Help: Not enough fan headers on Gigabyte GA Z170N-Gaming 5

[NubaBuilder]

Hello, I have a Gigabyte GA Z170N Gaming 5, and it only comes with one CPU fan header and one System Fan Header. They are both 4 pin fan headers. When I plug in my CPU Coolor (Corsair H105), it uses the CPU fan for the pump, and the System Fan is connected to the two Fans on the radiator using a Y connect. This means all my Fan Headers are used.

So I have the Radiator in the Front, and the Fans blowing into the case past the Radiator, but I have no other Fans left. It's a Corsair mini itx 240 case. Do you think I need another Fan to evacuate the hot air or is the two fans in the radiator enough?

If I need more Fans, whats the recommended way of doing it? Should I get a PWM header and plug it into the System Fan Header on the Motherboard, then the other Fans into the PWN header? I've never used a PWM header before.

Thanks.

Fan Mount Locations:
Front: 2 x 120mm.
Top: 2 x 120mm.
Bottom: 2 x 120mm.
Rear: 2 x 80mm.
Side: 1 x 120mm .

You can use straight DC current fans and connect them to power supply.

If you want PWM fans I suggest a hub.
