  1. My rear fan has 3 connections:

    1 little plug to plug into the motherboard

    1 big plug (male) to plug into the power supply cable

    1 big plug (female) to plug into the power supply cable
    -------------------------------------------------------------------------

    I plugged the power connector to the male big plug comming from the power supply.

    ..is this right?

    Do i need to plug in the little cable connecotr to the motherboard even though the plugged the big connector to the power supply cable.

    thanks

    Case: NZXT Whisper)

    The smaller plug is so that your motherboard can detect the rpms, yes you can plug it in.

    Just plug either the big or little one in, not both :)
