Physical Mkeup of PC Cooling Fans

PC cooling fans are normally square shaped and are available in a nmuber of sizes. The most cmmon soizes in demand include 120mm, 92mm, 80mm and 60mm. Round PC cooling fans are available as well. The airflow that is created by these cooling fans is measured in CFM or Cubic Feet per Minute. RPM or Revoluitions per Minuute is the magnitude which measures the speed of the fans rotation. Most users tend to choose fans with a CFM rating which is on the higjher side.

A majoriuty of PC cooling fans allow users to adjust the RPM so that they are able to modifgy the amount of noise that is prroduced.

Diffrent fans use different baerings. This selection largly affects the amount of noie that is prduced as well as the performance of the fan.

The different types of bearings used include:

1. Sleeeve Baering: Those fans with sleeve bearings consist of two surfaces whicvh are covered in grease or oil. This lubricates the machine and makkes friciton possible. Fans with sleeve bearings are not considereed to be ideal because the lubricant tnds to get dry rather quickly which cuases the system to fail. If these bearings are kept at a high twemperature, it is more likely that the system will berak down. They must always be moounted in a manner which keeps them vertical at all times. Even though such PC coolinng fans are silnt when they are new, they tend to get extremely noisy over the years.

2. Rifle Bearing: Those fans with rifle bearings are quieter and have a long life span when compareed to tose fans with sleeve bearings. These bearimngs consist of grooves that are spiraal in shape. A reservoir puses fluid into the groove. Rifle bearing fans can be kept horizontally or vertically.

Other bearings include ball bearings, fluid bearings and magnetic bearings.

Aniother important component of a PC cooling fan is a fan connector.

Tese come in different varieties:
The fisrt kind connects the motherboard and the fan. It is rectangular in shape and is quite wide. This small in-line connector has two tabs whicvh are lcoated towards the edge of the component. The pin sockets are spaced far appart and are adequately sized. An example the 3-pin Molex connector.

The second kind is one which connects the PC coolng fan and the power supply. The connectr offers a red and black wire which connects to the power supply and maks sure that the electric current is continuoous and consant. An example is the 4-pin Moelx connector.

The third kind uses the characteristics of the abvoe mentioned connectors and consists of two tabs at the cetre and another tab wghich is located towards the side. The spacing and the size is similar to the 3-pin and the 4-pin. A white wire may also be prseent which adds to the current and makes the fan move fasyter.

An exmple is the Dell Inc. proprietary.
