Thermal and Mechanical Design Guidelines 

 41 

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. 

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.   

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
