DC Axial Fans

When investing in DC axial fans it’s best to understand more about these fans and how they function.

What Are Axial Fans?

An axial fan in general, whether DC axial fans or otherwise, is the most commonly used variety of cooling fan, as well as the most cost effective. Also called ‘box fan’ on occasion, they move air on a straight axis through the fan. This kind of fan functions best under a low pressure or low system impedance environment. With reduced fan speed the noise produced by an axial fan can be kept at a minimum. Because of this low level of audible noise, as well as their economical price range, this kind of fan is extensively used in PCs, for both CPU and power supply cooling.

DC Axial Fans - Functioning

A DC axial fan pushes air in a direction that is parallel to the track of the fan blade axis. This kind of fan reaches maximum efficiency under low static pressure conditions.

AC and DC Axial Fans – Which is Better?

When it comes down to it, different systems require different types of axial fans. Some require AC while others require DC. So although there are differences between the two, you need to make sure you purchase the correct type. But, in case you were curious how AC fans differ to DC fans, here are a few historical and current points.

Due to the higher cost of a DC fan in the past, AC fans were in predominant use. Now that the price point of a DC axial fan has become more reasonable, the many advantages of the DC fan over the AC had made it the top choice for CPUs.
A prime advantage a DC axial fan has over an AC fan is a longer life span.
A DC axial fan also consumes up to 60 percent less power than an AC fan. In fact, experts have proven that a 10°C increase in fan temperature can reduce a fan’s life by as much as 20,000 hours.
Another big advantage of a DC axial fan over an AC fan is that the speed of DC fans are directly proportional to voltage, thus allowing them to run at the speed required for adequate cooling.

In essence, DC axial fans direct heat outside of a motor, keeping your CUP running at an optimum level.
