Toroidal cooling fan 80mm propeler Disamble te fan (there are tutorial on Youtube) I broke the blades and used the center piece to put the new propeler over. It is ok. It works fine. I´m not sure about the noise, seems to be less than before, but I don´t have the correct equipment to measure. Included new version with 5 blades - best results.
