Hello, I installed Fedora 42 KDE version, My laptop fan is running non-stop. 42 version is like Windows 11, CPU is working very hard and the temperature is increasing. The fan is running constantly. Will there be an update for this?

In a terminal run the top program so that you can see which program is using the CPU time.

top -n 1 -b | head -n 20

Then post the output as pre-formatted text for us to review for you.
Pre-formatted text using the</> button or you type it like this:

The issue seems to be AnyDesk, but the CPU is running at 10% - 15%.

Anydesk is third party software not packaged by Fedora I think.
You will need to ask them why the app is using 90% of a CPU core all the time.

I assume if you stop anydesk your system CPU goes to idle as you expected?

Your CPU seems to be a 4 core / 8 thread model. So 10-15% usage (in terms of total CPU capacity) is about what you’d expect from a process that has 1 thread constantly active.

For your interest. Thank you…
