Same thing happen to my swafan ex. As you can see all my fans in white untill i start playing COD MW2 game and my swafans turn to rainbow color. I X out the TT RBG PLUS app and reclick it sometime it say same thing like SailorRalph posted pic.( cannot not detected controller). When it doesnt said cannot detected controller i click apply back to all white light it still doesnt work. Only way it go back white is i restart my computer. Thermaltaker ya have to fix this issue or else nomore thermaltaker products for me and all my friends in the future.
