Thermal Management Guide

The Intel® Joule™ compute module integrates a powerful four-core, 64-bit Intel® Atom™ SoC, high definition graphics, and wireless communications into a compact System on Module (SoM) form factor.
The module generates thermal energy (heat) relative to CPU and graphics workloads.
 The goal of thermal management is to control this energy and maintain a balance between performance and the capacity of the system to effectively dissipate heat.
Designing an effective thermal management solution begins by determining the power requirements of the system’s worst-case workload under real-world conditions.
Once the power requirements for the workload have been established, a passive and/or active heat dissipation solution can be designed that will allow a system to operate with maximum performance.
 In the event that a system is operated outside of the parameters of the original design, the module includes firmware controls that will ensure the module continues to operate within a safe temperature range.

Product and Performance Information


Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
