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

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?
答案1
限制配置不正确,它们可能是默认值或来自其他主板。例如:
+3.3V: +3.38 V (min = +0.82 V, max = +0.59 V)
对于 3.3V 电源来说,这看起来是合理的,但限制完全超出范围,最大值低于最小值!
temp2 看起来有点令人担忧,但这也可能是一个配置错误的传感器。
答案2
由于需要将比例因子应用于内部传感器的有限范围,因此驱动器很少能够正确报告电压。
请参阅此页面以获取有关如何修复特定系统设置的缩放因子的说明和教程:

一旦您知道哪些传感器报告了哪些电压,并且数字的标度正确,您就可以适当地设置最大值和最小值。上面的页面给出了一个示例。
答案3
在大多数情况下,电压通常应为 5%,并且不应偏离超过 10%。请参阅设备规格以获取确切数字。仅当您有良好的备份并且可以承受停机时间时,才忽略电压容差错误。
