 ## Troubleshooting
 
-If your server frequently switches back to the default Dell fan mode:
+### Your server frequently switches back to the default Dell fan mode:
 1. Check `Tcase` (case temperature) of your CPU on Intel Ark website and then set `CPU_TEMPERATURE_THRESHOLD` to a slightly lower value. Example with my CPUs ([Intel Xeon E5-2630L v2](https://www.intel.com/content/www/us/en/products/sku/75791/intel-xeon-processor-e52630l-v2-15m-cache-2-40-ghz/specifications.html)) : Tcase = 63°C, I set `CPU_TEMPERATURE_THRESHOLD` to 60(°C).
 2. If it's already good, adapt your `FAN_SPEED` value to increase the airflow and thus further decrease the temperature of your CPU(s)
 3. If neither increasing the fan speed nor increasing the threshold solves your problem, then it may be time to replace your thermal paste
