TheBaron had this to say if you can get more than 60cfm on less than 40db lemme know, cause i want one too. the panaflo's might be close
Black Hawk had this to say The Thermoflow TF-9225 and Thermaltake TT-9025 look nice.

Here's the best I've found so far... but it doesn't have 4 pin power AND 3 pin RPM, just a convertor...
SVC - Enermax
Neither one of those beats that Enermax tho... In fact, neither one of those really beats out the 53CFM Mechatronics fan I've got right now...
The 92mm Panaflo U1A comes in with 69 CFM @ 43 dBA.
Both can use either the 4-pin molex or 3-pin fan-header, but do not offer RPM monitoring.
Not sure on US price ($27.00 CDN a piece).
