What Should I Do

[luckychalmz]

Okay I am finalizing my build, I have had a speed bump. I was using a fan controller, but in recent decisions I have decided not to use it. So now I am curious to know rather I should connect my fans with a molex connector to each one or just connect one and connect them with the one that is attached to the connected fan and just keep connecting them all like that; or a molex from the power supply to each one.

Not sure I correctly follow you here.

You can splice all your fan leads into 1 and use a single molex if you want...this is what I did. However, DO NOT splice multiple fans into a 3 or 4 pin and then run to a MB header. A power supply can handle the load of multiple fans drawing on a single molex; I wouldn't take the chance on a MB header.

You followed me correctly, lol. Another thing, I have a Noctua NH-D14 and it comes with one of those 3 pin splice connectors. So you can put two in one. When I was installing it I plugged that connector in a 3 pin connector that was on the motherboard right by the CPU and my fans wouldn't power up, and I got a CPU fan error when I powered my computer up. So I then plugged in my fans in these 4 pin connectors on the motherboard that were label CPU_FAN and PWR_FAN and they powered right up. I got a CPU fan error when I had it plugged in the other one. Is the way I have this setup correct?

Yeah, but you can turn that off in the BIOS; if you run watercooling, you'd want to be OFF due to there not being a CPU fan installed.

I don't run water cooling. So the way I have these installed on the motherboard is correct? Because the connecters for the fans are 3 pin and the ones on the motherboard are 4 pin.

I know, it was just an example.

They are the same, you will be fine. You can run 4-pin on 3-pins as long as the pins match up correctly.

Haha sorry my mistake. Thank you for your help, appreciate it sir!

I'm not an expert, but I've had fans like this before and they've had a tab that allowed the correct 3-pin connection.

Here is an example
