Appears to possibly be a factory second due to the 3-pin connector and third wire cut short near the hub. Still perfectly adequate as a normal 2-pin fan, though. Fairly quiet and moves a decent amount of air when running off a direct 12v. The wires are very short (approximately 10-12cm), however, so alteration may be required depending upon where and how you plan to mount it. Also be aware of the 3-pin JST-XH connector fitted.
