Unverified风力大小与噪音、重量、续航三者互相制约：大风力往往意味着更重电机、更高噪音或更短续航，通勤日常无叶款开中档即够用，无需盲目追求大风量84% similarUnverified风力越强的风扇电机功率越大、噪音越高、体积越重，夹持稳定性也越差；主驾降温建议中小风力低噪款，需要大范围快速降温则牺牲噪音换风量83% similarUnverified通风系统越复杂（多进气口+扰流尾翼）散热越好但抗风噪越差、高速时呼啸声越明显，城市低速可选高通风，长途高速需在通风与静音间平衡82% similarUnverified风量与噪音不可兼得：同尺寸风扇提升转速可增大风量但噪音呈非线性上升，日常使用应设置温度曲线让风扇在低负载时低转速，仅高温时提速80% similarUnverified静压越高送风越远但风机功率大、噪音随之上升；家用普通户型选可调静压机型（多档位）比一味追高静压更明智，安装后按实际管长调档可兼顾风量与静音79% similar
