ThinkPad

I have a Thinkpad L440 that I use as a daily driver. I was looking for a laptop fan cooler, but I don't know if a fan base that just pours air from below is the most ideal, considering that the hot air comes out of the fan from the left side.

Is there some fan that might attach to the side and helps put cool air in the vent? Does that exist? Does that make sense?

Anyway, If what I say is nonsense, what fan cooler do you recommend for using with my laptop?

It will help a lot of considering that gets a bit hot while gaming, so I play for about one hour or 2, unless the game is pretty low weight like Half Life.
