Noctua NF-A14 FLX, Premium Quiet Fan, 3-Pin (140mm, Brown)

Noctua makes possibly the best fans on the market. I have never had a bad experience with their products and they offer a 6 year warranty on their products. Their customer service is also amazing. Most fans will not last you that long; most fans stop working after 3-4 years if you are lucky. This is the reason you buy these fans because you know they will last you a long time and you always have the warranty as a backup option in case it dies out.

Great fans, I put six of these in my Fractal Designs R4 and they are quieter than the three Fractal 140mm fans they replaced. Top quality fans that are well worth the money.

Awesome and quiet

The stock fans that came with my Air-540 were great. Moved tons of air and kept everything nice and cool. But it sounded like a 747 taking off every time I turned it on. After installing the new Noctua fans I could immediately notice the difference. Now the mechanical HDDs are the loudest thing in the case.

Perfect

This fan has a great build quality: from removable rubber corners to deaden vibrations, rubber screws, regular screws, three different cords from pwm to extensions. This fan has it all. On top of all that its so silent. I am working to replace the other ten fans in my case with only Noctua from now on.

A++++. Great RPM, low noise, high air movement. Highly recommend.

I purchased 3 of these fans to replace a few old Corsair fans that were in my case...and although they are only fans, my GPU temps have gone down by about 4-5 degrees and the overall cooling of my system is much better overall now. Solid product with solid results, cant go wrong with these.

Very quiet fan with awesome flow - Ive had zero thermal issues with this computer!

Easy to install quickly and very quiet
