CPU Cooling Fan also known as Computer Fan. They are small fans build inside the computer or CPU to cool the equipment and disperse the heat. Usually the Computer Systems produce large amount of heat while carrying out various operations. This heat can damage certain components of the equipment and hence it becomes very much necessary to maintain the level of heat generated.
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 PC fans 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.
Usually a CPU (Central Process Unit) contains three or four fans. They were days when PC CPU’s could get away with just a little aluminum heat sink stuck on top of them or no cooler at all, but today when these computers are used massively and carry on various operations around the clock it becomes necessary to choose a CPU which has a cooling fan. Because the faster a given CPU runs, and the higher is its supply voltage, the more heat it emits. If the cooling sink is attached to the top of the chip and can’t dissipate heat well, the CPU will get too hot and stop working.
While carrying on certain operations, the temperature certain components will rise until the temperature gradient between the computer parts and their surroundings is such that the rate at which heat is lost to the surroundings is equal to the rate at which heat is being produced by the electronic component, and thus the temperature of the component reaches equilibrium. To maintain the efficiency of the computer it is necessary to keep the structure cool. Overheating may reduce the life span of the computer.
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. There 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.
CPU’s don’t pump out their maximum heat all of the time. Unless the user loads them with some benchmark software or a program that just pointlessly flogs the CPU like crazy for the express purpose of making it hot and then they’ll emit a fairly constant heat.
