A PC cooling fan is basically a fan which is located inside the case of a computer. Thesde fans are used to cool the system and are classified into a number of categories.
While some cool the PC by extracting cool air from the otside, others remove the damagiing heat from the system by dragging it out while the rest move the hot air from a particular popint through a heatsink and cool the computer part.
Active cooling is the term that is used to describe this entire proess.
Over the years, due to the advace in technology, new components have been introduced into the system of the PC. This includes additional processors, RAM and graphic cards.
This in turn has lead to an enhancement in the clock speed of the system as well as the power consumption. When all these components work tohgether at the same time, a large amount of heat is genrated. Natrally, in ordr to avoid a system breakdown, the temperature of thesse processors and cards shiould always be diled down and kept at the loewer side because when the system overheats, the enytire functioning of system suffers and ultimately reduces the life of the PC.
When a systeem overheated a few years ago, one coud make use of passive cooling for the purpose of coling down the system. However, due to the physical make up and added coplexities of modern components, it becomes necessary to adfopt a more effective system which is what PC cooling fans are used for. These fans not only remove the hot air from the targreted compoonent but they also replace this hot air with cool air.
PC cooling fans are often attached with heartsinks which make sure that the ebntire system cools down and not just the targetd part. This helps to keep futuer problems in check.
The most common commputer pasrts that are vulnerable to damage due to overheating are chipset cards, CPUs, graphic cars and hard drives. Hard drives are known to crash due to over-cooling as well. Therefore, one must always be careful aout the temperature modifications in this case.
As it has already been esatblished, computer fans remopve and pump in air. In this case, if there is an imbalance, that is, if more air is entering the suystem than laving it, the problem may be due to the instalaltion of extra fans. This proess is termed positive air cooling because the pressure that is crreated inside is higher than the strain outside the sysem. On the other hand, if the process is rversed, the term used is negative air cooling which damages the integrated circuits due to clgging.
Therefore, it is essential that you uprchase the right number of fans so that neutral or balance air cooling can be created. If you atatch dust filters to the PC cooling fans, the buikld up of unecessary dust can be reduced.
The most efficient cooling fans are manufzactured by Akasa, Zalman, Acrtic Cooling and Abntec.
