hello i have a gx502gv which is probably the same model you have, as far as it goes for the temperatures i can tell you that it's just asus that uses a trash thermal compound, I've changed the thermal paste the other day after having the laptop for 2 years and it made a day and night difference, i used to get around 100 C on cpu and 86 on gpu playing warzone on manual with fans set to max and by also removing the back lid to get more air going now after repasting the laptop won't get past 80s on both cpu and gpu on warzone with less fan going. as far as it goes for the keyboard I've been experiencing weird bugs since this summer, some keys just are always on a different coulour, after certain updates they get back to working as normal and after some updates they just start to flash the color they want. let's just say asus didn't do his best with this laptop

it's been about 2 years since i bought my zephyrus and it's been running pretty well so far. These were the steps i took to keep my laptop running efficiently:
* cleaned the vents with compressed air. I found that dust had accumulated over time, hampering the air flow for cooling. In my opinion, the best way was removing the bottom cover of the laptop and cleaning out the dust in and around the vents, heatsink, motherboard, etc.
* replaced the thermal paste on the cpu and gpu. Since i had already removed the bottom cover of the laptop, i might as well replace the thermal paste. I have tried various thermal pastes, including the corsair xtm50. For my most recent replacement, i used thermal grizzly carbonaut. From my experience, the carbonaut offered the best cooling when running performance-intensive programs or games (during peak: Gpu stayed under 80 degrees celsius; cpu stayed under 90 degrees celsius). This procedure does require some technical skills but there are plenty of tutorials on youtube that can help you complete this successfully. If you strongly feel that you might end up screwing up the laptop, i would find someone/store that can perform this procedure. If you're planning to scrap the laptop, i think this would be the perfect time to use it as a 'guinea pig' and practice. You mentioned that you weren't a computer guru but i think that you'll be amazed regarding what you can possibly achieve!
* reinstalled the graphics card driver using the clean method. Download the latest graphics card driver and use nvslimmer to trim/remove optional files within the driver. I don't need the extra features, such as geforce experience and shadowplay. Therefore, i would remove them to prevent them from being installed on my laptop. This would also remove some unnecessary background processes/services from running, potentially offering a bit more gain in performance. You can find more info on nvslimmer here: https://forums.guru3d.com/threads/nvslimmer-nvidia-driver-slimming-utility.423072/
use display driver uninstaller (ddu) to completely remove the old graphics card driver and associated files, reboot the laptop, and then install the latest graphics card driver. You can find more info on ddu here: https://forums.guru3d.com/threads/display-driver-uninstaller-thread.379506/
you can skip the part regarding nvslimmer if you feel uncomfortable using it. I would recommend using ddu for graphics card driver reinstallation, at the very least.
* use autoruns for windows to prevent unnecessary programs from starting up with windows. This would reduce the number of processes running in the background. You can download it here: https://docs.microsoft.com/en-us/sysinternals/downloads/autoruns#download
when i felt that my laptop was still not running like it did when i first bought it, i would reinstall the operating system. I would flash the bios with the latest version (not necessary but it gives me piece of mind). The bios wipe the ssd and do a clean install of windows. Make sure no external drives are connected to the laptop while reinstalling the os. This would be my last resort if the aforementioned steps did not address any performance issues.
Hope this helps!
