MX150 & 8250u throttling

Hi! This problem was from the start. I have A517-51G-53KU. When GPU reach 67 °C, CPU drop its frequency from 2.7-3.4 GHz to base 1.6 GHz. Thats not a problem for Steam games, but its very important for video game emulators. So I search for hardware solution for this problem and what I did:

1. blackened the heat pipe,

2. used a good thermal grease for CPU & GPU,

3. cleaned the cooler from dust,

4. removed the 1mm gap between the fan and the radiator,

5. strengthened the video card clamp to the heat pipe, because it was bad.

But even after all this and the installation CPU to 2.8 GHz with an undervolt of -110mV, the video card still periodically reaches 67 degrees. How to remove this limit of 67 °C or manually limit GPU TDP for prevent it to reach 67 °C, nvidia-smi did not do that (Pwr:Usage/Cap N/A)?

Maybe use a laptop cooler like the one in this video? https://youtu.be/rzV21tUjOI0

Vacuum cooler can damage the laptop cooler. And its a new source of noise. I would be glad if there was a software solution in the form of manual control of the fan rotation speed or a more aggressive characteristic of the rotational speed or the complete shutdown of this limit on the temperature in updating the BIOS. And its sad that notebook BIOSes is VERY limited in configurable options. And no any variants like coreboot.

It's difficult to cool highly stressed I7's in desktops and probably near impossible in laptops. Perhaps removing the bottom cover and getting a cooling pad for it would work. The dinky little fan inside the laptop isn't going to cool anything no matter what its speed.

CPU 15W TDP, GPU 25W TDP / Total only 40W and 1 fan is enough for such systems. Gaming laptops with 2 fans can dissipate up to 140-200W. Also at 15W CPU itself temperature 62 °C, GPU 69 °C. So I think it can stabilize temperature at 85-90 °C with both CPU and GPU full load.

And I thought it was an official forum and Acer specialists can provide a special BIOS version for tests.

Or help create a profile for nbfc, because I'm trying to understand what values need to be changed in EC tool (RWEverything) to switch the fan from auto to manual mode and full speed mode. EC chip is ENE KB9022Q D.
