You can Connect a 4th fan than has a molex connector, some thing like this Google Image Result for *i995.photobucket.com/albums/af72/royfrosty/coinfan_zpsd0d0bf43.jpg into your power supply.

Look for a 4pin y splitter which will enable you to connect 2 case fans to a single header Amazon.com: PWM Y Splitter Cable Adapter: Computers & Accessories

I am assuming you have 4 pin header and pwm fans?
If you have a non pwm fan i.e. 3 pin fan then you will have to buy a 4 pin to 3 pin adapter.

Or else you can also connect it to molex connector directly from psu but then it will not be controlled by motherboard but will run on voltage at max speed.

If you connect 2 fans to a single header then make sure its either both exhaust or intake.

If its a 4 pin header i.e. fans will be modded by temps .
So its better to have it bundled as intakes or exhausts instead of keeping mixed exhaust and intake on a single header.

You can connect it to your psu molex by using an adapter like this - Computer FAN 4-Pin IDE Power Connector to 4 x 3-Pin Fan Connectors (5V, 7V, 12V)

or if you want to connect it to your motherboard

Enquire in local computer shops regarding a 4 pin to 3 pin y splitter cable. You will get it cheaper as compared to online.
Incase you can't find any and still want to connect it to mobo then you can use deepcool fan hub
