Dell Latitude 5411 High idle frequency

Hi! I have Dell Latitude 5411 i7-10850H I'm laptop getting hot. I want to describe symptoms depends on BIOS (or either on Power manager software too)
1.3.1:
- Constant fan noise even on low temperatures
- CPU Frequency Stuck on 0.78GHz (0.8GHz) after changing thermal management to Cool or Quite

1.4.3 (Currently installed):
- Fan Speed was resolved
- Now even on ilde (4%-5%) CPU load. CPU is on 2.3 - 2.5GHz with temperatures about 55-60C

Thermal management plan is Optimized.
Windows power plan is Balanced
Windows Power mode: Better battery.
Turbo Boost Disabled (if enable CPU became hotter and louder)
SpeedStep enabled in BIOS

I understand that 10850H is 45W CPU and it could be hot. Okay, but i'm ready it to be hot on load.
With this issue, it could live on battery only 3-4 hours
Why CPU just cant work at 0.8Ghz at idle and save power?

here Graps after clean reboot. No saftware launched, but ITU and Task Manager. On grpaph you cold see 1.45 min freq and 2.45 max freq. At Absolutely idle. System was about 10 minutes at idle before i launched ITU to be sure than all startup tasks are done.
So at absolute idle frequency jumps between 1.45 - 2.00 GHz Fan never shut up.
I previosly own Presicion 7510. I realize that it has more powerful cooling system, but 5411 i cant leave powered on at night, because it is noisy.

Another curious thing, that at settings mentioned above 2,58 is the max frequency CPU could reach.
I switched Windows power mode to Best performance and maz cpu freq. rised to 2.68 and stucked on it

In task manager what is the CPU speed being used? Also, what

temp reading do you get from EPSA Diags?  Please post  task manager image from performance http://del.ly/6607HF4Dz run the Support Assist diags follow the information and Link here.
