Computer Cooling Fans

There has been a steady increase in the power and speed of computers over the past decade. This increase has been driven both by consumer demand and technological developments. If you rely on your computer, you have probably invested a lot of time and money to make sure that your computer matches your need for high efficiency. To keep your system running at peak efficiency, it's important to have superior cooling fans that can cool your system. To dissipate the significant amount of heat generated inside the system and to prevent it from overheating, computer cooling fans are the ideal solution. Fans bring in cooler air from the outside and draw hot air out from the system to cool it. Most computers have built-in fans for cooling purposes; if your system does not have one or if you notice fans that are not working properly, then it's important to repair or upgrade with fans that can meet your system's requirements as soon as possible.

Problems Caused by Overheating

Overheating can cause some serious damage to your computer and can set you back more than just money to get your system back in order. One of the most critical potential consequences is losing data. Overheating damages the components inside of the system and can cause irreparable injury or shorten the lifespan of the system's hardware. One of the main reasons that systems overheat is insufficient cooling due to lack of air flow inside the case, causing heat to build up. A system can also get overheated if one or more components inside of the machine is overworked and is generating more heat than what is normally expected, or even if the system is placed in a room that has an unusually high temperature.

Detect Failure of Cooling Fans

When a cooling fan fails, you may be able to hear a difference in the kind of sound it makes. If you hear any sounds apart from the familiar whirring coming from the CPU from the cooling fans, then it's time to check if the fans are in proper working condition. In other instances, the computer will alert you with a sound if the cooling fan is not functioning. However, not all cooling fan failures have audible indications and the failure can instead cause random system shut downs, blue screens of death, system freezes, and/or Windows error messages. Check the cooling system in your CPU immediately if you encounter these problems, and replace the fans as soon as possible if you detect fan failure. Replacing cooling fans promptly is always better than replacing an irreparably damaged computer later.

Extend the Life of Your Computer with a Cooling Fan

It pays to keep your computer cool. Check out some suggestions below which can keep your system performing at optimal levels:

  • Position the back of the CPU a few inches from the wall, as most fans are located at the back of the CPU.
  • Place your system in a clean, airy environment and keep your fans clean and free from any dust. Dust buildup reduces airflow and slows down the fan. Thoroughly clean your computer case of dust, debris, and pet hair at least once each six months with the help of a vacuum or can of pressurized air.
  • Keep the cooling fan away from fabrics, which can get stuck in the blades.

Components Inside of a Cooling Fan

Computer fans are made up of brushless motors that turn the fan blades attached to them, facilitating air flow. Copper wires are wrapped around the motor, and whenever it moves, the shaft attached to it also moves. When energized, the brushless motors transforms into an electromagnet to generate a magnetic field with north and south poles. The rotor is made of magnets that are attached to the blade assembly with a shaft in the middle. The rotor moves when it is mounted on a fan frame, also known as a stator. An integrated circuit on the circuit board controls the wires, energizes the coils, and changes the magnetic field that repels the magnet located in the rotor to keep the motor spinning. A motoring circuit feeds information to the motherboard on the rotor speed.

Bearings are also a critical component in a cooling fan; bearings make the fan rotate smoothly. It is the point of contact between a rotor and a shaft and allows the rotor shaft to spin. Bearings reduce friction, allow the fan to operate at high speeds, and are partly responsible for the life expectancy of a cooling fan in a computer and the noise level of fans. Two types of bearings can be used in a cooling fan: a sleeve bearing or a ball bearing. Either can be used depending on the fan's design.

There are different types of computer fans available engineered specifically for the system they support. If your system has low back pressure and requires low noise, then an axial fan will work very well for your system.
