can I use the spare cpu opt fan header for one of my water cooling fans. my last asus z97a had 6 fan headers so I was ok but this new ranger board only has 2 for cpu and 3 for case fans. any thoughts form anyone

my last mobo was the asus z97-a and it had 6 fan headers 2 for cpu and 4 for case fans. my new mobo asus maximus vii ranger only has 5 fan headers, now I have 2 200mm fans(top and front) and I have a corsair 140 mm water cooling radiator with 2 140mm...
