You're probably hearing the cooling fan that runs air over the control board to prevent it from over heating. This will stay on for a bit of time even after the oven is turned off.
There could be a few reasons why your oven is making noise even when it is turned off. One common reason is that the cooling fan or the convection fan may still be running to cool down the oven after use. Another possibility is that there may be a problem with the oven's heating element or other internal components causing the noise. It is recommended to have a professional technician inspect and repair the oven to determine the exact cause of the noise.
The time it takes for an oven to cool down after being turned off can vary, but typically it can take anywhere from 30 minutes to a few hours, depending on the type of oven and how hot it was when turned off.
Only if the oven is turned off.

There is a heat sensor that allows the fan to stay on after the key is off to cool down the underhood temperatures. If the fan stays on as you have said, the sensor is most likely faulty or shorted.
Blower fan relay is stuck or fused contacts, replace it
If there was no feedback in an oven system, it would keep getting hotter until it melted, exploded, or was turned off.
