Thermal Specifications
6.1.6 Processor Specification for Operation Where Digital
Thermal Sensor Exceeds T
CONTROL
During operation, when the DTS value is greater than T
CONTROL
, the fan speed control
algorithm must drive the fan speed to meet or exceed the target thermal solution
performance (Ψ

To get the full acoustic benefit of the DTS specification, ambient temperature
monitoring is necessary.
