Default Help connecting case fans to mobo/PSU

I've just got a Gigabyte 990FXA-UD3 motherboard, an Antec 300 Illusion Mid-tower case, and OCZ ZT Series 750W power supply unit, and I've run into a problem connecting the case fans to the mobo/PSU.

The case has 4 fans (all with three-prong plugs) and the mobo only has 3 fan connectors (excluding the CPU fan connector) with 2 three-prong connectors (marked PWR_FAN and SYS_FAN2) and 1 four-prong connector (marked SYS_FAN1). 2 fans are in the front, 1 in back, and 1 on top. All the case fans also already have speed controllers attached.

Which fan plugs go in which connectors?

What other cables will I need to make all 4 case fans run?

Either get this: Newegg.com - StarTech 12" TX3 Fan Power Splitter Cable Model TX3SPLIT12

Or this: Newegg.com - Link Depot POW-ADT-3P4 Power 4 pin adapter to 3 pin fan adapter

You don'gt need to buy anything.

You need to find the 4 pin molex adapters, that should have come with fans, and then just plug them into an empty slot of your power supply cables.

As they have the 2/3 speed controller, running them straight off the psu is the best.
