Attention!

Intel designed this thermal solution to ensure adequate cooling of your boxed Intel

Pentium

4 processor in the 478-pin package. The thermal solution also provides

increased shock and vibration protection during normal shipping and handling of assembled

systems. To accomplish this, the thermal solution provides controlled compression on the

processor and socket. This compression results in curvature in the motherboard.

Therefore, to ensure proper installation and maximum reliability:

• Intel recommends that system integrators select only chassis with a minimum clearance

of 0.250” [6.35mm] between the underside of the motherboard and the bottom of the

chassis in order to guard against contact between the motherboard and the chassis.

• Do not use additional board stiffening devices (typically installed underneath the

motherboard) with this thermal solution. Stiffening devices may significantly increase the

compression and cause permanent damage to the processor or the board.
