My laptop's power supply to the fan gave up and I want to reroute it. My plan is to use power from the USB. And I want to make it clean, with connectors instead of soldering (where applicable).
The fan uses a 4-pin connection to regulate the RPM. I have purchased a small controller. However I did not realize there was a difference in size. The fan uses a 6mm 4-pin and the controller a 10mm 4-pin.
I want to purchase the respective male and female headers. I would like to know what they are called so I know what to look for.

As @Nick Alexeev said in the comment, it's propably a Molex PicoBlade.

Can't be sure only looking at your picture. If it would be me, I would get a plug that fits into your controller since you can see exactly what kind of connector you need from the controllers datsheet and replace the small connector from the fan. Soldering wires is not a bad thing either but wires have a habit of breaking off pretty easily. Hot glueing around the solder is a cheap man's trick thats not pretty but works.
