Custom Built PC : Question about Pump and Fan Power Locations

[benstyles999]

After trying to configure my fans as they are a bit loud, I noticed my pc has a few odd choices with where the fans and pump are connected. Is any of these an issue or should I just trust the people who put this together?

Front fan connected to the power supply - Leading to not being about to configure fan speed.
CPU Watercooler pump connected to CPU Fan 1 (Wouldn't want the motherboard to think it's a fan do I?)
CPU Radiator Fan (Back fan) plugged into System fan 4.

Is it a 120mm cooler? It seems like everything is fun though.
