Hey guys,
I have had my PC for around 4 months now and want to get 2 more fans as my case (http://www.bitfenix.com/global/en/products/chassis/comrade/)
has one already at the back and has already taken the SYS_FAN2 3 pin slot on my motherboard (http://www.gigabyte.com/products/product-page.aspx?pid=4591#ov)
As I have two headers left: PWR_FAN and SYS_FAN1. If I were to buy two more fans how can I make them compatible? What will work with what? Does 3 pin work with a 4 pin header? (Im getting 120mm obviously)

Ok thanks man, so the labels can just be ignored i'm guessing?- it doesn't really matter what they say
