Advanced Fan Control Features
 Advanced
Fan Control Uses Automatic Fan Speed Control
with Integrated Dynamic Tmin Adjustment
 Initialization with Operating Temperature Threshold Value
 Eliminates the Need for Extensive System Thermal
Evaluation to Determine Tmin Value
 Optimizes the Control Loop to Keep Fans Running at the
Lowest Possible Speed Irrespective of Thermal Changes Due
to System Configuration or Operating Conditions

Based Fan Speed Control
 As system load decreases,
power dissipation decreases,
temperature decreases, fan
speed decreases, acoustics
decrease
HOT SPOT
COOLING
 As system load increases, power
dissipation increases,
temperature increase, fans
speeds increase, acoustics
increases
 Closed Loop Control ensures
that you are operating at the
lowest possible acoustics, while
providing a safe operating
environment.
