In computers, water cooling is a method used to lower the temperatures of computer processors, and sometimes other components such as graphics cards, using water rather than air as the cooling medium.
Processor speeds have increased dramatically in recent years. As a result, the heat given off by processors has also increased, as has the noise associated with equipment, such as fans, used to keep them running at a safe temperature. Because water can conduct heat about 30 times faster than air can, a water cooling system allows the processor to run at higher speeds while drastically reducing system noise.
Benefits of Water cooling in Computers
1. Good for warmer climates
If you live in a location with high ambient temperatures, adding a hardware-heavy gaming PC into the mix can be a recipe for overheating and loud fans.
Because the water system works on an ongoing basis, those working in naturally warmer spaces don’t have to compromise on performance.
2. Cools off high-performance GPUs
These days, a high-end GPU can generate two or three times the amount of heat of a CPU. As a result, you’re bound to notice a major increase in fan noise when you’re in the midst of an extended gaming session.
Water cooling presents an attractive solution because, again, it cuts down on noise and offers an efficient means of cooling things down.
3. Sustains cool temperatures over time
From smartphones to laptops, electronic devices just have a tendency to get hot. You know this if you’ve experienced the sensation of a burning lap while you’re simply checking emails.
An air-cooled PC uses the ambient air around it to push hot air out of the computer system, which works to cool things down even when your computer isn’t working all that hard.
Fans will respond after there’s an increase in heat. So if you’re streaming or gaming, the fan steps in to cool the components by blowing away any excess heat. Liquid cooling, on the other hand, keeps your PC running at a lower temperature all the time.
4. Higher level of efficiency
While the idea of placing liquid anywhere near your computer sounds a bit counterproductive at first, water cooling is actually much more efficient than air.
Water transfers heat more effectively because of its high thermal conductivity, which means the water works to diffuse heat from various components in your gaming computer build.
Essentially, you’re comparing a central air system to a box fan. Going the liquid route means your computer is operating at a consistently cool temperature, while a fan typically only kicks into gear as the computer overheats.
5. Less noise
A water cooling kit will reduce the need to use more than one fan in your PC case. The self-contained loop of water cools quietly, so you don’t have to worry about loud fans breaking your focus while fighting that last big boss in your favorite game.
Most liquid-cooled units do include one fan in the build, though. The liquid system takes on the bulk of the work, while the fan circulates the air.
6. Improves overclocking potential
Overclocking is the process of setting your CPU multiplier at a higher frequency, which speeds up your processor and other components. However, this process can damage your computer if you’re not careful, because it increases the heat generated by your system.
Liquid cooling keeps your overclocked hardware cooler, so you won’t crash your computer or damage your hardware because of overheating.
7. Liquid cooling takes up less space than fans
Water definitely wins when it comes to real estate. Fans take up far more space than the thin tubes of water in your average liquid cooling kit.
If you’re building a gaming computer or running demanding programs, this type of cooling system may be ideal for you. It becomes clear that liquid is the more efficient, quiet solution that keeps your computer from overheating in spite of overclocking or other sources of computing stress.
