I am in the process of building a new computer. The case I am using is a Fractal Design Core 1000. It comes with a 120mm fan in the front which sucks air in. It also has slots for a 92mm in the back and another 120mm on the side. My power supply (Corsair CX430M) also has a fan (looks like 120mm) which I assume sucks from the bottom and blows out the back.
I have a few issues. Firstly, I have the fans currently set where the front and side 120mm fans bring air in. The rear 92mm and the power supply fan suck out. Is this an optimal configuration?
Secondly, my motherboard (MSI FM2-A85XMA-E35) only has two sysfan head headers. What is the best way to get the third fan working? Should I use a Y splitter to get the third fan working or should I use a molex adapter? If only one fan is going to be plugged directly to and controlled by the motherboard should I make it the side mounted 120mm intake or the 92mm exhaust?
