If the FG signal is unstable, is there any possibility of the cooling fan showing "fluctuations"?

What is the FG signal?
The FG signal is a pulse signal output by the Hall element or photoelectric sensor inside the cooling fan. Its frequency is directly proportional to the Fan speed. The system monitors the fan speed through the FG signal to achieve fault early warning and intelligent control.

Conclusion
The FG signal is like the "pulse" of the Cooling Fan. The stability of the signal directly affects the fan's speed control and the equipment's heat dissipation efficiency. An unstable FG signal can indeed cause "fluctuations" in the fan's operation, affecting the normal heat dissipation of the equipment and even triggering system alarms or shutdowns. By choosing high-quality brand fans, strengthening installation and commissioning, and controlling the environment, the problem of FG signal fluctuations can be effectively avoided, ensuring the long-term stable operation ofthe cooling fan.
