I have a 40mm fan with a connector that has standard breadboard pin spacing. I would like to connect it to what I thought was a relatively standard fan connector that has wider spacing (and thicker pins).

In the image below, the fan is wired to the connector on top; I'd like to connect it to the connector on the bottom:

What is the name of the larger connector? That would make it easier to find an appropriate adapter.

They are both: single-wall wire-to-board connectors. But ...

Note: even if you have the matching plug, that doesn't mean that it will work. We don't know whether the PCB male header is intended for a fan, and, if it is, what its pinout and signaling is.

    \$\begingroup\$ Thanks, that looks like a great reference! We do know that the PCB male header is intended for a fan, and we also know the pinout of the connector matches the fan. \$\endgroup\$
