No i meant the power connector (the 3-pin cable that goes into the MB). it is a 3-pin cable but there is only one conductor and the other 2 are just empty. and i am not sure that is how it should be and it may behave odd because of that?
i dont know how to word it otherwise at the moment.
and if it correct that way: i closed the service, i tried all usb onboard slots and also an external connection but the led wont light up. the pump is working fine except that and i can see the temperature and all that stuff in iCUE
