I plan on replacing the H100i GTX fans with corsair SP 120 Red LEDs because they're noisy af but I cant remember where to plug in the 3 pin (i think) on each of the fans onto the motherboard. Mobo is a Gigabyte GA-Z97X Gaming 3. The H100i GTX has just one connector for both of the fans it looks like, but if I buy the fans individually then I'll have 2 connectors for each of the fans.
