Acer Swift SF314-59 running hot after BIOS update to V1.07

Hi, I was very pleasured with my new Acer Swift SF314-59 i5-1135G7. The notebook was able to keep a perfectly constant TDP of 28 Watt while running the Cinebench R20 benchmark, from the beginning to the end with an result of 2115. The fan spun up high and there was no thermal throttling. Now with BIOS 1.07 my Acer runs much hotter in general. The fan barely spins up. And the hardware runs much hotter than it should be. I can't imagine, that this will be beneficial for the notebooks life span. I run the Cinebench R20 again and realized, that now the fan don't spin that high any more. The notebook now runs very hot and there is thermal throttling so that the TDP drops to 24-25 Watts. Now j get only a result of 1951 in Cinebench. Also on desktop/web browser, the Notebook runs hotter, because the fan spins to low or is completely off. So how can i get the previous behavior, where my fan spun up more frequently and higher, and my hardware was barely warm?

    Hmm, the TDP 17Watt/65°C after 20 seconds full load problem is a specific one with Cinebench R20.
    I run also Prime95, Heaven Benchmarks, FurMark and my Acer can still maintain a high TDP around 28Watt 85
    °C for a long time.
    Sorry for the 
    confusion! Love my Acer again :)

    I reinstalled Windows back to version 10.0.19042.631 (I have had the newest Windows running before)
    After some initial reboots (Intel and Realtek drivers installed automatically, but older ones) I got back my constant TDP of 28Watt and the Cinebench score is back to 2105 after three runs.
    So it wasn't the BIOS update. But something is coming with the newer version of Windows/Intel drivers/microcode updates that changes the TDP/Max temperature behavior of the Tiger Lake platform :/

    The fan was also able to manage the max temperature of 85°C again on 28Watt TDP.
    I gonna check the behavior again, when Windows/Intel is going to update itself to the newest version in few days.

    Just got the Windows update to 10.0.19042.928 (from 10.0.19042.631)
    And I cant believe it!
    Under the new version of Windows, when running Cinebench R20, I get a drop from 2100 to only 1700 poins!
    Before the update, I got a constnt TDP of 28Watt and 85
    °C.
    Now with the newer Windows, when running Cinebench R20, it starts with TDP 39Watt (!!!) for the first 15-30 seconds by 92
    °C, slowly drooping to 17Watt and 65°C and staying there to the end of the Cinebench run, resulting in a 400 points drop from 2100 to 1700!
    Acer what are you doing?
    You are castrating my Notebook from a brilliant constant TDP 28Watt/85°C to a mediocre TDP17Watt/65°C after 20 seconds full load???
    How can I get back my constant TDP 28Watt/85°C ???
