If you're using Asus Rog G7XX series the coolers are useless.
Why?
Because the intake is beneath your monitor and I do not think there are coolers that cool like that.
Coolers are meant for cheap laptops where air intake is poor.
Gaming laptops don't need cooling as they have their own cooling build inside of them.
