After installing fresh Windows 1903/1909, CPU frequency is higher than expected causing excessive heat. This is when AC plugged, on battery it works better.
With 10% of utilization its frequency 3.8Ghz in balanced mode (10% gives single PredatorSense when in screen)
This is due to lack of a driver on Acer download page.
I tried a driver form Triton 900 which has 9880H and it works really well, frequency dropped from 3.8 to 3.2-3.3, in other tasks I see also proper behavior which is now more relevant to other lenovo laptop I can compare. On idle, with 0-1% CPU load frequency is 1.7Ghz so cpu temp can even go to 29C

This is Turbo Boost Driver by Intel

    What frequency range do you want to see on an i7 9th generation?

    I mean that under light load below 10% it should not race at full 4 Ghz
    I have no problem with the power when it is really needed, my cinebench r15 scores 1280 average which is very high

    belik on 1909 i know that they enable something that will make only 2 cores working while the others are kept parked/idle so stressing out 2 only and generating more heat as microsoft its ran by old men lol this its a little bit duh isnt it :p dunno if this has something to do with this or not :)
