 - `CPU_TEMPERATURE_THRESHOLD` parameter is the T°junction (junction temperature) threshold beyond which the Dell fan mode defined in your BIOS will become active again (to protect the server hardware against overheat). **Default** value is 50(°C).
 - `CHECK_INTERVAL` parameter is the time (in seconds) between each temperature check and potential profile change. **Default** value is 60(s).
 - `DISABLE_THIRD_PARTY_PCIE_CARD_DELL_DEFAULT_COOLING_RESPONSE` parameter is a boolean that allows to disable third-party PCIe card Dell default cooling response. **Default** value is false.
+- `KEEP_THIRD_PARTY_PCIE_CARD_COOLING_RESPONSE_STATE_ON_EXIT` parameter is a boolean that allows to keep the third-party PCIe card Dell default cooling response state upon exit. **Default** value is false, so that it resets the third-party PCIe card Dell default cooling response to Dell default.
