Computer Cooling Fan

A computer cooling fan reduces the temperature in the system to ensure longevity of the computer. There are five other types of fans also, which serve the same purpose. They are CPU fans, hard drive fans, power supply fans, chipset fans and finally video card fans. Electricity passing through the different components in the computer generates a considerable amount of heat. This results in oscillation of the materials. Megahertz is the unit of measuring the rate of oscillation. More Megahertz means more heat. A computer cooling fan is necessary particularly for a CPU of 200 MHz or more.

To ensure a long life of your computer if your rig is modded, you need all five types of cooling fans. The computer cooling fans, CPU fans and hard drive fans concentrate on cooling off different parts of the computer.

There are different varieties of size and RPM speed in computer cooling fans. When buying these fans, you should always take care of the bearings, rotation speed and blade design. The standard 80 mm fans usually have one or two wiring configurations. Each of them has its own type of connector. When you use a three-pin type of fan, you can get feedback from the fan to monitor its speed. A four-pin connector of the type supplies twelve volts DC power to a CD ROM or hard disk drive. However, it does not have the speed control facility. You can also use inexpensive fan speed controls for the three-pin type of fan. These devices help you control the fan speed according to necessity at lower RPM.

When you buy a computer cooling fan, you should pick up ball bearing fans, preferably with 3 pin connectors. Here, you will have a reading of the actual rpm of the fan. You can also purchase slot-fan to have direct cooling of a hot peripheral, like your video card. This can help in blowing out the hot air out of the system.

However, among all the available options, water-cooling provides the best cooling solution. It is noise free, powerful and very efficient in keeping your system cool.

You will find single-speed computer case cooling fans that work without creating much noise. You may need to remove drives or add-in boards to replace the old fan with a new one. You should check whether the fan power is connected to a power-supply connector or to the motherboard. You need to place the external temperature sensor of the fan at the proper location.

Most of the cases have the provision of mounting an extra cooling fan at the front or at the top, near the power supply. The fan defuses the heat generated by the peripheral outside. You need to make sure that the inbuilt fan blows air outward. It will blow the hot air accumulating at the top of the case outside. This will bring down the temperature by approximately 5 to 10 degrees. To blow cold air inside the case, you can mount an extra 80mm fan in the mounting bracket at the bottom of the case.

Usually a system carries at least four fans. These fans can be either high speed or low speed fans. The high-speed fans have high airflow ability as compared to the low speed fans but, if you use a large 120mm low speed fan moves much more air. Nevertheless, the high-speed fans create a lot of noise. To keep your system cool, you need to have better airflow though the computer case. You can mount extra fans on your system. You need to keep the inside neat and free from ‘cable clutter’. Rounded cables can help you avoid this ‘cable clutter’. Even some cheap and easy case cutting can help you significantly in reducing the heat.
