Noctua NF-A6x25 PWM, Premium Quiet Fan, 4-Pin (60mm, Brown)

I like'em! (see pics) Got two for my pc (HP P7-1010) to get more air moving in there. Also bought one of the 40x40x20 little guys to get some air coming in the side vent on my tower. These things do not move very much air. But that's OK, it's all I could really do for my tower. And who cares about the color? I think they look awesome. If you want more air movement I would get the Bgears fans. Those things are about 50% more powerful than Nactua's. I know these fans are rated at 3000RPM, the Bgears I have are rated at 5000rpm and they destroy Nactua's fans. BUT! they're louder. Not annoyingly loud, but definitely noticeable. But cmon you can't spin at 5000rpm and be silent... If you look at the picture of my side panel you'll see what I did. My pc was bought all in one at Staples back in 2011. I've upgraded everything possible. Best cpu my mobo will take (AMD Phenom II X6 1065T 95watt) (32gb RAM Kingston Hyperx Fury) (2gb EVGA Nvidia GeForce gtx 750 Ti) (two Solid State Drives by Western Digital, a 500gb, and 1TB) (Seven USB 3.0 ports (pcie card)) (an Antec A30 Heatsink fan) This thing is my baby. I know it's not a custom build. But I've had it for almost 10 years and it runs fine still. I can run almost any game as of 2020 without issue. Audio and Video editing (Pro Tools & Sony Vegas Pro HD) run flawlessly. I've turned a manufacturers system into a monster. And I hope to get another 10 years out of it. But I do plan on finally building my first custom build next year. Sorry for the rambling lol I don't know why I do this on reviews lol Nactua is probably the best in quality. I recommend you buy these bad boys. Or whatever size you need. Get'em!

I am a skeptic by nature and I have been very disappointed in the past buying aftermarket fans to replace the ridiculously noisy stock fans they put in equipment. I saw reviews saying this fan was good, and generally it was regarded as the real deal but I've seen that before. I ordered some of these (and other sizes) expecting to have to cut some neoprene strips to adhere to it to prevent vibration noise between it and the case. When this fan arrived the first thing I noticed was that it came with rubber/sorbothane attachment points. Then I noticed everything else that came with it. Usually you buy a fan and all you get is the fan - you need to get extenders yourself, pin converters (3 -4, or 4-3) yourself, etc. This fan came with everything: extender cable; pin converter; rubber feet; an extra cable with an inline resistor for lowering the voltage/speed/noise of this or any other fan you want to plug it into. Most of all the quality of everything was absolutely top notch. I was blown away before I even hooked the fan up - then I installed it using the supplied rubbers and it was true to form. This fan produced so little noise I had to turn everything else in the room off just to gauge it. If someone tells you this fan is too noisy it's because they didn't mount it correctly, or are running it un-throttled. Even at full speed this fan was the quietest I've found and the full speed noise was reduced with the in-line resistor.

This fan has worked great! I'm doing this review after about 3 months and it has been fantastic at both keeping the temperatures down in my small form factor PC and doing whole whisper quiet. The included rubber mounting pins act as screws and ensure that no matter what case you are putting it in they will cover you. Highly satisfied!

I used the Noctua NF-A6x25 PWM as a replacement for the noisy fan on my QNAP TS-212. The original fan had failed and I replaced it with a Delta AFB0612VHC also from Amazon which did not last six months before it started to make noise as well. Back then I had considered the Noctua fan but did not buy it because it was too thick -- the original fan was 0.6 inch thick and the Noctua fan is 1.0 inch thick. This time I decided to get the Noctua fan and try to make it fit. The fan could not be mounted inside the enclosure but came with four "anti-vibration mounts" made of silicone that allowed me to mount the fan outside the enclosure by just pulling the "anti-vibration mount" peg through the original fan screw holes. The fan is mounted outside the enclosure and is VERY QUIET and keeps the system cool. I had to drill a small hole on the plastic case to allow the fan wire to pass inside the enclosure. The QNAP is able to control fan speed automatically and the fan power and sensor match QNAP pin-out. I had bought the Delta fan because it was the same model as original fan but turned out to be junk. The Noctua fan is highly recommended by others so I expect it to last much longer than the Delta unit.

I use two NF-A6x25 PWM on my DELL T5810 to help cool the internal. I initially use 4 pin to 5 pin adapter and connect the two FAN to the HDD fan header but it turn out the speed is too slow to be useful. I end up buying SATA power to two 4 pin fan adapter (this will make the fan run at full RPM as it connect only the two power pin @ 12v) so I use the Low noise adapter cable supplied included in the noctua fan to make the fan run at lower RPM instead of full RPM. My setup is one fan at the back for exhaust and another one in-front of the CPU to push more fresh air into the CPU. My CPU temperature is 3-5c cooler, for light work (browsing / watching youtube will be 35c-40c) with room temperature of 28c. The two noctua fan are practically silent and I didn't notice any noise increase by installing them.

Wentylator jest bardzo cichy i mega wydajny. Nie jest tani ale warto zainwestować w jakość, bo to się opłaca.

Pues no hay mucho que decir, es algo caro pero es simplemente un excelente ventilador, desde el empaque puedes ver la calidad de primera, con muchos extras como un cable divisor, una extensión y un cable para limitar la velocidad por si requieres que sea aún más silencioso pero dudo que a alguien le haga falta porque en verdad es super silencioso considerando que es de 3000rpm, su único "pero" es que es algo grueso.

Wenn immer möglich, verwende ich für CPUs Lüfter von Noctua. Diese haben sich aufgrund ihrer Qualität bestens bewährt. Sie arbeiten auch nach mehreren Jahren noch zuverlässig. Trotz hervorragender Kühlung gehören sie zu den leisesten ihrer Klasse. Obwohl ich diesmal nur einen kleinen Zusatzlüfter benötigte, entschied ich mich auch diesmal für ein Noctua -Produkt. Nun sorgt er in meinem Netzwerkschrank für einen kleinen seitlichen Luftstrom, da sich der ursprünglich lüfterlose Switch nach Einbau zweier SFP-Module doch sehr aufheizte. Die Lösung ist zwar optisch nicht allzu professionell, erfüllt aber voll seinen Zweck. Fairerweise sollte man erwähnen, dass die Lüfter nicht zu den preiswertesten gehören. Doch aufgrund ihrer Qualität ist auch hier das Preis -/ Leistungsverhältnis völlig ok, zumal Schrauben, Gummiverbinder, Anschlusskabel und Kurzbeschreibung zum Lieferumfang gehören.

Supergood quality...
