Please take a look at my computer's temperatures below:
coretemp-isa-0000
Adapter: ISA adapter
Package id 0: +56.0°C (high = +86.0°C, crit = +100.0°C)
Core 0: +56.0°C (high = +86.0°C, crit = +100.0°C)
Core 1: +52.0°C (high = +86.0°C, crit = +100.0°C)
dell_smm-virtual-0
Adapter: Virtual device
Processor Fan: 0 RPM
CPU: +55.0°C
Other: +47.0°C
Other: +44.0°C
GPU: +52.0°C
Are these temperatures normal?
Is the processor fan not working?
How do I control the speed of the fan processor?
sudo apt install tlp tlp-rdw && sudo tlp start
so you may have more tools to monitor your fan. Without knowing your model number (from the serial number plate/sticker, please), that's about as much as we can suggest. Please obtain that model number, then click [edit] here and add it to your question. Please do not use Add Comment; instead, please use [edit]. – K7AAY Aug 12 '19 at 22:31
