Any additional cooling the best laptop cooling pad can deliver will help in the battle against throttling. It could also potentially prolong the longevity of your laptop. That CPU and GPU will last longer if they aren’t being constantly run at overly hot temperatures.
So spending a little money on some extra cooling might save you a lot of heartache by avoiding the danger of your notebook giving up the ghost early. The best laptop cooling pad can also provide a convenient place to situate your laptop on those occasions when you’re actually using it in your lap, preventing a warmer notebook from being unpleasantly hot against your legs.
Note that the mileage you get from any cooling pad may vary in terms of the cooling vents present on the bottom of your notebook, and their respective position compared to the location of the fans in the pad. As common sense would dictate, a decent amount of vents on the underside of your laptop is a good thing here – and in general – and preferably these will be (roughly) lined up with the pad’s fans.
Although some laptop cooling pads run with one big fan – or multiple smaller ones – that’ll hit pretty much everything, and there are even modular pads where the fans can be repositioned.
Even unfortunate notebooks with no vents on the bottom can benefit somewhat from having the underside of the chassis cooled as a little bit of help in terms of temperature management.
At any rate, while your mileage may vary somewhat given your exact model of laptop, you’ll likely find some benefit from a cooling pad – and perhaps a considerable one, providing, of course, that you choose the one of the best models around.
