Need some help with fan header setup

[sheen.li.0401]

OK, so here is my dilemma.

I have a Z370 TUF Gaming Plus mobo:

I have 4 fans. One comes with the case (Phanteks P300), three of them has these connectors:

The CPU fan has two headers, one 4 pin and one 3 pin:

What I'm doing is connect the 4-pin CPU fan to the CPU header, and the 3 pin to the AIO header.

Then, the default fan plugged ito CHA_FAN2, while the 3 I bought daisy-chained using the molex connectors to 1 header (CHA_FAN1).

The problem now is that the header does not provide enough power for the 3 fans, making the LED blink every few seconds.

So I connected the daisy-chained fans to a molex from the PSU.

The problem now is the fans are always running at full speed.

Any suggestions on how get the best out of this setup?

Pick up a PWM fan splitter like this one and you should be able to hook up all your case fans off one header like the CPU_Fan header.

Hi Lutfij,

Thanks for the suggestion. Will the header be able to power all fans? I actually daisy chained three fans using the molex connector to one header and the lights started blinking, which means that it isn't getting enough power. I'm afraid this will happen too even using a splitter?

Ok nevermind, I realized that the splitter comes with a molex for power, thanks, I'll check the item out!
