howdo all. just got my new 80mm antec pro 80mm DBB case fan today. It has been provided with a 3-pin connector & 4-pin adapter with power pass through feature. I have no spare motherboard 3 pin sockets. So where would i connect the 4-pin female connector that comes from the fan. I cant see any leads coming off my antec psu that are 4 pin male. The fan only leads from the psu are not male. Please help folks, I would love help. Thanx a million.
