I have a corsair 600t and a CX500 PSU.

The 600t comes with 1 exhaust fan, and 2 big fans on top and front. It also comes with a fan controller that has 4 plugs and 1 molex.

My mobo is a b85m-g43. and it comes with 2 "other than CPU" fan spots.

I have no clue at all how to connect the 3 case fans to the controller, since the controller's plugs look totally different and are also female.

i also have no idea how to use the molex connector because all it is is 4 fat prongs on one side and 4 fat holes on the other.

on the PSU there's also nothing in the world i can seem to hook my 3 fans into. i'm incredibly lost.

This is my final step before i try my first start-up and it's kept me now for the passed hour and a half. please help.
 
Plug your psu molex connector into the controller molex. There should be extensions that came with the case that'll plug into your case fans.

Otherwise, use a fan splitter to join two fans to one mobo csae fan header and use the othe other case fan header for the other fan.

What do the extensions look like? Do i have to buy fan splitter or does it comes with the computer?

Good advice from the "Grandmaster".

I have a Corsair 'Obsidian' Series 650D case and a ASRock motherboard that also did not have enough fan headers for the number of case fans I was using. I bought a fan splitter in order to plug two fans into one header - problem solved. Being that I plugged the case fans directly into the motherboard and adjusted the motherboard BIOS to control the fan speed, I did not have to use the front fan controller at all which made life (and cable management) a lot simpler.
