Good additional cooling on the laptop?

Has or knows someone. Another way to better cool the laptop?

Place a piece of wood or the like at the back that extends over the entire width of the device, thus creating a little more space under the box. Otherwise it also helps (if the device has a few days under its belt) sometimes cleaning the cooling system (or having it cleaned). In my experience, all these super cool laptop coolers to put under don't really bring anything.

Okay many.

Liquid metal instead of conventional thermal paste
VRAM cooling pads.
Cooling pads (notebook pad with fan)

Those were the things that spontaneously spring to mind.

These cooling pads tend to bring less than more. And if you are not that experienced you should (not even with the help of YT) mess around with a laptop. Especially no changes to the cooling. And that there are "extensions" for the VRAM is new to me.

For example something like this: https://www.pearl.de/a-HZ2810-1143.shtml?vid=917&wa_id=40&wa_num=1105

My friend had great success with a frozen fish.
It is best to shrink it, otherwise your laptop will have an unpleasant odor after a while.
