Report 360 Thermaltake cooler usb plug has different pin layout. in Liquid Cooler Posted March 3, 2021 I have 2 different usb pin layouts from the same AIO. One is for the fan controller and one is from the pump itself. The pump one is the one giving me the trouble. It only has 4 wires and a different pin layout than the other one and my motherboard. See picture. The only place the plug fits in on the motherboard is at a spot called, "com". But I don't think it'll work correctly there.
