XU4 appears to be running hotter

Unread post by pdobrien3 » Thu Aug 22, 2019 1:50 am

Hello all,

I use an ssh command line to log into my odroid from home automation software every 5 minutes. The command line checks the CPU Temp on the ODroid and sends me a text if the temps are over 120 degrees Fahrenheit. Prior to last weekends updates, it rarely went over 120. Now I am consistently getting text stating the CPU temp is 150-160 degrees. My research shows that the temps may not be correct although I have never been logged in at the exact time the command line does the check. Usually several minutes later. Pretty sure the last update, this past Friday, included a kernel update but I am not experienced enough to know for sure. Was there something recently that is causing higher temps?

Thanks

It looks normal.
My XU4 CPU temperature is around 50°C in idle state. Ambient temperature is 24°C.

Code: Select all

odroid@odroid:~$ cat /sys/class/thermal/thermal_zone*/temp

My scaling is set to performance. Maybe that is it
