Do laptop cooling cushions work?

I have used 3 cooling pads so far and they help.

In general, they all reduce the inside temperature, but of course that depends on how much you want to pay for it.

If you are a player looking for a low price, I can suggest LotFancy 12R-2697-S. From my experience, this has helped keep my laptop down between 20% and 30% during game sessions.
