70 Datasheet

Any motherboard components placed in the area beneath the fan heatsink supports must recognize

the clearance given in Table 38. Component height restrictions for passive heatsink support

designs, as described in AP-588, Mechanical and Assembly Technology for S.E.C. Cartridge

Processors (Order Number 243333), still apply.

Motherboards designed for use by system integrators should not have objects installed in the

heatsink support holes. Otherwise, removal instructions for objects preinstalled in the heatsink

support holes should be included in the motherboard documentation.

NOTE:

1. All dimensions are in inches. Unless otherwise specified, all dimensions with three significant digits have a tolerance of

±0.005 inches. All dimensions with two significant digits have a tolerance of ±0.01 inches.
