if the motherboard is designed for the case fan you are using its best to plug it into the motherboard, this will free up a spot on the power supply. Otherwise as long as the voltage and amps are the same it doesn't really matter.
If you try to plug it into both you will double the power of the fan and very likely fry the fan.
The motherboard does not connect the power supply to the peripherals. The power is supplied directly to most peripherals such as HDDs and CD drives by cables from the power supply. Some special expansion cards, such as network cards, get enough power from the motherboard through the PCI slot to function.

The atx 12 connector is one of the motherboard power connectors and used for 12 volt power connect for cpu voltage regulator.
Connect Pin No. 14 & 15 on SMPS, if the fan moves then SMPS is working fine else SMPS is faulty.
You should not bother to check any power supply in the motherboard. You need to take the motherboard to service centre if faulty.
