This is a fantastic fan extension kit for Phobya that should be purchased for any multi-fan build. Running out of a very simple, staple part during your build is incredibly frustrating; with this kit you'll never have to worry about fan tails being long enough for motherboard headers! Three, 80cm 3-Pin Fan extensions are included. Since the connectors are unshielded, these cables will also convert 4-Pin PWM to 3-Pin Fan.
