LiquidCooling

 

A computer's many componenents produce large amounts of heat while it is running, so the heat must be cooled in order to keep these components at a safe level. Overheated parts generally have a shorter maximum life-span and may give problems resulting in system freezes or crashes. A computer's microchips are full of electric transistors, which are basically electrical switches that are either on or off. As transistors change their states between on and off, electricity moves around in the microchip. The more transistors a chip contains and the faster they change states, the hotter the chip gets. There are three different types of liquid based cooling. They are water, refrigerant and dialectic fluid.

 

 

Liquid cooling is essentially a radiator for the CPU inside of the computer. A liquid cooling system circulates a liquid through a heat sink attached to the processor inside of the computer. As the liquid passes through the heat sink, heat is transferred from the hot processor to the cooler liquid. The hot liquid then moves out to a radiator at the back of the case and transfers the heat to the air outside of the case. The cooled liquid then travels back through the system to the CPU to continue the process.

 

Advantages

Liquid cooling is a much more efficient system at drawing heat away from the processor and outside of the system. This allows for higher clock speeds in the processor as the temperatures of the CPU core are still within the manufacturer's specifications. This is the main reason why extreme overclockers like to favor the use of liquid cooling solutions for their processors. It is possible to almost double the processor speed by using very complex liquid cooling solutions. The other benefit of liquid cooling is the reduction of noise within the computer. Most current heat sink and fan combinations tend to generate a lot of noise for the fans that need to circulate air over the CPU and through the system.

 

Disadvantages

Unfortunately there are a large number of disadvantages to liquid cooling in computer systems these days. Some disadvantages are size and technical skills required to install a kit. Liquid cooling kits require a large amount of space within the computer case to work effectively. In order for the system to work properly, there must be space for items such as the impeller, the fluid reservoir, the tubing, fan and power supplies. This needs a larger desktop system case to fit all of the parts in te computer. It is possible to have much of the system outside of the case, but then it would take up space in or around the desktop. When installing the system it is very dangerous for the computer parts inside.

 

 

 

 

 

Is it worth getting?

Liquid cooling is still only really effective for those people who are interested in over clocking their computers well beyond what air cooling will allow. Since the size is so big, and the intsallation is still difficult, it is not needed for a general computer.
