前言

16XG万兆交换机 噪音太大了。所以我安装了Noctua NF-A4x20 FLX风扇。

修改后的风扇在外面看起来是一样的。

原装的风扇： SUNON MC30151V2-0000-G99

是SUNON MC30151V2-0000-G99。该风扇的规格是4.8 CFM @ 7000RPM，27 dbA (8.2 m³/h)，风扇是12V的电压。

上面的改造方案 来自最早的方案，现在我切换到 40 毫米风扇时，我将它们取下。

由于UniFi Switch 16 XG配备 30 毫米风扇，因此需要一个自己打印一个适配器。

40mm 替换风扇

我选择了Noctua NF-A4x20 FLX风扇。规格是（9.4 m³/h，14.9 dBA）共有两条减速线：

LNA NA-RC10（8.3 m³/h，12.2 dbA）和 ULNA NA-RC12（6.9 m³/h，8.5 dbA）

使用减速线，会降低风速，所以自己慎重选择使用！

使用风扇自带的螺丝固定在适配器上。

目前测试没有安装低噪声适配器，如果以后噪音大，估计会加上减速线。
