System Thermal/Mechanical Design Information
Thermal and Mechanical Design Guidelines 41
4.4 Safety Requirements
Heatsink and attachment assemblies shall be consistent with the manufacture of units
that meet the safety standards:
• UL Recognition-approved for flammability at the system level. All mechanical and
thermal enabling components must be a minimum UL94V-2 approved.
• CSA Certification. All mechanical and thermal enabling components must have
CSA certification.
• All components (in particular the heatsink fins) must meet the test requirements
of UL1439 for sharp edges.
• If the International Accessibility Probe specified in IEC 950 can access the moving
parts of the fan, consider adding safety feature so that there is no risk of personal
injury.
4.5 Reference Attach Mechanism
4.5.1 Structural Design Strategy
Structural design strategy for the Intel reference thermal solution is to minimize
upward board deflection during shock.
The design uses a high clip stiffness that resists local board curvature under the
heatsink, and minimizes, in particular, upward board deflection.
4.5.2 Mechanical Interface to the Reference Attach Mechanism
The attach mechanism component (E21952-001) from the Intel Boxed Processor
thermal solution can be used by other 3 rd party cooling solutions. The attach
mechanism consists of:
• A metal clip that interfaces with the heatsink, see Figure 22 for the component
drawings.
• Heatsink/fan mass ≤ 62 g
