Determining and setting the thermal mode for an 8335-GTG, 8335-GTH, or
8335-GTX system
Learn how to determine and set the thermal mode that is required for your system.
You might be required to set the thermal mode of the system to a setting other than the default setting,
depending on your system, adapter, and cable type. Failure to set the correct thermal mode might result
in system errors. To determine the thermal mode that is required for your system, see the following tables
depending on the system model, adapter, and cable type that you are using. For instructions about setting
the thermal mode, see Setting the thermal mode.
Notes:
• If your system has more than one of the adapters and cable configurations that are listed in the table,
select the thermal mode for the adapter and cable configuration that has the highest fan speed, where
the order of fan speed from slowest to fastest is DEFAULT, CUSTOM, HEAVY_IO, and
MAX_BASE_FAN_FLOOR.
• After a factory reset of the system, the thermal mode setting is lost and must be reapplied.
