Acoustics
[Performance] - Fan control provides primary system
cooling before attempting to throttle memory.
[Acoustic] - The system will favor using throttling of
memory over boosting fans to cool the system if
thermal thresholds are met.
This option is hidden
if CLTT is enabled.

The Security screen allows the user to enable and set the user and administrative password.
This is done to lock out the front panel buttons so they cannot be used. This screen also allows
the user to enable and activate the Trusted Platform Module (TPM) security settings.
