In the motherboard PWM speed control， the speed is adjusted to 10% or less are 1050 rpm， 10% to 100% increase each fan adjusting a level 405 turn， due to the motherboard current limit， it can not reach 5500 rpm.
12V power supply directly connected to the positive and negative power supply 2-pole， to achieve maximum speed.

Note: Please note that the fan violence is very， very good safety test， do not be finger blade to cut， high-speed rotation of the fan blades 11 when just 11 sharp knife as ruthless cutting the wind， if the finger into the cutting range， will be merciless cut down ... to when.
