Gamesir X2 Fan Mod (UPDATED)
Update: For some reason I encountered stability issue when using Gnd from the spring connection beside 3.3v spring. So I rewired it again using the Gnd pad next to 5v pad. And this is how I actually wired it in the very 1st version where I had a coiled wire sticking out on top instead of a sliding contact.
This mod adds fan noise.
Also I tested just running 1 fan thru otg adapter and battery drain is about 5% after an hour (screen was off).
For disassembly, I followed this • GameSir X2 Teardown
Then I just drilled with a dremel like tool and glued them into place. I used epoxy on the fans and switch as this is all I have. And tiny amount of super glue on the back of nickel strip.
And the basic goal here is to just connect the fans to the 5v and Gnd pads in that board.

Other FYI/ideas
I tried to replace the 3.3v on the spring with the 5v, so I can move 5v to the other side without using any other wire or sliding contact. But I don't have a chip to drop the voltage. And only tried via voltage divider. I encountered problems this way, the right board drops connection when both fans ON, led does not work, and X2 itself drops connection after some time.
