I'd like to buy the new Kuhler 920 but there is one thing I need to understand before I do that. I plan to replace the standard fans with some ultra-quiet fans. This raises two questions:
1) can I connect them to my fan controller? will the Kuhler refuse to start?
2) if I must connect them to the Kuhler, do they have to be PWM?
2) Yes (to get fan control via the software, I am not sure if they will start or not though)
