NF-A12x25 G2 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.

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

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!

Bought one of these for a single exhaust fan on the top of my case after having great experiences with Noctua fans in the past. Noise wise they are excellent, allowing you to run them at higher RPM's than some other fans and they have no hum at low speeds unlike the Arctic fans I tried. They're expensive for single fans but they come well packaged with everything you need (adapters, extensions etc) and they are genuinely built to last and come with 6 year warranty from Noctua, they'll last for multiple builds and pay for themselves over time.

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

Very high quality design and very low noise output. When I need more, I will buy these again

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.

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!

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.

Really good product not noisy and it helps a lot with the temperature

動いているか心配になるくらい静かです。 風も充分に流れてるの素晴らしいファンです

Super matis, un peut cher comparé à certains concurrents mais top niveau qualité, efficacité et surtout hyper silencieux pour le volume d'air, en plus livré avec rallonge + répartiteur en Y ! Seul reproche : les parties gainées sont très rigides ce qui complique un peu le passage des câbles, mais le reste fait vite oublier ce désagrément.
