忽略 lm-sensors 电压警报是否安全？

Question

我正在构建一个小型 NAS 服务器，主板是Intel D2700MUD（无风扇），PSU 是“Ace Outburst 480W”。安装 Ubuntu Server 后，我安装了 lm-sensors。输出：

coretemp-isa-0000
Adapter: ISA adapter
Core 0:       +38.0 C  (high = +80.0 C, crit = +100.0 C)
Core 1:       +33.0 C  (high = +80.0 C, crit = +100.0 C)

AVCC:         +3.38 V  (min =  +2.78 V, max =  +0.64 V)  ALARM
+3.3V:        +3.38 V  (min =  +0.82 V, max =  +0.59 V)  ALARM

fan3:           0 RPM  (min =  234 RPM, div = 128)  ALARM

fan5:           0 RPM  (min = 5273 RPM, div = 128)  ALARM
temp1:        +44.0 C  (high = +35.0 C, hyst = +32.0 C)  ALARM  sensor = diode
temp2:       +110.5 C  (high = +80.0 C, hyst = +75.0 C)  ALARM  sensor = diode
temp3:        +30.5 C  (high = +80.0 C, hyst = +75.0 C)  sensor = diode
cpu0_vid:    +2.050 V

我是否需要担心 in4,in5,in6.. 或 temp1/temp2 上的电压警报？

Answer 1

限制配置不正确，它们可能是默认值或来自其他板。例如：

+3.3V: +3.38 V (min = +0.82 V, max = +0.59 V)

对于 3.3V 电源来说，这看起来很合理，但完全超出了限制，而且最大值低于最小值！

temp2 看起来有点令人担忧，但这也可能是传感器配置错误。
