Conclusion: The fan utilizes the 12V line directly from the molex through the power supply. Since there are LEDs, power drawn using a 3pin connect would have been too much. The power wires are wrapped in a braided cover to keep everything neat.
Pros: Clear fan design, 3 evenly distributed blue LEDs, Wires wrapped in braided cover, RPM monitor cable included
Cons: Does not cool well, Directional arrows are covered by the power strip, Might be a tad pricey for some
