Chiming in here, since I'm looking for ovens and am considering Dacor, DCS, and Thermador in the 27". Everything is a tradeoff -- but I, too, want a quiet fan. My current exhaust fan on my upper oven OTR is a horror - it goes on by itself when I am using the upper oven and stays on forever. I only use that oven in emergencies, as a result. I have an old one-piece, 2 oven range that they don't make any more Thank goodness!

I've had my Dacor double wall ovens for 5 years. The fan is exceptionally quiet. You have to stand next to the appliance to even hear the faint whir and that's the same even if both ovens are on. I don't know what I'll do if I ever have to replace these. We have a large open kitchen with ceramic tile there nothing was done to add any extra sound deadening to the ovens.

I agree with Jakvis, different people have different sensitivities to noise. My GE Monogram French Door oven in my ipinion is very quiet. My husband who is very hard of hearing hears it when it is in the preheat mode. It is a low rumbling sound that is very loud to him and sounds like a barge coming by our house. When it cools I hear it I know it has to cool things and I hear in a vague sort of way it's clearly not excessive. Now ask me about my VentAHood which only has one speed ---LOUD- and LOUD Not sure when I bought that system if they had two speed.but it is screaming loud and I can't hear anyone talking to me. I do use the self clean function on the oven and expect it to run a fan to cool things.; It really isn't excessive and well worth for the cleaning experience that I don't have to get involved with ::)) So noise is acceptible to me in many c ases unlike cilantra which tastes like soap and makes me ill where other people find it frangrant and tasty. Life is interesting to be sure. Inga

I'm surprised because I had a 6 year old Bosch 800 oven in my condo and loved it. Yes the fan stayed on for a while after it was done cooking, but it wasn't overly loud. And I don't ever recall it blowing air. And if I recall, to increase the temp, all I had to do is hit the bake button (or whatever button I was using) and then hit the temperature I wanted again. I didn't have to turn it off first.
