Z170M Pro4s fan header power

[bcobler]

I asked ASRock how much power each fan header can put out, this is what they said.

motherboard support 12 volts dc , 1 amp maximum , 12 watts per pin out header.
I have 6 case fans at all and they are Bitfenix Spectre pro 140mm fans. 2 in the front, 2 up top, 1 in the back, and a be quiet cooler on the back.
Each fan except the CPU cooler draws 12v each, I dont know how many I could put in if each header supports 12w. The CPU cooler is a be quiet cooler. My power supply is a evga 600W also.

The spec for those fans says ~0.2A. So in theory you could run 5 on one header, but I wouldn't because the fan startup current is probably higher. Running 3 fans per header should be ok though.

So just to make sure, you used these to figure that out right?

Also the fan connector are 3 pins I think for the splitters. I'm pretty sure It can support 4 pins

Yes. I looked here: https://www.bitfenix.com/global/en/products/accessories/spectre-pro#specs
As you can see, the model number for the 140mm fans match the model number from the amazon page.

Yes, the fans don't seem to be PWM so they would be 3 pin. You can plug a 3 pin fan into a 4 pin header/splitter.
