Confused over how to use the hubs.

I bought 3x Single Pack 140mm TL Lcds. Couldn't buy them in a 3 pack for some reason. Then I had to buy a seperate TL Controller. Okay sorted that out. Shipping time is nuts.

I bought 6x 140mm SL-INF fans, reverse blade, also wasn't available anywhere as a 3 pack. I was told you can't use SL fans on the TL hub. Okay. I bought the SL-INF hub as recommended. I don't have a single 7 pin anywhere in the SL packs to link to the hub, which defeats the whole point. I don't want to run the fans to the motherboard, I want to control everything thru Connect.

I have 2x extra TL Lcd cables, which seem to fit into the SL fan... but I'm getting conflicting messages here if it'll work if I plug that cable onto my SL INF fan 3 run, and plug into the Sl-INF controller.

This whole ecosystem is the most user unfriendly thing I've ever seen. Need some advice before I pack everything back to Amazon. $600 and counting in fans, hours of research, and I've zero clue if I have everything I need yet.
