Well, I heard for the first time that the fan is equipped with electric plug.Brother, do you know why the machine has fans?For computer accessories, take the CPU. As soon as your computer is turned on, the fan starts to run. You will find that the temperature of the CPU is about 50 degrees. That is to say, as soon as your computer is turned on, the CPU will be 50 degrees.Imagine that if your CPU is not pressed by a fan, your computer will become soot after 30s.I haven't tried hot plug fan, you can try it.
