AN515-55-78XJ - fans and temperatures

Notebook: Nitro 5, GTX 3060, i7
I noticed that the fans remain on while system is idle. I checked temperatures and fan speed during browsing the internet. This what I get:


My questions are:

1. What is real CPU temperature. Is it 51 or 23 degrees?
2. If it is 23 degs. why both fans are running?
3. I didn't use GPU, why GPU fan are running?

I checked the temperature of the air blowing through the vents and it's definitely under 50 degrees!

I'm asking these questions because I buy Nitro 5 to work and for games, and I expect when system is idle notebook should remain silent. I previously have Aspire VN7-591G and when nothing happened, the fans stayed off and turned on at very low speed from time to time. Here fans are off very rarely and and after a while they turn on again.
I tried to change power plans, change NitroSense settings but it didn't do much.
Does Acer plan to change the fan settings / update NitroSense tool or do anything that will enable silent operate at no load?
This is my 3rd Acer notebook and I really don't want return it to the store!

thanks, wk

    Speed Fan is not a reliable one. You can use other software like HWMonitor. The fan is always on when the laptop is plugged in. Both fans have to run at the same time by default.
    Please remember to include @AnhEZ28 when you want to reply back to my comment so that I can check your response.
    Thank you and have a nice day!

    When laptop is plugged in and system is idle for a while, fans are off. But practically any activity raises CPU clock upto 4 GHz and temperature, making fan turn on immediately.

    It would be nice for Acer to modify the energy saving plan and set the maximum processor clock to (for example) 1GHz, which is sufficient for writing text or browsing the Internet and will probably not require active cooling.
