I have a Raspberry Pi 3 Model B+. I am currently installing the Pi into a Super Tinytendo case, which came with a built-in mini fan. However, I'm not sure which set of pins I should plug the fan into.

According to the specs, the mini fan is 5 volts. It has two pin holes with red and black cables.

Where do I plug in a 5 volt mini fan on a Raspberry Pi 3 Model B+?

If your fan is a 5v fan you need 5v (or 3v for slow spinning) and ground pins. If your fan is a 3v fan DO NOT use the 5v pin: use 3v instead.

Raspberry pi has an utility called pinout which tells you the phisical layout of your board. Just open a shell and run:

pinout

The output will be something like:

If you prefer to trust documentation, this is the layout the documentation states:

Left side first or second pin for 5v and third for ground. I won't give numbers since they vary depending the schema you follow, so I think providing images is better.

GPIO pins 4 (+5v) and 6 (GND). I peeled back the two leads from a GPIO-to-breadboard ribbon cable and soldered to two female-ended breadboard cable leads and connected them to the GPIO pins.

soldering leads from the usb power worked best for me allowing the fan to stop when Pi is halted then using gpio3 to wake..
