Main Control PCB Assembly
The fan-drive circuit on the main PCB utilizes a thermal sensor and a switching transistor to manage heat dissipation. A constant-run symptom indicates that the thermal regulation logic has been bypassed, likely due to a shorted switching MOSFET or a failed NTC thermistor that is incorrectly reporting temperatures exceeding the 104°F threshold to the CPU.
