Just a heads-up... the square redux fans have been updated!

They now support the chromax anti-vibration pads (NA-SAVP1), so you can customize these a little, if you prefer the gray colors of the redux line. I've been using Noctua fans pretty much exclusively for 10 years now. The redux line are actually some of the original Noctua designs, in a much more neutral gray color scheme that doesn't clash with everything else inside your PC. (The redux colors also aren't as likely to get the PCMR nerds riled up like the regular beige/brown color scheme does.) This means they're using some of the older Noctua fan designs, and up until recently, they were also utilizing the original-style square frames without the integrated bumpers. They also forgo almost all of the usual Noctua accessories, which means you only get screws included with the fan (these are Noctua's "budget" fans, after all). But the cables are still sleeved, same as the regular and industrial lines. There's really not much else to say... I mostly posted the review to let people know that they redesigned the square versions to take advantage of the chromax bumpers. If you're new to Noctua fans, they have a reputation for being silent, but that's not entirely correct. You can definitely hear them (unless they're running at very low RPMs), but the sound they make is usually a little more pleasing to the ear-- or at least somewhat less annoying, compared to most of the competition. These should work fine for both case and radiator fans; just make sure you take advantage of the PWM feature to help keep the noise down when the extra airflow isn't needed.

Superb fans!

The 'grey' (Redux) model of Noctua fans are the previous generation top tier fans, so you will not be getting the absolute 'latest and greatest' that Noctua has to offer. That being said, they're the best fan I've ever had the pleasure of using. The previous fans I have used over the past 20 years (various generic, Arctic, Corsair & CoolerMaster) all pushed less air (CFM) but made a considerable amount more noise. Are these fans more expensive than the others? By a few dollars on average, yes. Are they worth it? Absolutely! Due to the quiet nature, reasonable cost, controlled temps and sleek grey appearance, I've started the process of replacing every fan in all my computers with the Redux series of fans - the tan and brown are a 'no go' for me as that color scheme is hideous to my eyes, regardless of their performance.

through the door of my case--is vastly superior to that of the Venturi HF-14 placed at the ...

I replaced the stock fans on my Corsair H110i GT and it is now much quieter and cools more efficiently. My i5-6600k @ 4.4 ghz idles around 25C, hits high 20s when CPU usage its around 11-15%, and during gaming loads tends to be between 45 and 55. Using CPU-Z to stress it, my package temp stays under 60. This is a few degrees improvement over the stock Corsair SP140s. More importantly, my case's airflow has improved. I have the radiator as a front intake, with the fans in pull position (on a Define R5). My gpu is an MSI blower style gtx 980, which really benefits from fresh air. I purchased a high-flow Fractal Design fan for the bottom intake, but I wish I had gotten another noctua high static pressure fan because of the air filter and perforated metal base on my case. The airflow coming from these NF-P14s--through a radiator, through an air filter, through the door of my case--is vastly superior to that of the Venturi HF-14 placed at the bottom intake position.

The best fans I've found! Quiet + PWM

Love these fans! Very quiet. They are 4-pin Pulse Width Modulation (PWM) fans which means that you can control the speed of the fans with the appropriate software. I have three of these 140mm fans and one 120mm fan in my case currently. Two of the 140mm fans are driving a Noctua NH-D14 CPU cooler (awesome cooler by the way!) which took some zip tie ingenuity since they don't fit the clips that come with the NH-D14. The other 140mm fan and the 120mm fan are acting as case fans. Under normal usage, the two case fans don't even run and the two CPU fans run at about 20%. Under heavy load the case fans ramp up to about 40% and the CPU fans get to about 50-60%. Again... VERY quiet! *UPDATE* Fans still work perfectly! I added 2 XFX R9 390 graphics cards to my rig and the fans run at about 50% when gaming. My computer acts as a pretty respectable space heater, but the fan noise is still very acceptable. A low, quiet hum. Also, the commenter was correct that it is Pulse Width Modulation, not Pulse Wave Modulation... Thanks for the correction. :)

Awesome!

I absolutely love these fans. I purchased 5 of them to put throughout the case and they function beautifully with SpeedFan. The only thing that I would have against them is that Noctua sends their fans out stock with some god-awful brown anti-vibration pads as a ploy to get you to spend more money on new ones (kind of shady of them). But outside of that they've not only made my case quieter, but significantly cooler than the fans I had before.

Moves a lot of air!

I bought a couple of these to replace my case fans and bolt to a 280 AIO radiator. The 280 AIO came with ML140's and during some testing, prior to installation, was shocked at the performance difference of these NF-P14s! The NF-P14s ran at a higher RPM! Ran quieter at a matched RPM(max RPM was louder, but the ML140 only went to 1050rpm)! And pushed WAY more air! Setting both fans up next to each other; I set the NF-P14s to a barely audible RPM (850) and could feel air movement several feet away! Turning up the ML140's to max (1050 rpm) only produced air movement within a few inches of the fan. I'll still need to test the performance while bolted to the radiator, but for now, I'm VERY impressed and would HIGHLY recommend this product! One quick gripe...; The material that protects the cable is nasty! Kind of a sticky rubber tube, that kinks in tight bends and easily collects dust.

High flow, low noise.

I put 2 of these as exhaust fans for my Corsair H110 to replace the noisy stock ones. They are mounted horizontally and blowing up and out of the my case. No more rattles or weird grinding noises and they dropped my temps 5c to boot! For some reason I was always hesitant to believe the Noctua fan hype, but these have made me a true believer.

Great replacement fans for Kraken X60

I bought two of these fans to replace the ones that came with my Kraken X60, and I'm very happy with the results! I did some head-to-head comparisons of the stock fans against the NF-P14s reduxs; I tested both ends of the spectrum: quiet and max. For the quiet test, I tried to get the most cooling power for the quietest setting. The stock fans are audible even at their lowest setting (25%), but they don't provide much cooling. The P14s was whisper quiet up to 1000rpm (~60%), and provided better cooling than the stock at 25%. Definitely a win for the P14s in this test. For the max test, I simply ran both fans at full blast (100%) and checked their cooling power. The stock fans were a couple of degrees cooler, but they sounded like a hair dryer. The P14s sounded like a gentle desk fan by comparison. The stock fans win for max cooling power, but the P14s wins for sound and efficiency. Bottom line, these fans make a great replacement if you are looking to make the X60 much more quiet. If you only care about maximum cooling, then stick with stock or maybe go with the NF-A14 ippc-3000.

Great fan, brittle blades

Great fan! Moves a TON of air out of my hot machine! Watch out for the brittle..and I mean BRITTLE fan blades! There was a single wire that curled up into the blades and broke 3 of them of in an instant. I've had wires get in the way of fan blades before but never had one break. So be careful about that and you will LOVE these fans! After I got my first one, I replaced ALL the case fans with these fans.

Excellent value, good airflow and quite

I installed this as a front intake fan on a new build in a Fractal Define R5 almost 18 months ago in order to create a positive air pressure in the case, the computer is on nearly 24/7 usually with the fans running on a low speed because i'd rather risk shortening a fan's lifespan than keep it "silent" and have all the fans off. At low speeds fan cannot be heard, at higher speeds it moves more air than the stock fractal define fans, but is not as loud as them. This is an awesome fan for the money, and as a bonus I've seen the effects of positive airflow first hand when my brother's build in an R4 has to be cleaned every other week and mine is usually fine for a few months
