Noctua (NF-A14 PWM) - 140x140x25mm Square Frame Fan, 4-pin PWM, 1500/1200rpm max

100% Positive Reviews
Rated #286 in Fans & Heatsinks


Pros: Comes with sleeved LNA, PWM splitter, extension cable ; can be mounted on 280 radiators

Cons: It's very brown (love it or hate it I'd prefer black for the top of my case) , REALLY expensive MSRP , Availability is poor

A $24 at most retailers I'd go for a $13-16 Thermalright TY-147 which looks better and is about as quiet (but comes with no accessories, vibration mounts on the corners, silicone screws, or Noctua warranty). However, Noctua fans do not possess any PWM clicking.

Considering that a sleeved PWM splitter goes for about $4 and a pack of 12 rubber fan screws is about $3+shipping I took the chance since I found them on sale for a very competitive price.

They're dead silent at 900RPM.

When put on the top mount of a Corsair Carbide 300R (even if using the silicone vibration mount fan screws) will cause a odd noise at above ~1100RPM. This not occur when put on the front panel where there is a simply filter and a plastic hexagonal reinforced frame. I can't imagine anyone putting these in pull on a radiator, that would probably annoy me. Reviewers at sites around the internet have stated the NF-F12 / NF-A14 FLX has a problem in pull as well , making a sucking noise.

One of the problems with using it as a case fan is that if you are putting it on front intake there is no way for you not to use the extension cable. You also have to plug in the LNA (low noise adapter) unless you want them to run at 1500RPM ,which means you have two cables in series going into your fan header (three in series for me since I had 2 front intakes on a PWM splitter).
The important thing to know is that you must put the LNA after the PWM splitter or the RPM reading on the motherboard will go nuts.

To put the silicone fan screws in takes a pair of needle-nose pliers and patience tongue.gif. You need to put it into the hole from what you're mounting to (case) and then pull it through using your pliers very tightly.

I don't possess equipment to measure airflow in my house otherwise I'd measure the airflow for you guys tongue.gif

I bought a pack of 3 from Amazon for $43 otherwise I wouldn't bother. Newegg still doesn't seem to carry them as of July 10 2013.

Noctua (NF-A14 PWM) - 140x140x25mm Square Frame Fan, 4-pin PWM, 1500/1200rpm max

The NF-A14 is a premium quality quiet 140mm fan with a square frame that complies with Noctua's AAO (Advanced Acoustic Optimisation) standard. Its square shape and 140mm mounting holes (124.5mm spacing) make it ideal for use on watercooling radiators or as an upgrade for 140mm case fans. Featuring sophisticated aerodynamic design measures such as Flow Acceleration Channels, the NF-A14 further improves the renowned quiet cooling performance of the award-winning NF-P14. The PWM version sports Noctua's custom designed NE-FD1 IC for fully automatic speed control via 4-pin fan headers and comes with a Low-Noise-Adaptor to reduce the maximum speed during PWM control from 1500rpm to 1200rpm. Its performance-oriented 1500rpm top speed and comprehensive speed control options make the NF-A14 PWM an elite choice for users who strive to strike a perfect balance between excellent cooling capacity and superb quietness of operation, be it on watercooling radiators, on heatsinks or in case ventilation.
