Hello There, I have a question about my circuit as I don’t wanna burn my house down. Basically I bought a 5V 40A switch power supply. The fan I’m operating of it is a 12V, therefore, the fan spins too slow for my liking. However, I read that if you put the wires in series it will make I 10V. Will connecting + and - on my power supply not break it? The images are attached to this post, thank you in advance, Sylwester.
