Noctua NF-A4x20 40x40x20mm FLX 3 pin 5000rpm Case Fan/Case Cooler

One if not the best engineered cooling fan one can buy today. Bought this to augment the stock NOCTUA heatsink installed in my computer. Works silently and I see a reduction of almost 2 degrees cpu temperature. Highly recommended.

Installed two of these on my graphics card. It astonishingly reduced temps of my PC by atleast 20-30 degrees. Huge improvement. Well worth the cost. Thinking of changing all the fans to Noctua!!

no noise problem at higher rpms, overall great performance, 2-3 degree cooler temps when used on heat sinks.

I have replaced stock fans from my Unifi Ubiquiti USG Pro and I here the sound barely, before with stock fans I mom used to complain about noise while she was in other bedroom. Now no sound from the fans at all, for your reference I am not using any low noice adaptors. I will purchase two more to replace in 24 port PoE switch.

Completely silent till 75% load, very low noise at 100% load. Long lasting SSO2 bearing (6 year warranty). + PWM - Color of the fan (doesn't matter since it is placed inside the case).

Seriously, it is very quit and noiseless.

Arrived without seal No packging, no tape, just pre opened noctua box, fan blade were touched by oily fingers, fingerprint How can one send for delivery such item which is costly and fragile. Amazon you are loosing faith in customers. Any one on the way can exchange the fan with a refurbished or non working fan I am not happy with packaging, and genuineness of the product.

5.5 years after using Cooler Master Hyper 212X, It is time to finally retire the rattling fan. It has started making noise and vibrates a lot even at 1000 RPM which is 50% of its max RPM. That Cooler Master Heatsink is flawless and will last another 5 years easily. And what better fan to replace it than the legendary Noctua NF-F12 static pressure fan. In terms of RPM, this runs at a maximum RPM of 1500 while the Cooler Master bundled fan can run at a maximum of 2000 RPM. However, anything over 1200 RPM and Cooler Master fan used to sound like a jet. Noctua on the other hand is dead silent even at 1500 RPM. Temperature is reduced by 2 ~ 3 degree only but the fan noise has reduced a lot. If you can afford then do buy the Noctua NH-U12S CPU fan for upto 95W Intel CPUs.

Se você procura algo durável, que ventila mesmo sem fazer ruido, pensa em algo bom, é esse Fan.... Vai lá, compra sem medo!!!

Es Noctua, ya sabemos que es calidad y silencioso

What a waste of money! Started up with a high pitched sound And never stoped until I turned off the PC..

Vraiment top. Je les ai pris car j'en avais marre d'attendre la version G2. Alors je ne peux pas comparer avec la nouvelle version mais dans mon cas; ces 7 ventilos font leur boulot et en silence Avec le coupon je suis a 27€ par ventilateurs, et les g2 seront surement à 40 quand ils sortiront (quand il en faut 7 ça fait une bonne différence de prix) Je les ai mis dans une ANTEC FLUX (version normale) et ça tient mon i9 9900K a 88 degrés sout OCCT en CPU Stress Test ce qui est une bonne perf vu que ce CPU a tendance à chauffer "un tout petit peu" :)

流石と言えるレベル。静音で振動も感じられなかった。価格が安ければPCファンを全部これにしたいです。
