Spy Drone Propeller Makes For A Quiet PC - Hackaday

MIT recently announced its research on toroidal propellers to create quieter drones.

The obvious solution was to adapt the toroidal shape for a PC fan.

The shape of the blades on the MIT drones is visible in video and pictures, but there were no available 3D models.

Watching the comparison with a conventional fan using smoke was pretty impressive.

And, as [Major] points out, flying a drone is a different job than cooling a PC, so these tests don’t really negate the idea that the design may lead to quieter drones.
