There's been some bugs noticed with the Switch since it launched, but this one has to be the strangest, as seen in a YouTube video upload by user Shokio.
In the video, their Switch can be heard making very strange noises, which have been likened to a spaceship, and even prog rock. Basically, weird, repetitive sounds keep coming from the console, which definitely don't sound natural, and seem to vary in speed, severity, and volume.
Have you had this issue with your console?
