In general, computers use two fans to cool their components so that they stay at optimized functioning temperatures and do not overheat and become damaged. When these two fans are operating at full capacity, two fans is enough. In an environment filled with dust, hair, and other tiny particles, it is no surprise that computer fans are not always running at full speed. Nerds on Call can repair any broken fans that are causing your computer to overheat. Our Nerds can also recommend and install additional cooling equipment to ensure that your computer remains at a safe temperature and your hardware is not at risk of failing.
