Trying to determine the style of wire-terminator used here so I can buy a few. What is this called? It's on the wires for a three-wire fan used in a desktop's power supply.

    \$\begingroup\$ looks like someone pulled the contacts out of the connector shell ... is the connector shell glued to the motherboard? \$\endgroup\$

  • \$\begingroup\$ I pulled them out of the connector shell. The connector was just going to the three-pin terminal for the fan. \$\endgroup\$ Commented Apr 18, 2022 at 19:48
  • \$\begingroup\$ The connector shell may help to identify the contacts you show - similar-looking contacts may not be compatible between manufacturers, or even between different connector families within one manufacturer. \$\endgroup\$ Commented Apr 18, 2022 at 21:07
  • \$\begingroup\$ @GrantCurell they are contacts specifically designed for that type of connector shell. They go with the shell \$\endgroup\$ Commented Apr 21, 2022 at 19:14

    \$\begingroup\$ Previous experience :) Have put some fan headers on PCBs before so was easy to look up the part number and the mating connector + contacts. \$\endgroup\$ Commented Apr 18, 2022 at 19:57

PC fans use the Molex ‘KK’ type.

    \$\begingroup\$ The universal Molex crimper for these (63811-1000) is $63 which is shockingly reasonable for Molex. You can also get pre-terminated 30cm jumpers with a crimped terminal on each end for about $1 and splice them onto the wires you need. \$\endgroup\$
