I noticed that my CPU works louder when I am plugging my laptop in.
I am using an HWMonitor Version 1.40.0 Driver version 148 to check my status of CPU.
I am worried that my laptop can be damaged soon. HWMonitor shows or my every core there is a Value around 3600 - 3900 MHz.
When I am disconnecting my power supply from the socket HWMonitor shows 690 - 980 MHz.
It's a big difference.
Is it something wrong with my laptop, power supply or maybe there is something wrong with my an electrical installation at home?
What should I check or fix?

Since you didnt list your laptop's model, I cant say with the following with 100% certainty. However, it is very highly probable to be correct.
Your laptop is working absolutely as it should. 3.9 GHz (3900 MHz) is a typical speed for a modern CPU, including its cores. When plugged into an AC outlet, your laptop will run faster. When unplugged, laptops often slow down the CPU to last longer on batteries. The laptop can scale the CPU power up as needed as well. Naturally, at full power, the CPU generates a lot of heat and the fans run at high speed to cool it. The fans spinning is the sound you hear. Again, this is absolutely normal and safe.
However, if the machine is constantly running at 100% CPU usage, there very well may be an issue.
