Fan Oven Views
I've got the Frigidaire oven where you can turn the convection on and off. That's what the model you posted does. The convection is virtually soundless. The only way you hear it, is if you're standing right next to the oven, almost bending down next to it. It does not run after you turn the oven off, it stops immediately. The fan starts (and runs) only when you've selected to use convection option.Hope this helps.
We recently got the LG true convection oven. Its great!!! I absolutely love having it. On mine you can either use it like a "normalr" oven, or the convection. The fan really isnt loud at all. I barely notice it. It also only runs when I am using the convection setting. In all honesty the vent fan above the stove is 10X's louder than the oven is. I think that it is definetly worth getting, you will love having it. Makes cooking so much quicker.
Convection ovens or fan ovens or turbo ovens augment a traditional oven by circulating heated air using a fan. The fan motor is in a separate enclosure, to protect it from overheating and melting any plastic components including wire insulation. Food warms faster in a convection oven, because the moving air strips away the thin layer of air which otherwise would surround and insulate the food. This is the same physical phenomenon which causes wind chill.
Although the word convection is usually used to describe the natural circulation of gas or liquid caused by temperature differences, the convection in convection oven has a more general definition: the transfer of heat via movement of gas or liquid. In a regular oven, convection occurs due to the temperature difference between air near the heating element and the cooler air near the food being warmed. A regular oven relies on a combination of radiation from the walls and, to a lesser extent, air convection to heat the food. Convection ovens impart more convective heat than regular ovens by using fans to force air movement.[1]
