Spy Drone Propeller Makes for a Quite PC - Hackaday

Recommended Posts

MIT recently announced its research on toroidal propellers to create quieter drones. That got [Major Hardware] thinking about noisy PC fans. The obvious solution was to adapt the toroidal shape for a PC fan. He was familiar with the idea from similar screws on boats that are commercially available...

 

The fan appeared to work pretty well, but the stock fan worked better. Oddly, the stock fan was also a little quieter overall, but the MIT-inspired blade was quieter at high frequencies. Static pressures were a good bit less for the new design.

When compared to the Noctua A12x25 it moved about half the air volume, but considering it's a 1'st attempt prototype compared to THE pc fan, it would be interesting to see how this does with a bit more refinement.  Sadly Major Hardware is unlike to sink more time into this.

This is really interesting i wonder what the static pressure would be.

Note i added a tag to your thread 🙂
