I attached the exhaust fan to the MOBO, the mobo is definetly slowing it down. The air being pushed out is nowhere near what it was when it was connected to just the PSU.
As you can see, Fan in 0 is running at max, which is the 3pin for the CPU. The fan in 1 on other hand, is running at it's lowest RPM. The mother board is taking control over the psu in this case.. strange. It was blowing almost double when it was only hooked up to psu.
