Types Of Computer Fans

Learn about Types Of Computer Fans. A computer fan is a fan present within the computer in order to get an active cooling. The main function of the computer fan is to discharge the warm air from the inside of the computer and draw cool air from the outer side. A lot of heat is created in a very short period of time due to the enhanced rate of data flow by the processor and it is very necessary to remove this heat. Besides CPU fans, heat conducted sinks are also used to take out this heat which can be source of damaging the computer. There are many types of computer fans and cooling options available to get rid of this heat.

One of the most common and basic type of computer fans is of fan-free heat sink or air cooled. Typically, there is no fan attached and depend completely on the fan of the computer’s case and they usually have plastic sleeve that are helpful in connecting the case fan and heat sink. Another type of computer fan is of fan-free heat sink that is liquid-cooled. Mostly, the computers featuring a liquid cooling system have a specific heat sink that permits the coolant to pass through it, ultimately taking out the heat from the CPU. This type of computer fan is considered to be very efficient, however the liquid cooling system needs to be maintained as well as observed properly so as to prevent over-heating.

Integrated heat sink and CPU fan is the type of computer fan that is actually powered with the help of a tiny power cord which is plugged into the motherboard. Another type of computer fan is named as single-speed CPU fan and this type was generally found in the older CPUs. In this type, the fan normally run at a fixed speed no matter what amount of heat is created by the CPU. As compared to other categories of computer fans, the single-speed CPU fan is considered to be less expensive. Nevertheless, the cooling produced is not that efficient as they can’t adjust their speeds to make variations in the CPU.

Multi-speed CPU fan is the type of computer fan that features a detector which permits the motherboard of the computer to supervise the RPMs of the fan and adjust them accordingly. This helps the fan to twist quicker when the computers gets hotter, therefore drawing much more heat which keeps the CPU cool. However, in case the computer is slugging and the overall temperature is low, the speed of the fan can be decreased to preserve electricity and avoid the unwanted wears on the constituents of the fans.

Mostly, brushless motors are used in the computer fans and they usually have only two wires. The brushless motors are considered to be much effective as compared to the motors having brushes. Some types of computer fans have sleeve bearings while others have ball bearings. In addition, rifle bearings, fluid dynamic bearings, magnetic bearings, and ceramic bearings are also used in some types of computer fans.
