Flow Acceleration Channels, you say? Tell me more.

Maybe you read the product description and aren't sure what, "turbulence to the influx in order to facilitate the transition from laminar flow to turbulent flow, which reduces tonal intake noise, improves flow attachment and increases suction capacity" means. That's okay. All you need to know is that there's a reason these fans are so highly rated. All of my case fans, in all of my computers, are Noctua's. I replaced my Corsair AF140s with these. I replaced my NZXT FN V2 fans with these. I replaced a lot of different brands' fans with these. Neither of the aforementioned brands' fans are bad, either; they're just not *as* good. The cooling performance is top notch, but what really makes them shine is the noise ( or lack thereof ). These ( and Noctua fans in general ) are really the only choice for a quiet PC build that doesn't compromise on cooling capabilities. Yes, they're more expensive, but they're more expensive for a reason. And really, we're talking about, what, ~$5 difference in price? Skip the Starbucks for a day and you're covered. Seriously. It's worth it. 10 / 10 will continue to buy for every PC build going forward

The NF-A14 PWM is the best all-around 140mm fan in the world.

The NF-A14 PWM is the best all-around 140mm fan in the world, even better than its more expensive brother, the iPPC variant. There are a few points that are worth knowing: 1: Quiet. Like all tan and brown Noctua products, the NF-A14 PWM is borderline silent in almost all uses. The beauty of this is that it requires no knowledge, or specialized software/hardware, to get it to run appropriately. Simply plug it into a PWM-enabled fan header and let the computer run it. It'll be silent or near silent in almost all conditions. 2: Powerful. This fan produces excellent pressure and airflow. Unlike the 120mm fan Noctua equivalents, the 140mm line is designed, in general, for all-around performance, so it works great on heat sinks/rads, intakes and exhausts. 3: Position invariable. Almost all fans use sleeve bearings, which in a typical position, where the bearing is perpendicular to the ground (think front case fans), are both quiet and long lasting. However, when placed parallel to the ground (think your power supply fan), they can become noisy and fail prematurely. The SSO2 bearings in the NF-A14 PWM are unaffected by position, making these great for fans that are mounted at the very top of your case or radiator. 4: Long lasting. In large due to those superior bearings, these fans will last much, much longer than your computer will be relevant. You will easily get 4 or 5 entire computer builds out of reusing these fans, and given that fan technology doesn't advance at the rate that other computer technology does, you could conceivably reuse the same fans for 10 years or even longer. All in all, the NF-A14 PWM is my favorite fan within Noctua, including their higher speed iPPCs (which I also own) and their smaller fans.

So quiet I thought I did something wrong

I purchased these to replace the Corsair fans that came with my h115i liquid cooler. I do a lot of 3D rendering on my overclocked 6800k, so was constantly dealing with loud fans on my radiator as they ramped up to 2000rpm to keep the cpu you at an average of 62C. I expected these things to be quieter than the Corsair stock fans, but I had no idea they would cool my cpu while maintaining a lower rpm. At 100% load with the Corsair fans I was around 2000rpm at around 62C. With the Noctua fans, I am now at around 52C running at 800rpm at 100% load. So not only are they running at less than half the speed over the Corsair fans, they are keeping it 10 degrees cooler. Amazing. I can't recommend these enough, especially if you do a lot of cpu intesive work like video or 3D rendering. I'm considering replacing all my case fans as well.

Don't judge it based on color, amazing fans!

Two things stick out immediately about Noctua fans: 1. The colors 2. The price While I personally don't mind the coloration of their fans, they are unquestionably quite an.. unusual decision for a fan color. In addition, these fans are quite expensive - but you get what you pay for. These are top-of-the-line fans with exceptionally low noise output, amazing performance, and great build quality. These fans are made for people who want the best fans they can put in a case and aren't afraid to flash their cash for it, and aren't concerned with their fans lighting up and turning red/green/blue or any combination thereof. Installation is easy, fans have rubber feet on all 4 corners to help dampen vibration and keep them still against the case. The fans themselves are quite quiet, and even on full RPM they produce a low-pitched "woosh" rather than a high-pitched "whine" of lower quality fans. Noctua does offer "redux" fans in a more mute and fitting grey rather than tan and brown, HOWEVER the redux fans ARE NOT THE SAME as these fans. I ordered a few for a family member's build, and the quality on the redux fans is significantly worse than these fans. They still preform well, but aren't even close to these in terms of build quality. Just something to keep in mind.

I love Noctual fans and finished replacing all (-1) old fans with them

I love Noctual fans and finished replacing all (-1) old fans with them. Pros: - last "forever", and they do that without getting noisy (check about the types of bearings... these are the absolute best for the application. - very silent unless you need to push it past 70%. Then the noise is not whinny but "whooshy" of the air moving. - no LED on them (I don't like to pay for LED I don't use. I need my case to not be Christmas lights demo all year long). Cons: - price. Now if you are like me and keep your cases forever, paying once for 5-10 years will be cheaper than buying fans every 3 years when they start to be noisy. BUT if you change your case on a regular basis, say every 2 years, you do not need these fancy fans unless you want "silent". - colors. Black would be even better for me than Noctua brown... Noctua "Chroma" are insanely expensive, not that great looking and are not better. So as I only care about performance (acoustic, life, and air flow), that's not worth the extra cost to me. Case: Coolermaster HAF-X (I have other computers and likely old Noctua fans review, still working great 5+ years later). I have this fan as the rear exhaust fan. I have 3 20cm Noctua fans (one likely bought from Amazon years ago) as one intake in front of the HDD/SSD, one side intake for cpu and graphic card, and one exhaust on the top. In this specific case, the 20cm Noctua fans (not available on Amazon, had to get some kind of egg to get them...) do not fit. They have to be cut and the case cut a bit with a dremel, or do like I did and zip-tie one fan in the case but hanging from the top (inside). Hard to explain, but without fan nor case modifications, this fits. So I have only one exhaust fan on top, but that's the way the case was sold, and the fan is just where I need it, above the cpu/mb mosfet/graphic card where I want the airflow, and not on top of the BR Burner that sees no use.

Significantly quieter, show up in fan control interfaces, but I had to make mounting adjustments.

The back fan that was stock with the computer case ran sometime, sometime didn't...it was just about done. Plus, even though it was a four-pin fan and was powered by the motherboard, it wouldn't show up in either the motherboard's UEFI BIOS Utility, nor in a third party fan monitoring program. Thus, I couldn't monitor the fan, and didn't know if it was being controlled by the motherboard or not. So, I decided to replace it with this fan hopefully reducing fan noise and providing fan monitoring and control too. This fan comes with flexible, sound dampening mounts that are a great idea. They isolate the fan from the case. But I simply didn't have room in the case to pull those mounts through the case's mounting holes and then through the mounting holes of this fan. So, I had to resort to using the screws (included) to hold it in place. The case's top fan was still working. Here again, it was a 4-pin fan attached to the motherboard. But, it too wouldn't show up for monitoring purposes. So, I replaced it with Noctua NF-A20 PWM, Premium Quiet Fan, 4-Pin (200x200x30mm, Brown). However, I had a problem with this fan's overall size. The top of the computer case is removable, making replacing the fan an easy job. It was easy to push/pull the elastic mounts through the fan mounting holes. However, the top of the case wouldn't snap back into place. The top is held in place by some extensions off of the top that snap into holes in the top of the the case. Those extensions couldn't move past the fan's enclosure. This fan was just wider than the stock fan. So, I used a small cylindrical grinding attachment in my Dremel tool to remove small amounts of the fan encasement that were blocking the top's extensions. After that, it the case's top snapped right into place, and I was ready to test both fans. I started my computer - and the fan's sounds were appreciably reduced! Plus, both fans showed up in my fan monitoring utilities. Very pleased! Thinking about replacing one or both of the case's front mounted 200mm fans.

Initial impressions good

This is a very quiet fan, which I am using in place of the top-mounted fan that came with my case. I like the short lead that is connected directly to the fan: it reaches to the connector on the motherboard without leaving an excess length "flapping in the breeze." The included extension and splitter leads, and low-noise (speed-reducing) adapter should enable its use in a wide variety of cases. The fan came with a set of silicone-rubber anti-vibration mounts in addition to the conventional mounting screws, but I used the screws to mount this fan. Maybe it would be quieter still with the silicone-rubber mounts. and I may yet try reinstalling it with those instead. I am pleased that it does *not* have LEDs that I would have to try to find some way of disabling. Time will tell as far as durability is concerned, but the 6-year warranty is comforting.

Quiet and effective

I purchased this fan to use as intake in my Fractal Meshify C case and so far it has performed beyond my expectations. It's very quiet and keeps my temps low even while playing fairly demanding games like Warzone. Beyond the color, my only issue with the product was the anti-vibration mounts. While they work well, they are rather difficult to install and I had to leave one out as it was impossible to pull through due to the angle. Also, my kit didn't come with mounting screws as specified in the product description. Despite those small inconveniences, I'm happy with my purchase and would highly recommend this Noctua fan. Edit: I found the mounting screws hiding in the box, so scratch that!

Fan perfectly quiet, but moving air can still make noise as it passes through grills on case.

Fan is really quiet even at full speed, but I get this rushing air noise, which is unavoidable if your case creates resistance to the airflow. Started to notice the noise around 1350rpm so i keep my fans at 1300rpm most of the time. The included rubber anti vibration mounting pegs don't work well with mounts that have slideable mounting holes. There's not enough grip to keep the fans from sliding down. Should work well enough with actual mounting holes that wont allow the rubber to slide down, I haven't tried though. Included screws were silver colored, used my case screws which were black and matched the case. Screws are meant to cut through the holes to create a thread. Fans come with un-threaded screw holes.

Silence is almost golden.

This review is for Noctua 140mm Premium Quiet Quality Fan with PWM (four connector plug) It's not often that you get to truly enjoy a piece of hardware in IT - apparently the Austrians know how to make that happen. Even before I had received the fan I already had an email with contact information in case there should be anything wrong with the fan. Then the moment arrives when you hold the the nicely book style packaged fan in your hands, glance with joy over the included cable and mounting accessories before you finally get to install it. Welcome to acoustic heaven on earth. In this particular case two Corsair stock fans included in the H115i water cooling system were permanently retired due to their annoying sound habit and replaced by two of the Noctua fans. Silence - or the absence of annoying sounds is difficult to describe - unless you were fortunate to ever be in Antarctica. As a long time member of silent pc - I wholeheartedly endorse these fans - even if they have an odd color (maybe working towards golden) and no lights.
