Many PC gamers rely on a high-tech gaming mouse for fast, precise aim in FPS and other games. These mice can also allow for more comfort than PC gaming controllers during extended game sessions, with less cramping in the hand and fingers, especially when paired with complementary gaming keyboards. And since a gamer mouse is, of course, a mouse, it can also perform double duty for everyday computing.
A computer’s internal components heat up whenever a lot of demand is placed on them. Despite the best efforts of manufacturers to dissipate this heat using fans and heat pipes, some areas of a laptop tend to get hotter than others. This can make gaming laptops quite uncomfortable to use (especially when placed on their user’s lap!); this high heat can also endanger a laptop’s internal electronics if the computer’s ventilation slots become obstructed (be careful not to let your computer’s ventilation system get clogged up with dust!). If you intend to place your computer on your desk and use an external mouse for gaming, its temperature will not be a major consideration.
