Good afternoon everyone. Maybe everyone faced a similar problem?

Lenovo ideaPad s340

It makes noise during operation, the cooler runs at high speeds.
It does not heat up, but it seems that on the contrary it actively cools the computer, not even under load.
Sometimes it can be so noisy at night if it is not turned off. That is, it turns on enhanced cooling by itself, even when working even in text editors such as Word.
I can not understand. what is the reason.
Thank you.

I met this at HP, where the heat pipe + cooler were not equivalent to iron. That is, they work out their own, remove heat, but with what forces.
For your case - open the case, blow through the cooler (possibly clogged with dust, drop oil on the twisting mechanism, usually dripping on the top of the cooler under a special label). This is the iron version.
Software - check if something is loading, some kind of voracious process.
