I will share my experience of replacing the fan in this power supply. Initially, I did everything as in this post and nothing happened, the fan did not spin either under load or when turned on. I later stumbled upon this comment and noticed that the Noctua green is connected to the yellow Corsair, and the Noctua yellow to the Corsair green, black to black, blue to blue. I swapped yellow with green and after that everything worked as it should. The fan rotates at startup and under load.
