电扇的英文怎么读

前言
德商德静界（be quiet!）是一家专注于打造静音产品的高端品牌，而且静音的卖点是基于保证性能的情况下实现的，试问一台散热性能不错、运行安静的电脑主机谁又不爱呢？最近德商德静界为PURE WINGS系列更新了第三代风扇产品，相比上一代优化了框架、风扇叶片、叶片角度、马达等方面，又能保持原有的高性价比。
PURE WINGS 3系列提供了140mm和120mm两种常规尺寸，并各自划分普通版、PWM版以及PWM高速版，本次开箱的是PURE WINGS 3 120mm PWM 高速版，并为大家带来散热器替换风扇的对比性能测试。
产品开箱
PURE WINGS 3系列包装延续了德商德静界（be quiet!）一贯的纯黑低调主题，右上方有其be quiet!的英文，其中“quiet!”部分用经典橙色凸显，正面展示了风扇渲染图和具体型号，具体参数信息留在了包装背面部分。
包装背面提供了11种语言说明和关于德商德静界（be quiet!）品牌的详细介绍，下方是PURE WINGS 3 120mm PWM 高速版详细规格和参数。
PURE WINGS 3 120mm PWM 高速版整体外观为纯黑，采用标准120mmX120mmX25mm规格设计，相比普通版和PWM扇叶从7片增加到9片，转速更高达到2100 RPM，并且其风量、风压分别可以达到59.6 CFM、2.41mm H2O最大值。
PURE WINGS 3 120mm PWM 高速版延续了德商德静界（be quiet!）代表性的水波纹扇叶，在扇叶上有多条规则凹槽，能显著增强气流，促使噪声的湍流降至最小，最大噪声值仅30.9 dBA。风扇框架也采用全新模具设计，可减少漏风现象，配合特殊的叶片和叶片角度能获得更大风压，用在冷排和散热器上尤其合适。
PURE WINGS 3 120mm PWM 高速版扇框一侧上有be quiet!的黑印LOGO，显得低调。
扇框另一侧则有两个箭头，一个箭头代表着扇叶旋转的方向，另一个箭头则是指气流的方向。
PURE WINGS 3 120mm PWM 高速版延续了上一代的来福轴承技术，技术成熟平均寿命可达到80000小时。它还内置了闭环马达，马达会持续监控当前风扇转速，当遇到有阻力情况风扇转速变慢时，风扇会自动拉升转速到所需目标值，充分保证性能完美发挥。
PURE WINGS 3 120mm PWM 高速版采用标准4pin的PWM插头，线缆为扁平化设计，线缆长度为460mm，足够各种安装环境下使用。
本次搭配测试的散热器是德商德静界（be quiet!）的SHADOW ROCK 3，它是一款采用五根6mm镀镍热管+非对称大面积鳍片结构的单塔风冷，官方宣称能提供190W TDP散热性能，顶部还采用了双色拉丝处理铝制顶盖，配备一枚SHADOW WINGS 120mm PWM 高速版（1600RPM）风扇。
本次测试将通过PURE WINGS 3 120mm PWM 高速版、SHADOW WINGS 120mm PWM 高速版以及振华MEGACOOL 120mm搭配SHADOW ROCK 3本体进行，前两者分为主板PWM控制转速和最高转速两种情况对比，而振华MEGACOOL 120mm属于工业级风扇，厚度也达到30mm，因此仅设定为LOW模式（2000RPM）进行测试。
测试CPU为Intel Core i5-13490F，搭配主板来自微星的MPG Z790 EDGE TI MAX WIFI（中文简称Z790刀锋TI MAX），它采用了16（90A）+1+1超豪华供电体系，拥有M.2 GEN 5插槽X1和M.2 GEN 4插槽X4，并全部覆盖冰霜铠甲，内存部分支持超频至DDR5-7800+MHz，是一款实力超群的中高端Z790主板，下面所有测试都是AIDA64最新版本单选FPU烤机项目进行。
性能对比测试
PURE WINGS 3 120mm PWM 高速版主板设置最高转速，实际显示为2097 RPM，CPU Package最高60
PURE WINGS 3 120mm PWM 高速版最高转速时噪声值为51.8 dBA
PURE WINGS 3 120mm PWM 高速版主板设置PWM控制转速，实际最高显示为1425 RPM，CPU Package最高63
PURE WINGS 3 120mm PWM 高速版主板设置PWM控制转速时噪声值为44.3 dBA
SHADOW WINGS 120mm PWM 高速版主板设置最高转速，实际显示为1711 RPM，CPU Package最高63
SHADOW WINGS 120mm PWM 高速版主板设置最高转速时噪声值为50.1 dBA
SHADOW WINGS 120mm PWM 高速版主板设置PWM控制转速，实际显示为1290 RPM，CPU Package最高66
SHADOW WINGS 120mm PWM 高速版主板设置PWM控制转速时噪声值为43.6 dBA
振华MEGACOOL 120mm（LOW模式）主板设置最高转速，实际显示为1976 RPM，CPU Package最高59
振华MEGACOOL 120mm（LOW模式）主板设置最高转速时噪声值为55.7 dBA
以上是所有测试成绩汇总图表
结语
从以上测试结果来看，PURE WINGS 3 120mm PWM 高速版在满载高转、由主板PWM信号控制两种情况下，噪声和散热性能表现都是很出色的，在满载状态时，仅和振华MEGACOOL 120mm这种工业级风扇仅相差1，噪声表现却低很多，而且其售价几乎是PURE WINGS 3 120mm PWM 高速版的两倍了。
而在主板PWM信号控制时，能把Intel Core i5-13490F压制在63，此时和SHADOW WINGS 120mm PWM 高速版满载温度表现是一样的，但PURE WINGS 3对比下来所需转速是更低，噪声也就有更好的表现。
因此， 德商德静界（be quiet!）PURE WINGS 3 120mm PWM 高速版这款风扇，用在主流散热器、冷排替换风扇方案上就特别合适，目前其售价为119元，性价比高，适合追求静音和性能均衡的玩家。
