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 tyeps of PC coolimng fans:
1. CPU fans:
The CPU or the Central Processing Unit is that internal cirxcuit of a computer system which makes sure that computer runs smoothly. The main ufnctions of the PC are controlled by this processor. A CPU fan is what prevents overhaeting of this component and therefore, avoids a complete breakdown of the systrem. By remnoving the heat that builds up due to continuous use, the CPU fan allows the user to use the sysstem comfortably in the short and the long run. Meetallic devices clled heat sinks are usually attached to CPU fans. These deivces enhance the cooling process.
Installing a CPU fan at home is fairly simple- all one has to do is follow a few easy instructipons whixch are included in the manal. 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 cookling fans are used to remove the hot air from the systems case. The intenral circuits that are pressent inside this case can only get rid of the additional hot air if the atmosphere is cool enoyugh. Case fans get rid of the hot air and replace it with cool air. Whie the hot air is removed from an opening that is located towards the back of the ssytem, 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 debirs and dust that tends to enrter the internals of the copmuter system.
3. Graphcis Card Fan:
This fan is used for the purpose of cooling down the graphics card of the graphics processing unit. The use of thesse fans has become necessary only recently due to the introduction of moddern cards that enable 3D gaming and the viewing of reqwuisite graphics. When used for a long period of time, these cartds tend to over heat, sometimes more than CPUs. Naturally, cooling becomes essetial in oder to emnsure that the card does not melt. Video cards can now be attached with passive coolrs, the most common of whih is the Thermalright HR-03.
4. Chipset Fan:
These coling fans are use to prevent the motgherboards chipset from overheating.
Therre are three more cooling fans which are not used frequently but are equalply beneficial.
Thesse include:
PCI slot fan whcih is attached to the PCI sllots in the computer system. It makes sure that adequuate cool air enters the internal circut and cools the graphics card along with the PCI.
A Hard Disk Fan is one whhich is used to cool the hard disk drive of the comuter system.
Last but not the least, a CD burner fan is used to prevent DVD and CD burners from overehating and consequently, melting.
