Datasheet
Note:
The boxed processor’s TMA requires a constant +12 V supplied to pin 2 and does not
support variable voltage control or 3-pin PWM control.
The power header on the baseboard must be positioned to allow the TMA power cable
to reach it. The power header identification and location should be documented in the
platform documentation, or on the system board itself.
shows the location of
the fan power connector relative to the processor socket. The baseboard power header
should be positioned within 4.33 inches from the center of the processor socket.
NOTES:
1.
1.
Baseboard should pull this pin up to 5 V with a resistor.
2.
Open Drain Type, Pulse Width Modulated.
3.
Fan will have a pull-up resistor to 4.75 V, maximum 5.25 V
