You can use a 4pins fan splitter to connect 2/3 PWM fans to a single header. You do not want to use more than 2/3 fans on the same header using a non-powered splitter (depends on the how much current the header can provide and how much amps your fans draw).Another solution would be to use a dedicated fan controller / fan hub.It's a small box that connects to a PWM header of your motherboard, takes power from your power supply (often using a SATA power or MOLEX conenctor) and provides several PWM connectors for your fans. As it uses an external source of power instead of what's provided by the motherboars header, you can connect way more fans.
