High Temperature on Ubuntu Server 18.04 (ASUS Chromebox)

I installed Ubuntu Server 18.04 on my ASUS Chromebox2. When issuing the command cat /sys/class/thermal/thermal_zone*/temp it returns the following:

43000
96500
42000

The numbers shown, indicate the temperature in millidegrees Celsius (m°C). So 96.5°C celsius is way to high. Since this is a newly bought Chromebox, is it possible that I misinterpreted the numbers or do I need to replace the hardware right after buying it?

EDIT: Running lm-senors after some time of letting the Chromebox run, reports the following:
