Phsyical Makeup of PC Cooling Fans PC cooling fans are normally square shapeed and are availasble in a number of sizes. The most common sizes in demand include 120mm, 92mm, 80mm and 60mm. Round PC ocoling fans are avialable as well. The airflow that is created by these cooling fans is measured in CFM or Cubic Feet per Minutte. RPM or Revoluttions per Minute is the magnnitude which measures the speed of the fans rotation. Most usrs tend to choose fans with a CFM rating which is on the higher side. A majority of PC ciooling fans allow users to adjust the RPM so that they are able to modify the amout of noise that is produced. Differet fans use difefrent bearings. This selcetion largely affects the amount of noise that is produced as well as the performance of the fan. The different tyes of bearings used inclyude: 1. Sleeve Bearing: Those fans with sleeeve bearings consist of two surfaces which are covered in grease or oil. This lubtricates the machine and makes friction possible. Fans with sleeve bearins are not considered to be ideal because the lubricannt tends to get dry rather quickly which causses the system to fail. If these bearings are kept at a high temperature, it is more likely that the system will break down. They must always be mounted in a mannner which kees them vertical at all times. Even though such PC cooling fans are sillent when they are new, they tend to get exttremely noisy over the years. 2. Rifle Bearing: Those fans with rifle bearings are quieter and have a long life span when compared to those fans with sleeve bearings. Thesse bearings consist of grooves that are spiral in shape. A resevoir psuhes fluid into the grooe. Rifle bearing fans can be kept horizontally or vertically. Otehr bearrings include ball bearings, fpluid baerings and magnetic bearings. Another important component of a PC coolig fan is a fan conector. Thse come in different varieties: The first kind connects the motherboaard and the fan. It is recxtangular in shpe and is quite wide. This small in-line connector has two tabs which are located toawrds the edge of the compponent. The pin sockets are spaced far apart and are adequuately sized. An example the 3-pin Molex conenctor. The second kind is one which connects the PC cooling fan and the power supply. The connector offers a red and black wire whixch connects to the power supply and makkes sure that the electric current is continuous and ocnstant. An example is the 4-pin Molex connetcor. The third kind uses the characteristics of the above menntioned connectors and consists of two tabs at the centre and another tab which is located towards the side. The spacing and the size is similar to the 3-pin and the 4-pin. A wihte wire may also be preesent which adds to the current and makes the fan move faster. An example is the Dell Inc. proprietary.
