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 ...

At first, it's not a good idea to put the provider link to an unofficial device. They've been checking the current that phones are using and it's easy to figure out you are using an unauthorized or an unofficial device then you may be warned by them.
However, to solve this problem, you should put the provider link to a phone and get an output link from the ...

Yes, you can use Rpi to control a 5V relay with its switch
contacts/terminals (COM = Common, and NO = Normally Open), connected
in parallel to the two terminals of the shake switch.

It's possible to make what you have work, but I'll warn you from experience it's tedious and time consuming.
Remove the connector (carefully) and cut off the end of your cable taking special care that the cut is perpendicular to the cable.
Using a single-edged razor blade or a knife with a thin, sharp blade, split apart each of the individual wires at the ...

It seems that it is not possible with common ribbon assemblies. Instead i just made and an adaptor board as suggested by @tlfong01
This is currently its PCB footprint would look like and would use right angle female headers and ordinary male headers. The ribbon would attach to the male headers and the female headers will go to the bottom of the hat.

You can use a high side switch with a mosfet and control it with the power bank's charge input, just like you wrote.

Both ports 2 and 3 were having this problem. I moved to another two ports (4, 17) and that fixed the issue. I don't know why 2 and 3 are cursed.

It is known that the Raspberry Pi 3 may have problems with some devices to boot. But you can use a special bootcode.bin-only boot mode. This will use a SD Card containing only the file bootcode.bin. Once bootcode.bin is loaded from the SD card, the Pi continues booting using USB host mode. How to setup this you can look at Raspberry Pi boot modes.
