Hey,
I am going to get the NZXT Phantom410 which has re-installed fans, a molex plug and 3-pin fan headers are included.
The motherboard (Asus Crosshair V formula-Z) however has 4-pin chassis fan connector. Is it still compatible or not?
3-pin fans can be used in 4-pin headers; The 3 pins on those are the same. The fourth pin on the 4-pin header is for controlling the speed of PWM fans.
