Hi,I just purchased the Eisbaer Extreme 280. When I was trying to install it,I noticed 3 cables goes out from the radiatoer/cooling unit:1x4 pin with 4 wires; 1x4 pin with 2 wires and 1xMolex connection. My question is where am I supposed to plug the moles wire? By using an extension line connected to the PSU? or some special ones?
