Anyone with a computer or smartphone knows the instinctive fear of spilling something on the keyboard or screen. This concern is hardly unfounded. Water can destroy the delicate connections that are the basic part of any computer, rendering your device inoperable in a flash.

On the list of things that can damage your computer, heat is not far behind moisture. The components in a computer tend to be made of delicate silicon wafers or plastic chips; either one can be destroyed by overheating.

Computers tend to overheat from the central processing unit, or CPU, thanks to the millions of microscopic switches that comprise a computer’s RAM. The continual fluctuations in power, coupled with the natural resistance to electric current, cause some of the electricity to move through the CPU to be converted to heat.

When high load tasks would otherwise mean the CPU heating to a dangerous degree, a computer’s first fear can come to the rescue. The same conductive properties that make water so destructive to a computer also make it an excellent heat receptor. A liquid cooling array can keep a computer cool even under unusually heavy workloads.

If you are planning on any serious processing or gaming, you are probably considering a liquid cooling array as well. Here are five of the best liquid coolers to keep your computer frosty while you work.

Final Verdict

Heavy computer usage puts out a surprising amount of heat for a machine in which absolutely nothing is supposed to be burning. A liquid cooler sucks that heat away far faster than trying to blow it away with air currents.

If your computer requires additional cooling, or the unit is not lowering temperatures enough, take a look at the area around the computer. If papers or desk walls are obstructing the radiator vents, they will trap the heat inside the radiator and drastically reduce its effectiveness.

For both your own safety and that of your computer, it is worth checking closely to see if the reservoirs or piping have any leaks in them before installing the unit. Leaking coolant can instantly disable your computer and presents a serious risk of electric shock to someone touching the wet area.
