Question about a Bug that was rather helpful: Predator Helios Neo 18 AI (5070 Ti, Intel Ultra 9 275HX)

Hello everyone!

This might sound unusual, but when I was on Nvidia driver 577.0, I ran into a bug that actually turned out to be useful rather than annoying.

The issue was: “Unable to change display mode.”
While it caused a slight and almost unnoticeable performance drop, it dramatically lowered GPU thermals even in Turbo mode and made the fans run much quieter. It was honestly a great side effect: cooler temps, minimal noise, and only a barely perceptible FPS loss.

After updating to the latest driver, the bug is gone and I’m back to high temps and loud fans again.
So my question is:
Does anyone know what caused this “Unable to change display mode” bug originally? I know it's one of my background apps, and I know which one it is.
And is there any way to safely replicate its cooling behavior without rolling back to 577.0?
I’d really like to experiment with this again. I much preferred the lower temps and quieter fan curve, even if it meant sacrificing a few frames per second.

Thanks a lot in advance!

Hi Rebalosho,
I can recommend this Acer guide for optimizing cooling: https://community.acer.com/en/discussion/724763/ultimate-laptop-cooling-optimization-guide

Hello Puraw!
Thank you for your swift reply. I have already visited this guide and it helped me optimize my thermals. However, the topic at hand is a little different.
I would like to understand the technicalities behind the bug that allow the laptop to run at lower temps and lower fan noise.
I would like to replicate that, without the need to rollback to 577.0.
