Connectors/Case Fans

[Dovydas S]

Hi everyone, I just got 2 new Noctua fans, specifically the NF-A12x25 PWM Premium Fans and I'm trying to get them working using the y-cable provided by noctua and connecting them into 1 fan header slot, but only 1 fan gets power. These are also gonna be used as exhaust fans. I'm also trying to figure out what kind of fan connectors this is. I have attached a picture for reference. One of those 4 pin connectors powered my previous exhaust fan. By the looks of it, it's also connected directly to the power supply and to the hard drive too. So I'm pretty much lost on where to get started. I'm also now hearing a second beep after the pc boots up. It does its regular beep and then 1 beep a few seconds after. 

 

Thanks for the help.

I deally get something like this and split the 4 pin fan header connection from your motherboard.
If you connect directly to a molex power connector it will run at full 12v speed all the time, you dont need that much airflow and all it will do is attract more dust.

And where would the fan spillter plug into?
