Motor
I'm not quite sure why I keep adding these images to the review articles but perhaps there is someone out there that finds these interesting... Motor is rated for 3.6 watts as was the 120 mm version. Why we need so much power as the fan is so small? Perhaps the reason can be found from the next two images.
Opened
Electricity for the light efect is not taken from the computer directly. One can say that there is a small generator embedded to the "brains" of the fan that generates electricity while the fan is moving.
Lights
On the left are the eight leds that are needed to make good quality ascii characters. These form the letters and numbers when the fan is rotating. On the far right, at the very tip of the pcb is a sigle led that draws a constant circle around the fan when it is moving.
Quite clever way to bypass all the problems that arise if one tries to transfer power from the power supply directly to the moving blades. Vibrations can be a problem but they seem to be in check with this particular unit.
