Thermal/Mechanical Design Guide
Fan Speed Control: Thermal solution that includes a variable fan speed which is
driven by a PWM signal and uses the on-die thermal diode as a reference to change
the duty cycle of the PWM signal.
Constant from the processor datasheet that is added to the
T
results in the value for
CONTROL
Value read by the BIOS from a processor MSR and added to the
T
results in the value for
CONTROL
T is the specification limit for use with the on-die thermal diode.
CONTROL
Pulse width modulation is a method of controlling a variable speed fan. The enabled 4
wire fans use the PWM duty cycle % from the fan speed controller to modulate the fan
speed.
Any standalone or integrated component that is capable of reading the processor
temperature and providing the PWM signal to the 4 pin fan header.
Balanced Technology Extended: BTX is an enhanced form factor specification for
desktop platforms.
Thermal Module Assembly. The heatsink, fan and duct assembly for the BTX thermal
solution.
