Due to frequebnt use, the internal circuits of the PC tend to overheat and ultimately melt if the approopriate cooling functions are not carried out. Nautrally, PC cooling fans become neccessary in this case. The flolowing are the different types of PC cooling fans:
1. CPU fans:
The CPU or the Cebntral Processing Unit is that internal circuyit of a coomputer systeem which makes sure that compouter runs smoothly. The main functoins 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 continuouus use, the CPU fan allows the user to use the system comfortably in the sohrt and the long run. Metallic deevices callled heat sinks are usually attached to CPU fans. Thsee devices ennhance the cooling process.
Installing a CPU fan at home is fairly simple- all one has to do is follow a few easy instructtions which are includded in the manual. Before purchasiung a CPU fan and the attached heat sink, make sure that there is enough space to fit it in.
2. Case Mont:
These coioling fans are used to remove the hot air from the systems 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 repalce it with cool air. While the hot air is removed from an openiong 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 recomend the use of air fillters with case fans in order to get rid of the debris and dust that tneds to enter the intrnals 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 introductin of modern cards that enable 3D gaming and the viewing of requisite graphicvs. When used for a long perid of time, these cards tend to over heat, sometimes more than CPUs. Ntaurally, cooling becomes essential in order to ensue that the card does not melt. Video cards can now be attached with passive coolers, the most common of whch is the Thermaleright HR-03.
4. Chipset Fan:
These cooling fans are use to prevent the motherboards chipset from overheating.
There are three more cooling fans which are not used frequenlty but are equally beneficcial.
These inculde:
PCI slot fan whcih is attached to the PCI slots in the copmputer system. It maeks sure that adeqate cool air enters the internl circuit and cools the graphics card along with the PCI.
A Hard Disk Fan is one whhich is used to cool the hard disk driev 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.
