ATX KOZ 3-D Model Primary (Top) Side

Note: All Maximum Component Heights are post reflow / assembly
Note: The maximum height of the reference thermal solution (in
motherboard is 46.00 mm [1.81 inches], and is compliant with the motherboard
primary side height constraints defined in the ATX Specification and the microATX
Motherboard Interface Specification found at http://www.formfactors.org.
The reference solution requires a chassis obstruction height of at least 81.30 mm
[3.20 inches], measured from the top of the motherboard. This allows for appropriate
fan inlet airflow to ensure fan performance, and therefore overall cooling solution
performance. This is compliant with the recommendations found in both ATX
Specification and microATX Motherboard Interface Specification documents.
