Hi Alex, you can connect any fan you want as long as it has a 4PIN PWM connector. I was also able to connect 3PIN fans, but then you can only control them via the voltage, which is somewhat less precise than with a 4PIN PWM fan. But no matter which fan you connect, 3PIN or 4PIN, they all show up in the NZXT software and you can control them there. In short: Yes, you can also connect the fans from the NZXT H510.

Greetings, Elias.
