Processor Specification for Operation Where Digital
Thermal Sensor Exceeds T
CONTROL
When the DTS value is less than T
CONTROL
the fan speed control algorithm can reduce
the speed of the thermal solution fan. This remains the same as with the previous
guidance for fan speed 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 (

) shown in
for the Intel
®
Core™ i7-3960X, i7-3970X
processor Extreme Edition, Intel
Core™ i7-3930K processor, and Intel
®
Core™ i7-
3820 processor. To get the full acoustic benefit of the DTS specification, ambient
temperature monitoring is necessary.
