2.2.7.1 Dual Thermal Profile Concept for the
X5300 Series
The Quad-Core Intel® Xeon® Processor X5300 Series is designed to go into various
form factors, including the volumetrically constrained 1U and custom blade form
factors. Due to certain limitations of such form factors (i.e. airflow, thermal solution
height), it is very challenging to meet the thermal requirements of the processor. To
mitigate these form factor constraints, Intel has developed a dual Thermal Profile
specification, shown in
