If there's sufficient intake CFM or adequate intake fans, I'd recommend the 212 EVO. If you want to spend cumulatively double the EVO's price, investigate something like a Noctua iPPC 120mm fan. The come in 3,000 RPM and 2000 RPM flavors.
Nor would I dissuade you from taking a "walk on the wild side" with the 3000 RPM version -- others might offer some discouragement.
But the key to your noise problem also derives from effective use of motherboard thermal-fan-control. Add another $10 to your "project," and you can control several fans from the CPU_FAN header while powering them directly from the PSU. The gadget is a PWM splitter called the Swiftech 8W-PWM-SPL-SAT or ST -- check at Performance PC's and Frozen CPU. Here it is:

The other item you might want to consider is the ThermalRight blue-rubber accordion duct:

These are designed to fit a certain ThermalRight heatpipe tower, but they work fine with similar towers of different manufacture, including the EVO.
The basic idea of it: You could almost abjure using ANY fan on the heatpipe tower itself if you had a reasonably quiet fan at the rear exhaust port with reasonably useful airflow potential (minimum 80 CFM to 100, 110 or higher).
Just in passing, almost beyond your requirement for information, I could tell you that you might suffer the necessary tedium with a $4 purchase of black foam-art-board (or any color, really), the appropriate glue, an Xacto knife, and an $8 package of Spire acoustic foam-rubber pads. You would build the duct box to fit snugly between the exhaust fan and the heatpipe-tower; then -- with attention to measuring the limits of your case for it -- wrap the box with the adhesive Spire material cut to size. If the box is designed for just the right interior dimensions, you could add a layer of the foam-rubber to the interior.
After that, you could even consider finding a 4,200 RPM Gentle-Typhoon AP30 PWM fan. That's a REAL walk on the wild side, but motherboard thermal fan-control, the effective ducting and acoustic enhancement would make that fan seem as tame as Sheri Lewis and Lamb Chop.
As to the motherboard/BIOS/proprietary-software fan control, you should find the solution for your motherboard by doing the homework.
PS -- a pretty good fan:

You might want to look at these -- a little bit limp in the airflow for my taste, but sufficient. The Cougar Vortex also reminds me to tell you that you should secure all the fans in your chassis with rubber fan mounts to isolate the vibration from case metal. Here's a whole pile of options:
