What is this ? I———————-I

This a scheme of a simple system that can help decrease the heat of your laptop.
with these two feet you will increase the air intake of your laptop and then help to consequently decrease the heat of your laptop.
Very simple and easy to built, I make it with wood 2 screws and it’s done. I use it before with acer aspire 3002, and it was really helpful but know with my aspire 5102wlmi I do not have this heat problem then I’m not using it.
Hope that can help you.
