Cannon Lake microprocessor overheats on Ubuntu 20.04

My Laptop (Alienware m15 - 2018) microprocessor (Cannon Lake) is overheating on Ubuntu 20.04 (without running any app) unlike Microsoft windows 10, can you please tell me how can I solve this problem?

I'm using the "Temperature without third-party apps" approach from this answer as follows:

paste <(cat /sys/class/thermal/thermal_zone*/type) <(cat /sys/class/thermal/thermal_zone*/temp) | column -s $'\t' -t | sed 's/\(.\)..$/.\1°C/'

acpitz           60.0°C
iwlwifi_1        59.0°C
x86_pkg_temp     59.0°C
acpitz           27.8°C
INT3400 Thermal  20.0°C

SEN3             56.0°C
SEN4             66.0°C
SEN5             45.0°C
SEN1             54.0°C

Edit:

Using lscpu I get:
