A few thoughts:
Scope out the path of air flow. You need an air in and an air out and see to it there is a path and the air after it picks up the heat won't be heating something you don't want it to.
When it comes to fans bigger is quieter for a given CFM.
If you use something like the LM317, you could incorporate a thermistor in place of the fixed resistor or adjustment pot, locate it in the hot spot and you will have a demand throttling fan which will adjust it's speed as needed. You will have to spec out the value for the thermistor.
