忽略 lm-sensors 電壓警報是否安全?

  • March 8, 2019

我正在建構一個小型 NAS 伺服器,主機板是Intel D2700MUD(無風扇),PSU 是“Ace Outburst 480W”。安裝 Ubuntu Server 後,我安裝了 lm-sensors。輸出:

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)

w83627dhg-isa-0290
Adapter: ISA adapter
Vcore:        +1.22 V  (min =  +0.00 V, max =  +1.74 V)
in1:          +1.02 V  (min =  +0.58 V, max =  +1.06 V)
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
in4:          +1.03 V  (min =  +1.25 V, max =  +0.42 V)  ALARM
in5:          +1.52 V  (min =  +1.78 V, max =  +0.51 V)  ALARM
in6:          +1.02 V  (min =  +0.16 V, max =  +0.10 V)  ALARM
3VSB:         +3.34 V  (min =  +1.65 V, max =  +1.15 V)  ALARM
Vbat:         +3.22 V  (min =  +2.34 V, max =  +1.02 V)  ALARM
fan1:           0 RPM  (min = 2109 RPM, div = 128)  ALARM
fan2:           0 RPM  (min =  458 RPM, div = 128)  ALARM
fan3:           0 RPM  (min =  234 RPM, div = 128)  ALARM
fan4:           0 RPM  (min =  659 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

我需要擔心 in4、in5、in6.. 或 temp1/temp2 上的電壓警報嗎?

限製配置不正確,它們可能是預設值或來自其他板。例如:

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

對於 3.3V 電源,這看起來是合理的,但極限已經完全超出,最大值低於最小值!

temp2 看起來有點令人擔憂,但這也可能是感測器配置錯誤。

驅動程序很少能正確報告電壓,因為需要將比例因子應用於內部感測器的有限範圍。

有關如何為您的特定係統設置修復比例因子的說明和教程,請參閱此頁面:

http://www.lm-sensors.org/wiki/VoltageLabelsAndScaling

一旦您知道哪些感測器報告了哪些電壓,並且數字被正確縮放,您就可以適當地設置最大值和最小值。上面的頁面給出了一個例子。
