6.1.5 Processor Specification for Operation Where Digital
Thermal Sensor Exceeds T
When the DTS value is less than T
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
algorithm must drive the fan speed to meet or exceed the target thermal solution
performance (

i5-2000 desktop processor series (Quad Core 65W) and Intel

processor 800 and 600 series (Dual Core 65W),
desktop processor series (Quad Core 45W) and
and i3-2000 desktop processor series (Dual Core 35W) . To get the full acoustic benefit
of the DTS specification, ambient temperature monitoring is necessary. See
for details on characterizing the fan speed to 
