You’re computer’s processor almost always comes with a small cooler that, while working well enough that you shouldn’t need to worry about overheating, are about the weakest coolers you can buy, but is it worth buying an aftermarket cooler? The answer to that is a definite yes. Not only will you get much lower temperatures, which increases the longevity of the processor, but it’s often quiter as well, and shouldn’t run you more than $50 for a really good one.
