DC axial fan
NMB Technologies Corporation
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.
