Gamersim17's laptop was "getting intensely hot." He turned to the Laptops forum for advice.
A hot computer is a bad computer. Excess heat can cause malfunctions and crashes, and permanently damage your hardware. And although laptops generally put out less heat than desktops (energy efficiency is a higher design priority), they have their own unique problems. They're rarely as well ventilated as a desktop, and much more difficult to clean.
Keeping a laptop cool is all about ventilation. If the hot air can't escape, you're going to have a problem.
