For 80mm case fans I like the Sunon 39cfm/32dBa. Cheap fan, and very quiet for the cfm. The Panaflo high is also 39/32, but costs more and also has bare connectors in stock form so add ATX/molex connectors to the price and hassle. Also IMO the Sunon is lower frequency so sounds "quieter" to the human ear, even though they're rated the same dBa.
39/32 is sort of the sweet spot for good airflow. If you want higher cfm the dBa increases a lot after this point; conversely if you want lower dBa the cfm drops a lot. But again it depends if you need the cfm or not, you might be better off with lower airflow fans if you don't want as much noise. Of course you could also get a rheo.
