NF-A12x25 G2 PWM, High-Performance Quiet Fan 120mm | High Airflow & Static Pressure, Low-Noise 25mm Thick Fan for Coolers/Radiators/Cases, Rich Accessory Kit, 1800rpm 4-Pin PWM

They're incredibly silent, move a load of air, and the static performance for my AIO is brilliant. I've installed 6 inside of my Fractal North (3x Upfront, 1x Exhaust, and 2x as exhaust on my 240mm AIO). They are expensive but they are worth it - they don't have any low annoying whine noise and Noctua are notorious for their incredible customer support so the reassurance of a strong warranty is worth that little bit extra.

powerful and silent

Lower temps on CPU heatsink than ever before, and much quieter.

I swapped out some BeQuiet Pro 4s which were on medium speed setting, Wow, these are quieter and shift more air, My pc is running 6* cooler just by swapping the fans, I got a pair of offset speed and a single one and they work well as a 2 intake and 1 exhaust, highly recommend

Incredible. Worth every penny. I was hesitant to spend so much on each fan, but I really wanted a silent build. I swapped 3 of these onto an Actic Liquid Freezer III (already a quiet AIO cooler) and at 20% fan speed they are literally silent. Even maxed out they are quiet fans, but this combo will cool a 9600X running a stress test at barely 50% fan speed. The loudest part of my build is now the AIO pump, but due to the efficiency of these fans I was able to turn that down too so at idle the PC is now completely silent. The brown isn't to everyones taste, but they are hidden insde the case!

It is a Noctua fan, you get what you pay for, seems like a pretty big upgrade from the old style A12 I already had, and works well enough under challenging restrictive airflow paths that the high pressure Noctua industrial I also tried on a few dense fin stacks in comparison wasn't needed.

Really quiet and pushing the air nicely. If you are not bothered by the colours, probably the best choice. Expensive but worth it!

I purchased three of these amazing fans and I can say that this is another level of cooling and noise, absolutely perfect

Wat kunje hier nog van zegen buiten the best beter wort het nie dit wort fan nummer 6 en scheelt op de watercooling alm10 graden top

I got this fan to replace the stock 120mm fan on an AIO water cooling system. The design of the Noctua G2 fan is perfect for this application, since it's design helps with static pressure and keeping airflow up through a radiator without adding a ton of noise. At 1800rpm this fan is very slightly louder than the fan it replaced that ran at only 1500rpm, however Noctua included a short fan speed/noise reduction cable extension that would drop the top speed of the fan down closer to 1500rpm which would also reduce noise. In operation with the computer fully loaded with a stress test, this fan dropped my cpu temperatures by about 5C which is really good for just a fan swap. The fan came with a few really nice accessories too. Each corner of the fan has a little rubber mounting insert to reduce vibration noise, and Noctua also included a full size rubber seal that goes around the entire fan to help it seal up better against water cooling radiators. I used this seal, and installation was very simple. All fan cables were nicely sleeved to improve the looks of the wiring. The packaging also included the fan speed/noise reducing cable extension, a plain fan cable extension, and a fan cable extension with Y-splitter. There were a few other items as well, such as mounting screws and some rubber mounting pins that could be used instead of screws when mounting to a metal case as an intake or exhaust fan. All in all it was a very nice accessory package and it at least partially explains the premium cost of the fan. The only real drawback to this fan was the price - At the price I paid, it was actually more expensive than the entire AIO cooler I am using it on and that's not awesome. Still, I wanted more cooling performance than I was getting with the original AIO fan and this Noctua G2 fan certainly performed up to my expectations. Recommended!

Great fan! Super quiet, accessories and pkg were excellent. Cooled my PC very nicely for the amount of noise it makes! Highly recommend!

C'est fait par des experts en refroidissement PC: silencieux et performant. Il y a aussi tout ce qu'il vous faut dans la boîte aussi.

To są po prostu rewelacyjne wentylatory. W komputerze syna wymieniłem wszystkie 6 sztuk — 2 na chłodnicy, 3 na wlot i 1 na wylot. Stare wentylatory miały już po 6–7 lat, a część nowszych była po prostu tańsza i niestety bardzo głośna (około 38–40 dB). Po zamontowaniu Noctua różnica jest ogromna. Nawet przy pełnym obciążeniu procesora i karty graficznej komputer pozostał zaskakująco cichy. Szczerze mówiąc, byłem w szoku, jak dobrze to działa — poziom hałasu przypomina teraz mój komputer z chłodzeniem wodnym. Ogromny szacunek dla Noctua za jakość wykonania i kulturę pracy tych wentylatorów.
