Came a cable, that looked exactly as shown (this respect so you can not blame the seller), the product name, however, is rather misleading:
The 4-pin. "Connector" is namely actually a Molex connector, so looks exactly like the Molex connector on a drive or even on the fan to be adapted, but not as the Molex connector, as they come from the power supply. In the broadest sense can be the seller, but credit, that at Molex connections socket is male (has pins So) and the female connector, however, this applies to the fan connector on the motherboard as well and the site is still correctly described.
You can connect the adapter cable so with a free fan connector on the motherboard, but then encounters sides of the fan to the problem, that of course can not connect to a socket a socket. If you're lucky (and I had only therefore has the Article 3 stars get), the fan not only has a Molex connector, but also a passage and thus a Molex connector, so that him anyway (so to speak with whose output side) can connect.
Thus, the adapter cable performs at fans with terminal durchgeschliffenem perfectly his service, for fans without pass-through port, however, it is not suitable.
Mir is doing, however, an additional question namely, what the producers may have been thinking. Probably not, because the adapter cable is just not suitable for the reverse purpose, ie a fan with PWM terminal via Molex to supply (example, if you no free fan connectors has more). The only technically fully possible use is as a "motherboard-killer", because the adapter makes it possible to connect two power sources (fan connector on the motherboard + Molex power connector from the power supply) with each other.
