For what it's worth, I built a camera cooler using a Peltier TEC as the cooling element, and a fan-forced heat-pipe CPU cooler as the heat sink. If I run the fan at 6V instead of 12V, it runs at about half speed (I guess), but more importantly, it runs much more quietly and with a LOT less vibration, while still easily getting the heat away from the TEC.
