Thermal Management
5.4.4 Thermal Metrology
The maximum TTV case temperatures (T
CASE-MAX
) can be derived from the data in the
appropriate TTV thermal profile earlier in this chapter. The TTV T
CASE
is measured at the
geometric top center of the TTV integrated heat spreader (IHS). Figure 5-5 illustrates
the location where T
CASE
temperature measurements should be made.
The following supplier can machine the groove and attach a thermocouple to the IHS.
The following supplier is listed as a convenience to Intel's general customers and may
be subject to change without notice. THERM-X OF CALIFORNIA, 3200 Investment Blvd,
Hayward, Ca 94544. George Landis [phone] Ext. 368 [e-mail].
The vendor part number is XTMS1565.
5.4.5 Fan Speed Control Scheme with Digital Thermal Sensor
(DTS) 1.1
To correctly use DTS 1.1, the designer must first select a worst case scenario T
AMBIENT
,
and ensure that the Fan Speed Control (FSC) can provide a Ψ
CA
that is equivalent or
greater than the Ψ
CA
specification.
The DTS 1.1 implementation consists of two points: a Ψ
CA
at T
CONTROL
and a Ψ
CA
at
DTS = -1.
