Updating:
the guys of the www.moddiy.com told me that propably there was an error with my purchase and they are going to send me the correct connectors without charge..
Really great service...
WiSK thank you for all your help..
will update as soon as the correct connectors arrive ;)
i checked their site...
there is nothing like it.. so probably there wasnt a mix up
tomorrow i will post a photo side by side of the 2 connectors..(original and the one i bought)
i did bought the adapter...
so i ll wait patiently for adapter + fan to arrive...
btw this is the fan right?
