Due to frequent use, the internal circuits of the PC tend to overheat and ultimately melt if the appropriate cooling functions are not carried out. Naturally, PC cooling fans become necessary in this case. The following are the different types of PC cooling fans:
1. CPU fans:
The CPU or the Central Processing Unit is that internal circuit of a computer system which makes sure that computer runs smoothly. The main functions of the PC are controlled by this processor. A CPU fan is what prevents overheating of this component and therefore, avoids a complete breakdown of the system. By removing the heat that builds up due to continuous use, the CPU fan allows the user to use the system comfortably in the short and the long run. Metallic devices called heat sinks are usually attached to CPU fans. These devices enhance the cooling process.
Installing a CPU fan at home is fairly simple- all one has to do is follow a few easy instructions which are included in the manual. Before purchasing a CPU fan and the attached heat sink, make sure that there is enough space to fit it in.
2. Case Mount:
These cooling fans are used to remove the hot air from the system’s case. The internal circuits that are present inside this case can only get rid of the additional hot air if the atmosphere is cool enough. Case fans get rid of the hot air and replace it with cool air. While the hot air is removed from an opening that is located towards the back of the system, the cool air enters through an opening present in the front of the system. Many users recommend the use of air filters with case fans in order to get rid of the debris and dust that tends to enter the internals of the computer system.
3. Graphics Card Fan:
This fan is used for the purpose of cooling down the graphics card of the graphics processing unit. The use of these fans has become necessary only recently due to the introduction of modern cards that enable 3D gaming and the viewing of requisite graphics. When used for a long period of time, these cards tend to over heat, sometimes more than CPUs. Naturally, cooling becomes essential in order to ensure that the card does not melt. Video cards can now be attached with passive coolers, the most common of which is the Thermalright HR-03.
4. Chipset Fan:
These cooling fans are use to prevent the motherboard’s chipset from overheating.
There are three more cooling fans which are not used frequently but are equally beneficial.
These include:
PCI slot fan which is attached to the PCI slots in the computer system. It makes sure that adequate cool air enters the internal circuit and cools the graphics card along with the PCI.
A Hard Disk Fan is one which is used to cool the hard disk drive of the computer system.
Last but not the least, a CD burner fan is used to prevent DVD and CD burners from overheating and consequently, melting.
