Hi guys, I am building a new pc & am having a case fan problem. All my case fans or 3 pin & my MB only has 4 pin. The 2 front case fans actually have an odd connector, it has 3 male & holes for 3, which means it is not staying hooked up to the MB. Id rather not have to replace all the fans. any1 have this issue? CASE - Corsair 500R MB - Gigabyte z77x-ud3h thanks!
