1 - i can hear any fan, even the wonderful Papst 4412 N/2GL, undervolted. I'm not bionic, i'm even a heavy metal addict (read, damaged ears). A fan is never silent, unless it's turned off.
2 - adding a fan in a system where your primary goal is to *suppress* every source of noise and fan... is to throw your goals to the bin
3 - a heater core has densely packed fins, usually 1mm to 2mm across. This is not suitable for passive convection cooling. Try any onlince calculator, for optimal (and working) convection you'll end up with fins spaced about 5mm (at least), provided you're using fins about 20mm long, placed vertically of course.
4 - Size matters
