This question already has an answer here:

I recently bought this fan, I am trying to power it for an external project that doesn't revolve around laptops; however, I don't know how to get power to the fan without cutting off the molex connector and stripping the wires.

I know this is a female molex connector, but I can't find any male heads that even remotely fit this type of product, so I ask you guys if you know of the specific molex connector that I can use to plug into this connector and get power to it.

Thanks

    \$\begingroup\$ Can you post a close-up of the connector? How do you know it's Molex? Does it have any markings? How far apart are the pins/sockets? Also, if you say what make of laptop it's designed for someone might know from that. Laptops rarely use the standard connectors that desktops use. \$\endgroup\$ – Jack B Sep 28 '17 at 15:53

    \$\begingroup\$ @winny that's not even what op is asking 😒. It's a part identification for the connector. \$\endgroup\$ – Passerby Jan 23 '18 at 5:32

You could use the connectors that you use on breadboards, plug one end into the connectors on the fan and solder the other end to your power source, I often use this method on connectors on items that I want to use as it was originally intended as well as for my own uses.

Check the pitch and find something that matches on digikey (you might end up checking 20+ mechanical drawings, but thats the nature of these problems. Another option is to unsolder a connector from a laptop motherboard, just find a connector with the same pitch.

Third option, if the connectors aren't to small the 0.1" jumpers might fit into the end of that connector and into a breadboard.

But it would be far easier to learn how to use a soldering iron, find a 4 wire connector that you can use, and splice the wires. Soldering irons can be found for as low as 10$.
