No case fans

Hello. I have a new motherboard and the bitfenix prodigy case.

Im running the noctua nh-d14 heatsink which has 2 fans of its own + the 2 on the case.

There only seems to be one header on the board which I have a splitter in to run both noctua fans on the heatsink. However this means neither of the 2 case fans are on.

Im looking at getting a fan controller to go in the drive bay at the front of the case. Will this allow more fans to be connected if not is it dangerous to not have the case fans on as my GPU has its own fan plus the 2 big fans on the CPU heatsink?

Thanks

You could also use this to power more fans instead of a fan controller.

PWM splitters only work on PWM fans. Unless you want your 3-pin fans to run full speed all the time. The PSU supplies a constant 12v through splitter to fans while the motherboard receives RPM signal from one fan and supplies PWM signal to all fans. PWM fans have PCB that received the PWM signal and pulses the 12v power to fan to regulate it's speed.

I use PWM splitters or hubs with all PWM fans on all my builds now. Case fans speed up and idle same as CPU fans. But for variable voltage control Tealc is the man to go to.

He makes very nice custom PWM to analog adapters. PWM control from motherboard, power from PSU, and variable voltage to fans. One of his PWM to analog adapters will control all four of your 3-pin fans with ease.
