Datasheet
The boxed processor's fanheat sink 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 fan heatsink 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 110 mm [4.33 inches] from the center of the
processor socket.
