Question Laptop CPU running super hot

[okayw3]

I've had an HP ENVY Laptop 16-h0xxx (i7-12700h, rtx3060 ver) for about 2.5 years now and just over a year ago I stopped being able to use it for anything intense due the CPU overheating. Even when idle the CPU might run at 60/70°C. When trying to do anything more demanding like running a game it'll run up to 100°C, then the clock speed will drop to about 400mhz causing the laptop to run extremely slowly.

I've tried a few things to fix this to no avail:
Cleaning the fans and redoing the thermal paste
Updating to the latest drivers, windows updates and BIOS
Factory resetting the machine wiping everything in case I downloaded any malware

Right now I've been using the laptop for the past year by installing throttlestop, disabling turbo and also setting my maximum processor state to 15% both plugged in and on battery. This has allowed me to keep the temperatures at around 60°C while I browse the internet and use apps like word and excel. But of course anytime I try to actually run something like steam the temp and fans kick up instantly.

Is there anything else I can try or is it likely to be a issue with the hardware itself?
Thanks

Welcome to the forums, newcomer!

Cleaning the fans and redoing the thermal paste
What is the make and model of your thermal paste?

Have you tried undervolting the GPU? As for the temps, those are temps that Intel and your laptop maker says are within limits.

Factory resetting the machine wiping everything in case I downloaded any malware
Resetting the OS doesn't do much, would've advised on a reinstall. Since I don't see it mentioned in your thread's body, try reinstalling your OS in offline mode(after recreating your bootable USB installer. Manually install all relevant drivers for your laptop in an elevate command, i.e, Right click installer>Run as Administrator while in offline mode.

Hi! thanks for your reply
I don't remember the exact model of thermal paste except that it was artic.
I've read that the H series CPUs are locked from undervolting so I haven't tried that. The CPU does sometimes run above 100, it's just that the clock speed will drop before it reaches that point. The highest I remember seeing it was 112 I believe and the chassis gets hot enough to burn you. I also haven't tried to undervolting the GPU since I never thought that it was related to the problem.

I'll repaste it again since it's been over a year since I last it did and I'll also try undervolting the GPU and if neither of those work then I'll look to reinstall the OS. I'll give an update once I try these out.

Many thanks

Quick edit: I was trying to run msi afterburner and the CPU was running at 90+°C and then it bluescreened.
