Ubuntu
忽略 lm-sensors 電壓警報是否安全?
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:

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。
