I have experienced thermal throttling on my i5 processor laptop and as far as I am concerned, the solutions to this problem is more or less the same across all types of laptops and platforms. There are a few things you could do to prevent such an incident. I am happy to share it with you now -
Check the condition of the thermal paste. A new thermal paste can be applied for better results.
Make sure to set the power consumption mode on ‘Best performance’.
Try to disable throttling via Registry. I can help you more on this if you want. Do share your thoughts and I’d be happy to help you.
