I've had the dual fuel range since May. While there is a noise with the fan, IMO, it's not excessive. It usually shuts off within 5-8 minutes of turning the oven off. I don't use the oven as much as I use the stovetop, so perhaps that's why it doesn't bother me. I have to say that I am sensitive to background noise, especially because I have four kids so any extra noise just adds to the already increased volume level in my house put out by the kids. So yes, I do notice the fan (usually moreso right after it goes off). To me, it's like the compressor on my old fridge. I didn't really notice it while it was on, but when it turned off, I'd notice how quiet it was all of a sudden (same when my heat goes on and off).

The joy I get out of the function of my new range far exceeds the downside of the fan noise (didn't have automatic fan with my old electric range) but we all have different levels of comfort so I can't attest to whether it will be a problem for you. I read those reviews before getting mine but, to me, the fan noise has not been a problem. I also was able to hear what the fan sounded like before purchasing mine b/c my friend has the same range.

Hopefully it won't be an issue for you and you will enjoy your new range!
