Summary: I bought these because Noctua has a stellar reputation. The color scheme is... well, let's be honest, it's not pretty. But I didn't buy them for looks. I bought them because they move A LOT of air. And they do! And they're surprisingly quiet for how much air they move.
Summary: It's good, but it's not a panacea. It actually -does- move more air, which is good. But it's not -really- much quieter than an Antec fan at the same RPMs, but there's no free lunch in physics, right? So yer CPU should run cooler more than -quieter-.
Summary: The fan cools great I have it set as a side case fan. Its a bit noisy on full so I have it set to low and it still puts out plenty of air. I gave it a 4 star for the noise I think it should be a little quieter for the price.
Summary: silent, blow a good amount of air compaired to the nzxt 140 fans that come with the switch 810 and more than the Cooler master essentials 140 1000 rpm than i own too. as always with noctua, great bundle, great quality. well, with the price you pay, at least.
Summary: When I first built my computer, I ended up using the 6 120mm fans that came with my case. The cooling was great, but the sound was like an airplane taking off. After several years of putting up with this, I decided to do something about it.
Summary: The fan looks great, feels great (build quality) and for the most part runs great. Can it get a little loud? Yes. Does it push a good amount of air at 100%? Yes. If you use the adapters or fan controller to get it completely silent, it doesn't push as much air.
Summary: Very nice. Brought about a 10 Centigrade difference in temperature in my Define Mini. Will definitely be getting more for my Hyper 212+ (if they can even be mounted on it). What I was surprised to find out was that the fan can actually mount in a 120mm fashion due to its rounded shape.
Summary: First, the bad: At least with my particular Noctua, the 140mm fan does not like to run vertically. Even at full speed it struggles to start. I have adapted to this and just use it for horizontal applications, but the option to mount it vertical would be nice. Hence the one star removed.
