What is the type of speed axial fans

　　In the purchase of axial fans are the first time to consider is the cooling fan manufacturer qualification, quality of products, product size, finally, whether the product has had thermal performance, these sources we think you can do the Wind to.

　　However, for axial fan speed played a decisive factor and what it?

　　Axial fan speed can be divided into two kinds of strong type and silent type.

　　Powerful and silent type distinction is not too strict, but the same size, the same voltage for computer fans, air pressure and noise will always be two irreconcilable contradictions. Fan speed is the number of revolutions per minute fan fan page, the unit is rpm. Fan speed is determined by the motor inside the coil turns, voltage, number of fan fan pages, inclination, height, diameter and fan bearing system. At a fixed fan structure, the DC fan (i.e., a DC-powered fan) of the speed of change of the operating voltage changes in synchronization. The fan speed can be measured by the internal speed signal can also be measured (external measurement is to measure the speed of the fan with a special red line speedometer, internal measurements directly into the BIOS can see, you can also look through the software via the outside. Internal relatively large number of measurement error). Cooling fan

　　Axial fan speed and cooling capacity and not necessarily related to a higher fan speed but will result in higher noise, if the amount of wind almost, you can select low speed fan cooling fan when purchasing products, some quiet during use .
