I have found that the fans used in gambling machine cabinets are nice and quiet even at full pelt.
I have a Corsair 140mm fan in my home brew beer cooler and it is very quiet. Its 12V 100ma power supply shares its mains input with a heat pump that is no more noisy than a domestic fridge. The fan is hardly any louder than the pump motor.
If you can find any head room in your cabinet a bigger fan would be the way to go.
