Sure! This old one from GamersNexus runs through some pretty good detail and even arrives at the same "20C temperature reduction" conclusion I experienced. https://www.youtube.com/watch?v=d42PSM0CN8g Best will be to youtube for your specific model laptop to see if there are any connectors to be particularly careful of when opening. The hardest part will be finding all of the screws to remove the bottom of the laptop. In addition to the x10 around the perimeter, my Dell has a little flap which hides two easy-to-miss screws.

And bonus, here is a bit of a theatrical conclusion to changing thermal pads on an Nvidia GPU https://youtu.be/-kPUq-q8tT8?t=410 (observed memory temperatures dropped from 110C to 70C, 40C reduction, and overall GPU performance doubled)
