor (L.N.A.), Ultra-Low-Noise Adaptor (U.L.N.A.).

The first thing that strikes me when I see the NF-P14 is the unusual layout of the fan.
The ordinary square fan look is replaced with a nice round frame.
The colors follow the Noctua standard, that people who care allot for esthetics do not like,
Me I want the cooling and acoustics so the colors is of no matter for me. 
The fan blades is a nine blade impeller design with Vortex-Control Notches, for more information on how all this works pleas visit … 

The NF-P14 is a 140mm fan with 120mm mounting, a very nice feature for people who want lower noise yet higher airflow. If your case has 140mm mounting holes you can just ad the 4 Fan Adaptors  to extend the fan mounting holes to 140mm mounting.
I like that Noctua included 4 Vibration Compensators it is always a plus to have.
One thing I never liked is the L.N.A and U.L.N.A, I rely wish Noctua would give the users a external fan control option even if it has to be mounted in the back of the case.
All in all the first impression follows the Noctua  standard of quality.


Installation, Test summery and and Fan noise.
Installing this fan is dead easy, at first I decided to try the NF-P14 as an exhaust fan, but sadly I found that there was to much noise going and I did not want to pull down the fan speed to much before I tested it fully.
NOW I have to say that this is not The NF-P14´s fault, most who have put some depth into making their pc quiet will know that the exhaust section on a case is a tricky zone.
The grill or stamped out exhaust holes on many cases is the actual cause of bad noise from the exhaust fans, many people simply cutout a big hole so the fan can work without any resistance allowing the air to float freely to achieve max airflow at minimum noise.
I felt that this case pushes allot of air
I placed the NF-P14 on the top 140mm slot of my Define XL case to se where I would end up.
I use the Fractal Design fan controller to be able to find that perfect spot for this fan.
I was stunned directly, I just had to lower the fan speed to about 1000 RPM and the NF-P14 became very VERY quiet in my Define XL case.
I decided to have a look at the temps of my PC.
And since I don’t wont to go all technical here I will just give you a small table of Temps.
Note that the room temps is on the higher side 28c for this test.
This test is meant to be as realistic as I can make it so I ran World of Warcraft for 1 hour before each temp reading was done.

Idle with NF-P14

Load before Load with NF-P14
MSI 560 TI 38 34 58 55
Northbridge 50 48 57 54
CPU 42 41 58 55

As you can tell from this table, the NF-P14 FLX does make a difference, all in all it helped my system drop at all temp reading points.

Building a PC for Studio work is tricky, a fast system requires cooling,
A studio pc has to be quiet, so the cooling you get has to be quiet!

Noctua has a true game winner in the NF-P14 FLX, the fan fits most cases on the market with its flexible 120mm / 140mm mounting system.
It is a Fan worth the price of around 21.9 euros, as you get a quality fan that works great.
As an intake fan the NF-P14 FLX rely shines, it is near silent up to about 1000 rpm when used as an intake fan, allowing allot of air to be bushed into the case.
No matter if you are a gamer or studio musician in need of a bit more airflow in your PC case the NF-P14 FLX is a Great buy!!
The only real downside I found is the Noctua L.N.A and U.L.N.A, I have to open the case to change the adapter to change the fan speed……
I would love a external fan controller to allow maximum performance / noise control.


  • Great performance
  • Quiet
  • Nice extras included
  • Quality
  • Fits both 120mm and 140mm mounting.


  • No external fan controller
  • Wish I had two!!!


Once again I would like to thank Noctua for letting me do this review.

And to you who read this.. THANK YOU!!
