AMD FX-6300 CPU温度异常过高引发系统故障求助

各位大佬好，我最近碰到个头疼的问题：我的AMD FX-6300 CPU对应的温度传感器（k10temp-pci-00c3）显示温度离谱的高，哪怕只是打开个浏览器或者播放视频都会触发，已经导致系统出现故障了。之前系统一直正常运行，这问题是最近才冒出来的。

下面是我用传感器工具抓取的详细数据：

k10temp-pci-00c3
Adapter: PCI adapter
temp1:       +176.6°C  (high = +70.0°C)
(crit = +85.0°C, hyst = +83.0°C)

in2:           0.00 V
in3:           0.00 V
in4:           0.00 V
in5:         864.00 mV
in6:           1.10 V

temp1:        +39.0°C  (high = +255.0°C, hyst = +251.0°C)  ALARM (CRIT)
(crit = +255.0°C, hyst = +251.0°C)  sensor = transistor
temp2:        +76.0°C  (high = +255.0°C, hyst = +247.0°C)  ALARM
(crit = +80.0°C, hyst = +72.0°C)  sensor = thermistor
temp3:        +37.0°C  (high = +255.0°C, hyst = +253.0°C)  ALARM (CRIT)
(crit = +255.0°C, hyst = +253.0°C)  sensor = transistor

有没有大佬能帮忙分析下？这到底是传感器误报还是真的温度炸了？该怎么排查解决这个问题呢？
