1. If temperature reading from the MAC or CPU, the APIs will return a fallback value that causes the fan to operate at 100% speed. Default to reading MAC temperature from SDK; if it fails, fall back to FPGA reading and apply a +5°C offset for compensation. 2. If the BMC supports thermal policy, the system reports temperature readings to the BMC at 10-second intervals. 3. If the BMC becomes unresponsive or fails, thermal control falls back to CPU-based monitoring 4. Update the transceiver temperature threshold from 75°C to 70°C. 5. Refactored to modular class-based architecture with dual BMC/CPU thermal control paths.
