When I recently upgraded I went to a new Corsair C70 case with larger fan mounts, switching my old cheap 80mm's (only 3) to 120mm (now 6 Corsair AF120). With the higher quality fans, the pc is now virtually silent when operating on typical loads as it drops the rpms to bare minimum. The odd hard drive click is all I hear. I used to hate the sound of my jet engine style cooling on my old case and extremely pleased on how this turned out.
When I'm playing games the fans do ramp up and can be heard again, but still isn't bad and since your wife doesn't use the pc to play games, that won't be a problem.
IMO, water cooling won't necessarily net you even more decibal savings especially considering the cost.
