2.4.8 Boxed Active Thermal Solution for the Dual-Core Intel
Xeon Processor 5100 Series
Intel will provide a 2U passive and a 1U passive / active heatsink solution for the boxed
Dual-Core Intel Xeon Processor 5100 Series. This active heatsink solution is primarily
designed to be used in a pedestal chassis where sufficient air inlet space is present and
side directional airflow is not an issue. This active heatsink solution consists of a 4 wire
PWM fan and a 1U passive heatsink compatible with 1U form factors both mechanically
and thermally. These solutions are intended for system integrators who build systems
