What Is a DC Cooling Fan?

For high-performance computer parts, heat is a serious threat. As components gain new capabilities, additional levels of heat are generated. This creates a significant problem. Many consumers rely on DC cooling fans to keep processors operating at safe temperatures. It is important to consider various cooling options when controlling heat in a personal computer.

Cooling a CPU

A computer's CPU can operate at high temperatures. For example, some computer parts work while heated to temperatures slightly lower than the boiling point of water. These harsh temperatures cause damage over time. If you control the heat in your computer, your components will last much longer.

The CPU is often troubled by the temperatures of other components. For example, your CPU might be positioned above a PCI slot. If this expansion slot is filled with a powerful graphics card, heat may rise. This might jeopardize the condition of your CPU.

It is important to understand cooling techniques that can be used to preserve the lifespan of your components. Most processors are seated in a special place on the computer's motherboard. Computer processors are often cooled by heat sinks with fans. These heat sinks are placed directly on top of the CPU using a special type of glue called thermal paste. This thermal paste helps the CPU dissipate heat. Some heat sinks incorporate the use of a DC cooling fan to reduce temperatures.

Also, additional case fans can be used to control the temperature of your CPU. Intake and exhaust fans provide necessary air circulation for your computer. You might choose to use a DC cooling fan in another location in the case to help cool your processor.

What Are the Differences Between an AC and DC Cooling Fan?

The terms AC and DC refer to types of power. As this distinction relates to cooling fans, the efficiency and power consumption are significantly different. DC fans last much longer than AC alternatives. In the past, this improved performance involved a higher price tag. Current market conditions make the DC cooling fan affordable for most consumers.

A DC cooling fan consumes very little power when compared to alternatives. These fans offer higher speeds when more voltage is applied. With a proportional relationship between voltage and fan speed, the level of cooling remains ideal for the voltage of the component. This is an efficient way to determine the appropriate fan speed for most applications.

A DC Cooling Fan Will Improve the Lifespan of a CPU

The average processor comes with a heat sink. However, fans often break down over time. Additionally, some consumers face performance problems when components overheat. A DC cooling fan might provide the proper airflow to keep a CPU in good condition.

A heat sink with a DC cooling fan might yield lower temperatures than other options. Also, an axial fan could increase airflow. Consumers can purchase a DC cooling fan for use in other locations in the computer's case. These axial fans lower the temperature of the CPU as well. For those in search of options to keep a processor cool, a DC cooling fan will provide necessary airflow.
