It is not very often, actually rare, that an unmodified computer from the factory will overheat. Even when you add a graphics card, you shouldn't have any problems. What can kill a computer, and requires extra cooling, is "overclocking". Basically making a processor work harder than it was designed for. If done correctly, it is a cheap way to get a better faster computer, but if done improperly you will get a cooked computer.
Having the computer fan speeding up is not necessarily a sign of a problem, it is just doing its' job, cooling the computer.
