The parts inside your computer generate a lot of heat as they operate. Some, especially the processor and graphics cards, produce enough that you need to take extra steps to keep them cool. Most modern PCs use powerful fans, but some enthusiasts choose to take things to the next level and install liquid cooling. The result is a system with tubes filled with a clear coolant, a radiator and water blocks (the water-cooled equivalent of heat sinks), and more fans to push the water around.
Aside from the obvious cost (the best air coolers can run $100 or more) and the fact that you’re working with water (which contains hazardous voltages and must be handled only by trained experts), a major downside of liquid cooling is maintenance. You have to regularly change the coolant, clean the tubing and replace the thermal paste on the heat sinks. And, of course, there’s the risk of leaks that can cause significant damage.
Traditional air cooling uses a series of thin metal fins that maximize exposure to cool air, which then pulls the heat away from the processor and disperses it into the atmosphere. This works well enough, but there are three drawbacks to it: It doesn’t get as cool as possible (especially with overclocked processors), the heat sinks can be big, and the fans can be loud.
