Is that normal?
No, that's very high.
Will CPU hardware itself control the frequency to fit the temperature?
Yes, but you don't want that. Going into thermal throttling means you're getting less ...

CPU temperature often reaches 100°C
Same sensors command should tell that 100°C is the high temperature threshold eg:
Core 0: +37.0°C (high = +100.0°C, crit = +100.0°C)
Once it reaches the high threshold, in addition to active ...

Why can't tree fully list /sys/class/hwmon? And how could I do that?
tree behaves that way because it doesn’t dereference symlinks by default. The -l option will change that:
tree -l /sys/class/hwmon/
but you’ll have fun making sense of all the output.
