Think about it. Cars and Laptops are similar in the fact that they both generate lots of HEAT. With the automobile you want the engine to be warm, but not overly hot. However, in the case of the laptop computer, you strictly want the temperature to be as low as possible. In other words, you never want to "warm up" a laptop the way you would warm up a car. Computers actually run faster at lower temperatures. The main purpose of a laptop cooler is to protect you and the delicate components of your laptop from the dangers of heat, but a side benefit is that it could theoretically give you a tiny boost of computer performance.
