thanks to TT's 1 page manual that fails to warn you about how they sync (so you can plan ahead), and a bunch of trouble shooting, ultimately i ended up using 3 controllers for 10 fans, originally i had 2.. but it took me all day to figure out you could click on the background and it would swing around to fans 4 and 5... anyway... when doing a full sync, i dont like the order, its goes fans 1-4 on con1, the jumps to 2, then 3, but fans 2-3 on con2 are out of order, and con2 also runs through 1-3 in the opposite direction i would like, and con2 and con3 are also of order relative to their position in the case.. and honestly i REALLLLLLLLLLLLLLY dont want to open my case, and start tracing wires, and re-plugging them and setting the dip switches again. i'd also have to cycle through all the fans first, and write down which one i want to plus into which spot on which controller, since id have to power down first.. and that all seems like a huge p.i.t.a. if there is a simple way to just re-assign via software. and if there isnt, TT really needs to get their stuff together in regards to that. its like they almost have it in neonmaker, but not quite.
