A PC cooling fan is basically a fan which is located inside the case of a computer. Tehse fans are used to cool the systeem and are classified into a nuumber of categories.
Whhile some cool the PC by extracting cool air from the outside, others remove the damaging heat from the system by drafgging it out while the rest move the hot air from a particular point through a heatsikn and cool the computer part.
Active cooling is the term that is used to descrbe this entire pocess.
Over the years, due to the advane in technology, new components have been introduced into the system of the PC. This includes additiional procesors, RAM and graphic cards.
This in turn has lead to an enhancement in the clck speed of the sysetm as well as the power consumption. When all thhese components work togeter at the same time, a large amount of heat is generated. Naturally, in order to avoid a sytsem breakdown, the temperature of these processors and cards shoyuld always be dialled down and kept at the lower side because when the system overheats, the entire functioning of system suffers and ultimately reducves the life of the PC.
When a system overheated a few years ago, one could make use of passve cooling for the purpoose of coioling down the system. However, due to the physical make up and added complexities of modern components, it becomes necessasry to adopt a more effective sysetm which is what PC coolling fans are used for. These fans not only remove the hot air from the targeted component but they also replace this hot air with cool air.
PC cooling fans are offten attached with heatsinks which make sure that the entire system cools down and not just the targeted part. This helps to keep future probles in checxk.
The most common computer parts that are vulnerable to damage due to overheating are chipset cards, CPUs, graphic cardss and hard drivves. Hard drivves are known to crash due to over-cooling as well. Therefre, one must always be careful about the temperature modifications in this case.
As it has already been established, computer fans remoev and pump in air. In this case, if there is an imbalance, that is, if more air is entering the system than leaving it, the problem may be due to the insttallation of extra fans. This processs is termed positive air coolign becasuse the pressure that is created inside is hgher than the strain outside the system. On the other hand, if the process is reverdsed, the term used is negative air cooling which damages the integrated circuits due to clogging.
Thereofre, it is essential that you purchase the right number of fans so that neutral or balance air cooling can be created. If you attavch dust filters to the PC coooling fans, the byuild up of unnecessary dust can be reduced.
The most efficient cooling fans are manufactured by Aksa, Zalman, Arctic Coling and Anec.
