What is the wires with the black tip on the thermistor fan?

This is the thermistor, which is an electronic component that adjusts resistance according to its temperature. As the black tip heats up, the fan should speed up accordingly. Place the thermistor as close to your heat source as possible so the fan can regulate its speed based on the temperature of the component. Do not cut it off, the thermistor fans are not designed to work without the thermistor probe.
