Despite a large fan, it wasn't enough to cool the Alienware 15 R4! You can tell that it doesn't cool enough by the fact that the laptop fan was still running at full speed! and if you feel the sides between the laptop and the cooler, you won't feel any airflow there. Just buy a better cooling pad. Maybe with a fan speed controller (preferably automatic). This product might be good for a budget laptop, but not for gaming laptops!
