What sup guys. Im going to set up my push and pull system. i have only 1 cpu_fan connector in my motherboard so i ordered splitter as well. before i setup push and pull i need to ask. will my motherboard cpu_fan connector in motherboard will handle 2 corsair air series pwm high performance edition fans. my motherboard is gigabyte 990fxa ud3 and i have amd fx8350 and corsair h60 2013 edition liquid cooler. Im not sure or my motherboard cpu_fan socket has enough voltage to handle 2 of these fans, if anyone know please let me know. i want to be safe.

Motherboard CPU FAN headers can usually handle 2 fans safely. I presume you ordered a PWM 4 wire splitter similar to this:

You'll notice one of the female connectors has the tach feedback pin missing. That is so the BIOS doesn't get confused with 2 feedbacks.

It's not the voltage that is the concern, it is the amperage (current) that the 2 fans will draw. The voltage will remain at +12V. But you should be OK.
