Noctua NF-P14 FLX Case Fan Review - Testing and Final Thoughts



Until we get our decibel-meter, we will do our tests by isolating a fan, and doing a very close aural inspection, which just means we will just listen closely!  We used a long fan extension to get the fan far from the case itself, and pace it through its entire range of RPMs using our Scythe Kaze Master Pro fan controller.

Well, as we expected after getting to test Noctua's NF-S12B FLX Fans, this thing is truly ridiculous!  The SSO bearings are as close to perfect as I can describe, these things spin perfectly, no wobble or vibration whatsoever, and when the fan is powered off, the fan continues to spin for a solid 25 seconds!  Now, the thing anyone looking to buy this fan is concerned about... how loud is it?  Well, it is about as close to silent as you could possibly get with conventional fan technology!  The only word I can describe what it sounds like is a simple "wisp" of air, but that doesn't mean it isn't moving air, it is pushing TONS of air even with this nearly non-existent level of noise.  The large blades really take a deep "cut" of air and pushes a ton of air, and generates an impressive amount of pressure as well!

I've spoken with many people who have commented that these fans "couldn't possibly be that much better."  Well, they really are a step above the rest, and despite their hefty price, those who are truly passionate about silent computing will surely find these worth every single penny!  And as I commented on the NF-S12B FLX fans, they really may not be that expensive when it is all said and done.  If you have a run-of-the-mill fan that cost 10-15 dollars, you could easily go through 2-3 of them during the lifetime of one of these supreme Noctua fans.  The SSO bearing is going to give these ridiculous lifetimes, and may very well be a smart and worthy investment!



  • QUIET!  As close to silent as I can imagine you could achieve
  • Great airflow and pressure
  • Plenty of cabling and accessories, such as rubber mounts
  • Minimalistic bezel and fan housing
  • SSO bearing is SMOOTH, almost no vibration whatsoever, and should produce very long fan lifetimes


  • The one and only con.... the Price, at nearly 30 dollars after shipping at many retailers, these cost a pretty penny, but due to longer lifetimes, may be a good value in the end.

Noctua has blown us away once again (pun intended), and the Noctua NF-P14 FLX has received the Tech Kings Crown for an excellent and recommended product!
