Water Cooled Computer: Case, CPU, PC, Power Supply

Computers are common tools that we use every day. While they will constantly be in our lives, they are not always a constant themselves. Computers will always be used for different things and will change as they get older, but one consistent characteristic of the computer is heat. As long as a computer is running, its core components are heating up. The longer it is in use, the more heat the computer will produce. This means that computers need a way to manage the heat and stay cool. Normally this is done with an air cooling system that blows out all the hot air. This standard cooling system is sufficient, but water cooling a computer can be a far more effective method.

A water cooled computer can actually work much better than the standard fan cooled one. Water cooling involves pumping cold water through tubes to the CPU block. The water passes over the hot surface of the CPU and absorbs the heat, making the CPU cooler. Once the water has passed over the CPU, it continues on to a radiator. The radiator then disperses the heat from the water, making it cold once again. Finally the water moves on to a reservoir so it can be pumped back through the system.

Water cooled computers are generally cooler because the system takes heat away from the source and manages that heat elsewhere. A standard air cooling system will simply blow heat away. This means that if it doesn't work fast enough, too much heat can still build up inside the computer. Also, depending on how and where the computer is set up, a fan may just be blowing the hot air around the outside of the computer, which isn't very efficient in keeping it cool.

Overclocking is a big concern which can be handled better by a water cooled CPU. Heat is what will make a system unstable and stability is key when overclocking. In order to overclock a computer you must increase the voltage to the CPU, which gives it more power and keeps it stable while you make it work harder. Increased voltage also means an increased amount of heat coming off the CPU. An air cooled computer may not be able to handle this kind of heat while a water cooled computer will manage the heat better.

A water cooled power supply is a good companion to a water cooled PC. The PSU works by converting the alternating current (AC) from the wall socket to the direct current (DC) that is used by the computer. The power supply can also heat up, just like the CPU, and typically includes an air cooling system. Well if you have a water cooled computer, why not water cool the power supply as well? Just as water cooling is better for the CPU, it is also a better system for the PSU.

An overheated computer is basically a large paperweight, so consider taking the better route to cooling, with a water cooled computer. This can be especially important if the computer is used often or for work purposes, as it can be very frustrating to have your computer stop working in the middle of an important project.
