spike smoothing). Please select the lowest setting available close to 4.0 seconds by the
fan speed control device
4. The Fan Speed Controller, or Health Monitor Component, takes the result of the two fan
speed ramps (processor and system) and drives the TMA fan to the highest resulting
PWM duty cycle (%)
5. For BTX systems a second thermal sensor is recommended to capture chassis ambient
for more detail see
Appendix F.
6. To ensure compliance with the thermal specification, thermal profile and usage of the
T
SENSOR
for fan speed control these setting should not be user configurable.
7. If this function is present on the device it must be enabled
Note: The fan speed component vendors provide libraries that are used by the BIOS writer
to program the component registers with the parameters listed above. Consult the
appropriate vendor datasheet for detailed information on programming their
component.
