Fan Power Recommendations for Auxiliary Fan
To facilitate power to the auxiliary fan and provide fan monitoring, a fan-sense capable power
header may be provided on the baseboard near every processor that may need an auxiliary fan.
Although the boxed processor does not ship with an auxiliary fan, it is highly recommended that a
power header be provided. It is also recommended that the power header be consistent with the
power header for other boxed processors that feature a fan-sense capable fan heatsink.
