There are various types of computer fans and CPU cooling fan is one among them. CPU Cooling Fan can be any fan inside a computer case used for cooling purposes or to thrash out the heat. The components in a computer system carry on various activities or operations and while carrying out these they produce large amount of heat. The heat generated must be dispersed with an immediate effect else they may have some adverse reactions in damaging computer components.
Computer Fans are used to disperse the excess heat generated and keep the equipment cool. The process of expelling heat using fans or any other hardware devices is sometimes referred as Active Cooling. A Computer Fan either throws the heat away or transfers the heat across heat sink. Improper maintenance of heat generated may reduce the life span of certain components like circuits, chipsets, RAM or hard drives.
Central Processing Unit has three or four fans attached. Personal computers built in good, old days had no proper device to ventilate the heat, they just had an aluminum sink with one or no fan attached. As the usage of computers increased there is a huge necessity found to install certain heat ventilating equipments like fan to increase the performance of the computer. Computers today carry on various multiple activities and are used everywhere. Computers today are used more then 20 hrs in a day, hence just an aluminum sink is insufficient to carry on the ventilating process. Cooling fans are the most efficient and economical method used to ventilate the heat and cool the equipment.
CPU’s carry on various operations, these operations increases the temperature of certain components and starts’ multiplying the energy or heat, the heat generated each time is equivalent to the heat lost and the heat observed in the surroundings of the system. If this heat generated is not maintained or thrown away they are high chances of loosing or damaging certain components. The computer may stop working if the heat increases the normal level. Efficiency and high performance of the computer or CPU very much depends on the level of heat generated and controlled.
CPU Fan is mainly used to cool the CPU or Central Processing Unit. Certain components are individually cooled and CPU cooling fan is one among them. They are many solutions to cool the equipment apart from cooling fans. CPU Cooling Fan is a very efficient way of cooling the CPU. Still there are certain hindrances found which obstruct the smooth running of these fans. For example dust, which reduces the efficiency and performance of cooling fans. Poor airflow or heat transfers are also some examples which reduce the efficiency of cooling fans.
It is true the computers or CPU’s generate heat but they don’t do it all the time unless they are used to operate some high end software or a program. Using computer for long hours and with some bench mark software.
