If your laptop is known to overheat, then you better get a laptop cooler, before it melts down. But the problem with coolers is that every laptop gets hot in different places, and not every cooler will work for the same laptop.
The iGo Arctic Laptop Cooling Pad should do the trick. It houses a movable fan so you can make sure the right spot gets cooled, making it more effective. It is powered by a removable USB cable that can be stored inside the cooler itself when not in use, and it features an ergonomic design to make using it more pleasant. You can pre-order it now for $29.99 and it ships out on March 22.
