On a CentOS 7 system I saw "Core temperature above threshold, cpu clock throttled" messages like those below appear on the console today.
[68546.319229] CPU1: Core temperature above threshold, cpu clock throttled (total events = 189995) [68546.319240] CPU0: Core temperature above threshold, cpu clock throttled (total events = 189989) [68546.519121] CPU0: Core temperature above threshold, cpu clock throttled (total events = 192228) [68546.519131] CPU1: Core temperature above threshold, cpu clock throttled (total events = 192234)
I checked to see if the lm_sensors package was installed on
the system, so I could check fan speeds and the
central processing unit (CPU) temperature. It wasn't installed, so I
installed it from the root account with yum install lm_sensors.
