Summary: The price was right. For Noctua's that is. I bought 4 for 73.96 from Cool tech PC. I replaced 4 fans that came with my Cool@#master Cosmos case that were a couple years old. There was no difference in sound at all. Airflow dropped a little too as I cut down the rpm's.
Summary: Pros: Good quality, moves decent amounts of air. The sound it makes is not a high pitched whine. Cons: Not as quiet as some of my other fans. Ugly color scheme. For the money, I was expecting it to be quieter. I will stick with Scythe brand fans next time.
Summary: I bought one of these to replace the loud stock fan in a DroboFS NAS unit. I should have paid more attention to the details - while this fan is indeed silent, it's also a very poor performer when static pressure is called for.
Pros: These are pretty solidly constructed, you can tell Noctua cares about the details. Even the packaging is nice. They are quieter than stock fans.
Cons: I bought a couple of these for a build, to replace case fans that come with the Antec P280. They were quieter, and I would've been happy, had I not also bought some Nexus fans. At the same speeds, the Nexus fans are noticeably quieter. They do have a loud hum at max speed, too. Yes, I'm being pic...
Summary: There are other options, but they're pretty much all terrible. Some brands outright lie with their statistics. Some don't need to lie, their products are bad enough. Noctua doesn't have these problems, but they don't have silent fans that push a ton of air, either.
Pros: Yeah, I'm a noise snob. I've been searching for case near-silent case fans that actually push air for a long time. I'm sorry to say I haven't reached my goal with these NF-S12B FLXs yet, but they are the closest I've gotten out of ~10 different fans. It's for this reason that I'm giving 3 eggs. T...
Cons: The price. Ouch! More than just the price though, these guys have a rather annoying hum at ~950 RPM and higher, and that's with the noise-dampening rubber hooks. You really need to slow them down below 900 or 800 RPM to gain quiet.
Summary: Contrary to most opinions I really like the colors. There is just something about it.. they are soothing :D
Pros: Noctua quality Extremely quiet and good air flow.. not pressure but flow.
Cons: Low static pressure!! This is not the fan you want to use on your new CPU cooler; it is also not very good as a intake fan if you have filters or tight mesh work and whatnot. Go with the NF-P12 for situations like that; it will be worth the extra few bucks and you can turn it down some if you nee...
Excerpt: Прежде всего стоит отметить, что я очень требовательный к шуму комппонентов компьютерной системы пользователь. Это нужно учитывать перед прочтением того, что я напишу ниже.
Pros: 1. Качественный подшипник
Cons: 1. С U.L.N адаптером иногда может не стартовать., 2. Антивибрационные крепления на порядок менее удобны чем те, которые Zalman ложит в комплект к 50-гривневым вентиляторам. На них трудно закрепить вентилятор, но их легко порвать., 3. Для сборки абсолютно бесшумного ПК подходит не лучшим образом.
Excerpt: Начитавшись положительных отзывов и по причине отсутствия ноизблокера рискнул взять. Что сказать, не такой он и тихий как его рисуют, на 1200 гудит ощутимо, поток да крут, но этому потоку мешает сетка, её надо бы сразу срезать или выкусывать, но при наличии маленького ребёнка это невозможно.
