After years of PC cooling fans remaining much the same, this last year has seen a few manufacturers pushing to put a spin on the traditional fan design to help increase performance without increasing noise. One of the first fans that passed through our hands with this design was Silverstone's AP121 - a quiet fan with a very focused exhaust that made it great for CPU cooler and radiator applications. After a year without much changes to their fan lineup, Noctua has now debuted their own entry into this market - the NF-F12 PWM. The NF-F12 is a PWM controlled fan with a very unique looking design which is supposed to better focus airflow and reduce noise, all from a fan which also draws considerably less power than most 120mm fans do.
PC散热经过多年的改进。其风扇仍然大同小异，去年已经现出了不少厂家把一种转动应用到传统风扇的设计上，在不增加噪声的前提下以帮助风扇提高性能。我们第一次亲自测试的这种设计是Silverstone's AP121－－一种有很好集中散热而且安静的的风扇。但是在经过一年后的今天。他们的风扇还是没有让CPU散热器和风扇应用变得更好。现在，猫头鹰在这个市场推出了他们自己的产品－-NF-F12 PWM。NF-F12是一个具有非常独特的外观设计的PWM控制风扇。并且能够更好地集中气流和减少噪音，而且他比一般的120mm风扇将节省更多的功耗。

Features:
The front of the NF-F12 box is white with a wireframe rendering of the fan as the background - a similar design premise as we've seen on past Noctua products too. A small window on the front gives a teaser of the fan inside and shows off some of the unique design features also found on this fan.
特点：
NF-F12 PWM外包装和过去传统猫头鹰产品一样，前面是以白色风扇为背景的线框渲染设计，在其前面开了个小窗口。透过窗口可以看到里面这个风扇的大概独特设计。

Around back is a paragraph about the unique design and advantages of the NF-F12 fan. This paragraph is written in eight different languages, in case you're wondering why the picture below has so much text. But you're not done here - there's also two panels that open on the back giving far more information about the fan along with several different pictures and illustrations too. The back panels are held shut by little velcro pads - probably an unneeded touch, but when you're trying to sell an expensive fan, a good first impression will certainly help.
在盒子的周围及背后是一段关于NF-F12风扇的独特设计及其优势，这段文字是用八种不同语言写上的，这就是你为什么会奇怪怎么下面会有这么多的图片和文字了。你应该也不需要这么多语言内容。有二个打开的，而且上面有几个不同图片和插图的面板，上面描述了更多有关风扇的信息，，这种背面面板被小尼龙搭扣垫封闭，这些东西你可能都不需要用到，但是当你想买一个贵重的风扇时，良好的第一印象肯定会有帮助。

A complete specifications chart for the NF-F12 is found in the lower right corner of the first back panel - before the box is opened. The small size of this amongst the large amount of text from the paragraphs above actually resulted in me overlooking it a few times before catching it there.
在盒子被打开之前，在第一个后面板的右下角能发现一个完整的NF-F12规格图表。这种段落中的大量文字中涉及到的的小尺寸图片，事实上这些在在我刚接触他时都给忽略了。
Noctua has included a comprehensive bundle with the NF-F12 - more than I've seen with their previous fans. The cable on the NF-F12 is short - only 8.5" long - which saves a lot of space if you're near a fan header. However, if a fan header isn't nearby then a 13" extension cable is also included. A low noise adapter (LNA) is included, along with a PWM Y-Cable in case you'd like one PWM port to control two fans. All cables are sleeved in a very tight rubber mesh sleeving and all cables, excluding the one directly on the fan, have sticker labels telling you their purpose (stickers which don't stick very well to the rubber sleeving). Also found in the package are the regular rubber vibration absorbing mounts, metal screws and a short (to the point) installation/tips guide.
猫头鹰包含一种带有NF-F12的全面包装-而非我以前见过的风扇。这种NF-F12的电缆很短-只有8.5"长-当你接近风扇头的时候节省了许多空间。尽管如此，如果一个风扇头不在附近，还有一根13"长的延长线。随着一种PWMY型电缆应用在你所想要PWM端口控制两个风扇的情况下，包含一个低噪声适配器（LNA）。所有电缆都被套在一个非常紧密的橡胶网状套管中，不包括直接应用在风扇上，并且贴上标签，告诉你他们的目的（对于橡胶套管来说贴纸粘得不是很好）。在包装里也有常规的橡胶减震支架，金属螺钉和简短的安装/技巧指南。

The NF-F12 is a very unique fan which has a design that is much different than any Noctua fans I've reviewed in the past. To start, the blades have a much larger surface area and a significantly shallower angle to them compared to the NF-S12B fan I had last tested from Noctua. The NF-S12B also had cutouts at the end of each blade which were supposed to better channel air and reduce noise - those are also gone on the NF-F12 design. Spinning the fan around to the back will show you why.
NF-F12是一种非常独特设计的风扇，比以前我所见过的任何一款猫头鹰的产品设计都独特。首先，叶片和我最后测试过的猫头鹰中的NF-S12相比，具有更大的表面积和明显较浅的角度。NF-S12B在每个刀片尾部都有切口用来更好地通气和降低噪音，这些设计也应用到了NF-F12中。再绕到风扇的后面会告诉你为什么。

The back of most fans have 4 support columns that hold the motor in place in the middle of the frame. The NF-F12 has replaced that traditional support structure with 11 carefully angled 'blades' going from the center hub straight out to the outter frame. Noctua has called this their 'Focused Flow Frame' because this design helps keep a more focused airflow column exhausting out of the fan. There's three small notches on each 'blade' which serve a purpose best described by Noctua's adjective loving marketing team - "varying angular distance and vortex control notches" - a mouthful.
大多数风扇的背后有四根支柱将电机固定在中间。NF－F12已经取代了传统的支柱结构，由11个精确角度“刀片”的直出的外部框架中心枢纽。这就是猫头鹰著名的“聚焦循环结构”，因为这种设计有助于保持一个更为集中的气流排气风扇列。在每个刀片上有由猫头鹰营销队伍形容的最好的三个小的槽口，“不同的角距离和涡流控制槽口” – 小拗口。

By now you've probably notice that each corner of the NF-F12 is brown. These brown corners are actually rubber pads and  offer an integrated solution to absorbing vibrations between the fan and the surface it's mounted on. I like this design because not all places I mount my fans in can be accommodating of those rubber vibration absorbing mounts and still require screws to be used. This way, even if I need to mount the fan with a regular screw, I can still benefit from some vibration absorption. These rubber pads are easily removable in the event they hinder your installation.
现在你可能已经注意到，每个NF-F12的角落是棕色的。这些褐色的角落都有橡胶垫，并在风扇和安装的表面之间提供了一个综合的解决方案来吸收震动。我很喜欢这个设计，因为不是所有我安装过的风扇的地方都能够容纳这些橡胶震动吸收支架，仍然需要使用螺丝。这样一来，即使我使用一个普通的螺丝来安装风扇，我仍然可以受益于一些振动吸收。当阻碍他们安装的时候，这些橡胶垫很容易被拆除。

Also worth pointing out is the stepped inlet desin - i.e. the part of the frame that's beveled in on the front of the fan. Noctua's marketing team has simply dubbed this the 'stepped inlet design'. I'd be very curious to see test results showing if this design really does offer any performance benefit from a technical, not marketing, perspective.
值得指出的是加强入口设计，即在风扇前面的斜面框架部分。猫头鹰的营销团队简单地冠以“加强进气道设计”。如果这个设计真的不提供任何技术性能上的好处，我会很好奇地想看看最终测试结果的显示，希望不是仅仅为了营销受益。

The NF-F12 is Noctua's first PWM fan, and it's been a while coming. While other manufacturers have had PWM fans for years, Noctua has held out and has kept to shipping their fans and coolers with a pair of resistor cables - the LNA (low noise adapter) and ULNA (ultra low noise adapter). These cables give you the possibility of three distinct operating modes for each fan - stock, low speed or ultra low speed - which allows Noctua to provide solid specifications on each setting (such as airflow, noise, air pressure, etc). With a PWM fan, Noctua can now only provide minimum and maximum specifications because the PWM controller will dictate any number of fan speeds between the two. However, most PWM equipped motherboards will allow you to choose various PWM noise settings in the BIOS so you can customize your experience based on your requirements of noise vs. performance.
NF－F12是猫头鹰的第一个PWM风扇，而且已经推出有一段时间了。虽然很多年来其他厂家已经有了PWM风扇，但是猫头鹰已一直坚持使用他们原来的风扇，拥有一对电阻电缆的适配器-LNA（低噪声适配器）和 ULNA（超低噪声适配器）。对于每个风扇，这些电缆提供给你三种可能的操作模式-正常化、低速或超低速-允许猫头鹰在每个设置上提供坚实的规格（例如气流，噪音，空气压力等）。随着PWM风扇的到来，猫头鹰现在只能提供最低和最高转速规格，因为PWM控制器将决定任何数量的风扇二者速度的区别。尽管如此，大多数配备主板的PWM将允许您在BIOS中选择不同的PWM噪声设置，所以你可以根据你的经验。基于你的噪音和性能要求设置.

All the Noctua fans I've ever reviewed have had Noctua's SSO bearing. Without getting too technical, this bearing is designed and optimized for long life and quiet operation. After years of success with this bearing, Noctua has revised it and come out with the SSO version 2 bearing - found in the NF-F12.
所有的我曾经评测过的猫头鹰风扇有猫头鹰的SSO轴承，这种技术并没有进行太多的改进，这种轴承的设计和优化是为了延长使用寿命和安静操作。经过多年使用这种轴承的成功，很惊喜的发现在NF-F12中。猫头鹰已经使用了他们改进过的第2代SSO轴承。
The NF-F12 has a minimum rotation speed of 300 RPM and a maximum speed of 1500 RPM. Noctua gives noise level ratings of 18.6dBA with the LNA and 22.4dBA without the LNA. I'm going to assume the 22.4dBA to be a maximum noise level without the LNA, as the PWM controller will likely run the fan much quieter than that during regular use. Due to the focused flow design of the NF-F12, it has a very high static pressure of around 2.61mm/H2O. To compare that to a couple other fans, the Noctua NF-S12B has a static pressure of 1.31mm/H2O and the Nexus 120mm Real Silence Case fan, another of my favourites, has a static pressure of 1.2mm/H2O. Having a high static pressure makes the NF-F12 great for applications on heatsinks and radiators.
NF-F12有一个最低300 RPM的转速和一个最高1500RPM的转速。猫头鹰提供了噪音18.6dBA水平等级的低噪声放大器（LNA）和没有LNA的22.4dBA。我将假设没有LNA的22.4dBA，是一个最大的噪音水平，作为PWM控制器在运行过程中可能会比正常使用的风扇更安静。由于NF -F12的聚流型框架设计，它有一个大约2.61mm/H2O的非常高的静压。为了跟其他一对风扇比较，猫头鹰的NF-S12B有一个 1.31mm/H2O的静态压力和NEXUS120毫米真正的静音机箱风扇，这是我的另一个最爱，有1.2mm/H2O静态压力。具有高静态压力，在散热片上和散热器方面使NF-F12的应用程序更好。
Installation & Testing:
To test out the NF-F12 I'm going to put it against the NF-S12B and Silverstone AP121 fans. Comparison with the NF-S12B will show it's performance over a standard Noctua 120mm fan, and comparison against the Silverstone AP121 will show how it fares against a fan that's also designed to focus airflow, but using a different design premise than the NF-F12.
All fans will be tested on my Noctua NF-C12 CPU cooler and no other fans will be attached to this cooler but the one being tested. CPU temperatures will be recorded after 30 minutes of system idle and again after 30 minutes of load in Prime 95. Results are graphed and discussed below.
安装和测试
我要针对NF-S12B和Silverstone's AP121风扇测试出NF-F12。比较NF-S12B，将显示它的性能超过标准的猫头鹰120mm风扇，比较针对Silverstone's AP121将针对集中气流设计的风扇显示他的性能如何，但是前提是跟NF-F12相比使用不同的设计。
所有的风扇测试都将经过我的猫头鹰NH-C12 CPU散热器，并无其他的风扇连接到这个散热器，除了一个正在测试的。在30分钟系统空闲之后CPU温度将会被记录下来，在系统满载95负载30分钟后再重复。

With PWM disabled, the NF-F12 tied the Silverstone AP121 for lowest idle temperature of the bunch, coming in at 32 degrees Celsius. With PWM enabled and set to 'standard' mode, the NF-F12 came in at the highest idle temperature, only 0.25 degrees higher than the NH-C14 with the NF-S12B fan attached. As you can see in my chart above, no matter what fan I used, idle temperatures were all within a degree of each other anyway.
首先从禁止使用PWM功能来看看，NF－F12在最低空闲状态下和Silverstone's AP121一样。只有摄氏32度。随着PWM的启用并且设置为“标准”模式，NF-F12在最高闲置温度时到来，只是比加装NF -S12B风扇的NH-C14高出0.25度。正如你看到的我在上面的图表，无论我用什么样的风扇，闲置状态下的温度他们都会在一定程度。

Load temperatures saw greater variation than the idle temperatures did. With PWM set to 'standard', the NF-F12 came in with the highest temperature, 56.6 degrees, which is about 10 degrees higher than I achieved with any of the other fans attached. However, I will note that the NF-F12 was dead quiet at load when PWM was enabled. With PWM shut off, the NF-F12 once again took first place with a 45 degree load temperature, only 0.5 degrees off from the Silverstone AP121.
负载温度比闲置温度看出更大的变化。当PWM设置为标准，NF-F12就达到最高温度56.6度，这比我使用任何的风扇温度都高出10度。不过，我会注意当PWM启用时，NF-F12在负载时像死一般的安静。当PWM关闭时，NF-F12在负载时显示只有45度而排在第一位。比Silverstone's AP121都低了0.5度。
In terms of noise, I'd put the NF-F12 and NF-S12B on the same playing field, as it was extremely difficult for my ears to tell the difference between the two. However, as mentioned in the last paragraph, when PWM is enabled, the NF-F12 runs dead silent most of the time. PWM is an advantage that the NF-F12 has over other Noctua fans because it eliminates the need for the resistor cables which can only offer fixed fan speeds. Instead, PWM will allow the NF-F12 to run as quiet as it can until the extra cooling is needed at higher loads causing it to speed up. When all fans were run at stock speeds, the Silverstone AP121 came out ahead with the quietest noise level of the bunch. Looking at the performance I achieved with the Silverstone AP121 vs. the Noctua NF-F12 with PWM disabled, I might have a hard time justifying the higher price of the NF-F12 which is almost $10 more than the AP121. Looking at the numbers of these two fans, they both have the exact same noise level rating so the difference could also be impacted by subjective perception too (that is, how my ears hear the fans compared to someone elses ears, or expensive measuring equipment). Regardless of the specifics, I'd still like it to be clear that all three of these fans are amongst what I would consider to be the top 10 quietest fans I have reviewed to date and despite the differences over one another, they are all still very quiet overall.
在噪音方面，我把NF-F12和NF-S12B放在一个公平竞争的环境，因为我的耳朵很难分辨两者之间的区别。然而，在最后一段提到，当PWM能够使用时，NF-F12在大多数时候运行时会死一般的安静。PWM是一个NF-F12超越其他猫头鹰风扇的优势，因为它消除了只能提供固定的风扇速度的电阻电缆的需要。相反，PWM将允许NF-F12安静运行，跟额外需要在更高负载方面使其加快冷却一样。当所有的风扇在通常的速度运行时，Silverstone's AP121在噪音最小的方面的技术体现了。纵观我的Silverstone's AP121的表现与猫头鹰NF-F12禁用PWM的性能对比，我可能很难证明NF-F12比Silverstone's AP121贵了近10元。从这两种风扇的性能来看，它们都具有相同的噪音水平评价，所以它们的差异也可以通过主观感知来影响（也就是我的耳朵所听到的和别人的耳朵所听到的相比，或昂贵的测量设备相比） 。我仍然觉得这三种风扇是我迄今为止评测过的风扇中前10名中最安静的风扇，希望它们能够超过彼此的差异，他们现在整体上都表现得还很安静。
Other areas that the NF-F12 excelled at over both the NF-S12B and the Silverstone AP121 are in terms of power consumption and lifespan. The NF-F12, as I mentioned earlier, consumes only 0.6 watts where as the NF-S12B consumes 1.2 watts and the AP121 will draw around 1.08 watts. In terms of lifespan, the NF-F12 should last around 150,000 hours, which is three times that of the Silverstone, but the same as the NF-S12B which is based off an earlier revision of the bearing currently in the NF-F12.
NF-F12同时比NF-S12B和Silverstone's AP121表现出色的其他领域是在功耗和寿命方面。正如我刚才所说，在NF-S12B消耗1.2瓦和Silverstone's AP121将吸引约1.08瓦的地方， NF-F12仅消耗0.6瓦。在寿命方面，NF-F12应该持续大约150000小时，这是Silverstone's AP121的三倍，而相同的NF-S12B与NF-F12不同的是他的轴承只是早期的版本
To Conclude...
Overall, the NF-F12 probably has the most unique design I've seen on any fan today. Noctua has clearly taken a look at every angle and surface of a fan and found a way to tweak and optimize it for a specific purpose - providing strong, focused and quiet airflow. That is topped off with an included bundle that seems to cover the accessories needed for every possible use of the fan. The NF-F12 also excels with it's long life and extremely low power consumption (half that of most traditional 120mm fans).
结论
总体而言，NF-F12应该是我今天看到任何风扇中最独特设计的。猫头鹰已经清楚地看到了每一个角度和风扇表面，形成了为了特定目的的调整和优化方式 - 提供强大、专注、安静的气流。这几乎包括覆盖了所需要风扇配件的所有领域 。NF-F12高于其它风扇的地方还在于它的长时间的使用寿命和极低的功耗（只有传统的120mm风扇的一半）。
In my testing, the NF-F12 pulled out ahead on all CPU temperature tests when running at stock speeds. With PWM enabled, the NF-F12 was certainly the quietest of the bunch, but did suffer in terms of having the highest CPU temperatures too.  However, despite it's great performance, without PWM enabled the NF-F12 was struggling to be the quietest fan of the group tested and was overtaken by a competing model which also wasn't far off with it's CPU temperatures either.
在我的测试中，当以通常的速度运行时，NF-F12所表现出来的温度低于任何风扇的CPU温度测试。-在PWM启用后，NF-12肯定是所有风扇中最安静的，但是却要忍受CPU的高温，然而，它的很好的表现，使NF-F12成为在测试中不使用PWM时该组的最安静的风扇，这个优势将使他在这段时间成为CPU散热这个领域最具有竞争力的型号。
If I was after a high end fan, the Bentley of computer fans, the NF-F12 would certainly be a great choice as it offers many great features, a packed bundle, long lifespan and low power consumption. However, if I wanted performance and silence and wasn't worried about the specifics like lifespan, then the high $24 price tag may sway me away from the NF-F12 when some competing fans are as much as $10 less.
假如我要给电脑选择像宾利车一样高档的风扇，那么NF-F12肯定会是一个很好的选择，因为它提供了许多强大的功能，包装精致的包装，长寿命和低功耗。但是，如果我只是追求性能和安静而不用担心像寿命等等那样的细节，那么他高达24美金的售价会使我远离NF-F12,毕竟他比其它一般的风扇高出10多美金。
