There should be a yellow/black 2 pin molex on the left side of your backbox behind monitor. PIC
It is 12vdc.12vJJP (resized).jpg

If you want an easy solution without building your own power tap and extensions you can buy this already made.
Standard JJP 12v power tap:

Power Kit: JJP 12v with additional connectors

JJP power splitter by itself:

The price for the kit is somewhat reasonable but you would still need to buy 2 pin molex to fit their splitter ends and you still need wire to run to the fans or mods. So I chose just the power tap bought long ago that I used recently on my DIY 5-fan(3 flippers, diverter,magnet) install on my GNR. I made my own splitter with these connectors from amazon:

I had the wire but here it is for posterity:

The diodes I bought: It helps if you have a digital multimeter to test these.

Solder wire splice kit: Good to have.

Good to have wire splice stuff: Not necessary.

Heat shrink kit: Not necessary but nice to have around.

The fans I ended up with.
I chose dual ball bearing for longevity reasons. 40x40x20 for the 3 flippers:

40x40x10 for the diverter and the magnet:

I remixed the thingiverse stl files for the fan holders but they were free because I have a 3d printer and used tinkercad to shape them the way I wanted. If you have a buddy, a local library, or a printer you can get them done cheap or free.

I'll put some pics up in another post.

Pics. Any questions, please ask. This can be done for under $50 all in. It took a bunch of time but I wanted to DIY it cause it keeps my brain busy.
I have $28 total in fan cost so it can be done even cheaper if you want to use zip ties and electrical tape. I'm not being flippant with that statement as there is nothing wrong with that method either. Function is the main goal.

Big Thanks to awesome1 for getting this going. I wouldn't have tried it otherwise.
Also SlapDrain for their contribution as well and willingness to assist us DIY'ers. Definitely SlapDrain Extended Play Coil Coolers would be the go to plug and play option as far as kit/price goes.
