NoctuaNF-P14r redux-1500 PWM, High Performance Cooling Fan, 4-Pin, 1500 RPM (140mm, Grey)

for the money the anti vibration pads should be included, not an additional purchase.

These fans are just great i got 2 140mm and 2 120mm and the quality is just unmatched to any other fan. The noise is super low now the loudest thing in my system is my old hard drive.The air flow they push is very good and they also look way better than the standard tan and brown colours. Overall a great buy no complaints

Great products for keeping your components call which means the fan does not have to spin fast and noise levels are low. This is a pwm fan so spin rate will depend on on control from the motherboard

Yes, as some of the other reviews are stating, these are not absolutely the quietest fans you can but. They are of course going to be louder than a 120 mm fan. It's a 140 mm fan moving a lot more air... that's the whole point. There are undoubtedly some other 140 mm fans that will be quieter too; if you want cooling performance as good as this but with a bit less noise, you probably want to look at either an NF-A14 or NF-A15 depending on what you're using it for (NF-A14 for case fans, NF-A15 for coolers, but they're exactly the same performance specs in a differently shaped plastic frame). The A14/15 is both slightly more effective cooling and slightly quieter because it's basically the flagship 140 mm fan Noctua does just now and the redux is last-gen tech by definition.NF-P14r redux:25.8 db/A noise | 133.7 m³/h airflow | 1.91 mm H2O static pressureNF-A15 HS-PWM:24.6 db/A noise | 140.2 m³/h airflow | 2.08 mm H2O static pressureI've been using one of these as a case exhaust fan for years and recently switched it into the middle of my D14 cooler, replacing the NF-P14 FLX I had previously put there, and it slightly increased noise but noticeable improved my CPU temperatures both under load and at idle. I added a second one, replacing the stock P12 120 mm fan at the front of the cooler, and the same thing happened again, as expected.I've been buying Noctua stuff ever since the company first appeared back in 2005. Every fan I've switched or added into every system I've built (for myself and for others) for the past 15+ years has been some Noctua or another. I've also found their thermal paste to be very good. I have the distinct impression that this is a case of more or less getting what you pay for; if you want super-premium, buy their latest stuff. If you want *almost* the same kind of performance at the cost of slightly increased noise and a fairly significantly reduced price (and arguably slightly less pleasant aesthetics with this light grey colour scheme), buy a redux. That's pretty much all it comes down to.

I have used a fair amount of fans before but this is the first time using a noctua fan. I can honestly say that it is the best performing fan I have ever used going to replace all the fans in my main system from Lian-li fans to the 120 versions of this.

I've just had one of these replaced by Amazon (May 2021) after finding the first one to have completely unacceptable levels of motor or bearing noise (almost certainly the latter as I tested with pure DC, no PWM circuitry involved) even at 7v or c. 800 RPM.I already have three 120mm redux high-speed fans (two-tone grey like this one, square frame) and the NF-A15 140mm on the Noctua NH-U14S cooler in my PC (also have a couple of low speed 120's I've tested but never installed) so I knew what shoould be expected from this one.Thankfully the replacement is much better (arrived the day after submitting the request - Amazon has its uses!), only the aerodynamic noise of the blades can be heard.Pricing is all over the place at the moment (seems to vary day by day), but assuming £12-14 AND that they meet their spec (in terms of noise) they're excellent value, but I'm giving the model 4 stars (I'd make it 3.5 if I could) on account of the apparently less-than-perfect QC.

Excellent quality case fan, good value for money.

PerformanceThe Redux range of fans aims to have something available for everyone. They come in multiple sizes, all with 3-pin and 4-pin options and their unique design allows them to offer a great deal of airflows with the least amount of noise they can. Obviously, the higher the RPM, the noisier the fan will be but unfortunately for us, smaller fans will need this to output a sufficient amount of air. The Redux range is also designed to help cool cases and/or radiators thanks to their unique design. During my testing, I was blown away by the amount of airflow they created and the 120/140mm fans while audible, weren’t overly noisy or irritating. Noctua is known for performance and the Redux range is nothing short of Noctua’s reputation.DesignNoctua took fans concerns over their original colour scheme into mind and as such, the consumer market was offered the Redux range of fans which as we have seen, are grey on grey and come in multiple sizes. One of the things I was happy to see was a round version of the 140mm and while it would have been nice to see something similar in the smaller sizes, it’s understandable why Noctua didn’t make those as well. The Redux range is designed to Noctua’s high-standards and come backed by a 6-year warranty if you had any concerns about Noctua’s engineering.ValueThese are definitely not the cheapest fans on the market and we wouldn’t want them to be. When you make cheaper more budget stuff, something has to get cut somewhere and it is normally the quality of the product. Noctua products offer good value for the money through their amazing performance, which again, is backed by a 6-year warranty. Value is very subjective as I always say, but as long as you don’t take it to mean budget than the Noctua Redux fans offer great value, plain and simple.Disclaimer: I received this fans in exchange for an honest and unbiased review.
