Thermal/Mechanical Specifications and Design Guidelines
Notes:
1.
The ambient temperature is measured at the inlet to the processor thermal solution
2.
This column can be expressed as a function of T
AMBIENT
by the following equation:
CA
= 0.29 + (45.1 - T
AMBIENT
) x 0.0181
3.
This column can be expressed as a function of T
AMBIENT
by the following equation:
CA
= 0.29 + (45.1 - T
AMBIENT
) x 0.0105
4.
This table is provided as a reference please consult the product specification for current values.
5.
Based on the testing performed a curve was fit to the data in the form
Psi_ca = a x RPM
3
+b x RPM
2
+c x RPM + d, where:
a = -1.53 E-11, b = 1.41 E-07, c = -0.00048, d = 0.925782
6.
Full Speed of 3150 RPM the DHA-A thermal solution delivers a
CA
= 0.335 °C /W based on preliminary
testing.
7.
Minimum speed is limited to 1000 RPM to ensure cooling of other system components
