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.

Figure 7-43 through Figure 7-47 in Appendix G provides the motherboard keep-out
information for the BTX thermal mechanical solutions. Additional information on BTX
design considerations can be found in the Balanced Technology Extended (BTX)
System Design Guide available atThe maximum height of the TMA above the motherboard is 60.60 mm [2.386 inches],
for compliance with the motherboard primary side height constraints defined in the
BTX Interface Specification for Zone A, found at
