Wiring / Extra Fan power supply + Cable extension

[Pouly]

HI,

i have been building a Geeetech Pro B and its looking good, this is my second printer (started with a Monoprice Mini) and understand the importance of cooling.

In that spirit, i wanted to add 2 fans to my build >
1x to cool the electronic board
1x to cool the filament

So i am heading to ebay / Amazon to order son 12v 40mm Fan 2pins, but they all have short cables and there's only 1 extra power supply for a 3rd Fan, what about the 4th one ?
I guess i am looking for help on how to power supply these fans ? Should i order 2pin extension cables (i have a hard time finding these), use a Y splitter ? Should i solder these cables ? Please provide some examples of your wiring / power setup for extra fans

Feel free to provide ebay / amz links to buy the products you recommend.

This extension cable may work:

As for the fan sockets,there are 4 ones(3 common fans and 1 PWM fan) for fans on the motherboard in total.

Thanks a lot for the answer !
The problem with this cable is its 3 pin and most fans are 2 pins.

It feels like so many people add extra fan, are they all soldering wires and adding power splitters ?

I'm not sure about that:

and that's just for this model and see how many people printed them, i am feeling a bit stupid to be the only one asking these questions, for instance, how did he wire that thing >

This is what a lot of people use to attach the 2 pin fans to the 3pin connector on the board.

Since i didn't have any on hand I just removed the pins from the fan connector, covered them with shrink wrap and plugged them onto the correct 2 pins on the board.
