Boxed Processor Specifications
The boxed processor's fan heatsink 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.
