I would like to bring this thread up and help pinsider to get a "cheap" plug and play solution for some games (I used it for #Rick and Morty, #The Big lebowski and #Guns & Roses)
So for the plug and play solution I used following things:
2 Fans (40x40x20mm and specs like 5 - 6 CFM, rpm ~3000, current draw ~0.04A) like the SUNON fan liked Agima2000 used.
Molex Y Splitter (for 2-3 fans):

or

2 fan extension cable (between 11,8 and 36")

and some cable ties.
In the picture you see an exmaple for the parts you can use. And its about $70 for 2pins (2x2 Coils = 4 Coils) so about $35 for an plug and play kit if you can 3d print the coilcooler holder your self.
If you have any questions feel free to ask
