Entertaining excerpts from sharkyextreme.com & later. On the case side, ATX 2.03 specifies four new screw holes on the motherboard tray. These screw holes are needed to mount four screw-in supports that lie under the Pentium 4 processor. These four supports are to hold up the reference Pentium 4 heat sink, which we will talk more about later in the article. There are no cases we know of available today that meet the ATX 2.03 specifications, so we suggest you hold off on buying that $200 super cooling case if you think you might ever get a Pentium 4. Don't fret though, we do expect that you will be able to manually drill the four holes into an old case in order to mount a Pentium 4 without having to buy a whole new case. . . . On the heat sink side, Intel has designed a monster 450g (about one pound) heat sink with a copper base and aluminum fins. This bad-boy feels more than twice as heavy as any socket heat sink we've seen other than what ships with Apple's G4s. This heat sink is designed to provide enough cooling for a Pentium 4 in a case with about 40CFM of airflow. An 80mm fan plus a power supply fan are usually enough to provide this much flow. The copper is necessary to deal with the increased thermal density of the Pentium 4 over previous Intel processors. The move to a .13 micron process will make cooling even more difficult. Looks like the brick-like heatsinks that come with the gigamine are the wave of the future. What did Paul used to say about not needing a fan? I think that was before my time. Cheers, Dan.
