Toms Hardware posted retraction over a year later admitting motherboard was at fault and test was proposed and designed by Intel (including picking motherboard vendors) as part of their Pentium 4 promotion drive.

Same as Pentium 3 of same era, thermal throttling on socket A was supposed to be implemented by Motherboard vendors using chip integrated thermal diode. Pentium 3 would burn same way if put on a motherboard with non working thermal cutout.

TBirds and spitfire didn't have die sensor, that was first on Palomino/Morgan.

That said I've seen P4s die due to cooler failure so it was still dumb.

This is from that Toms article:

"Just like AMD's mobile Athlon4 processors, AthlonMP is based on AMD's new 'Palomino'-core, which will also be used in the upcoming AthlonXP processor. This core comes equipped with a thermal diode that is required for Mobile Athlon4's clock throttling abilities. Unfortunately Palomino is still lacking a proper on-die thermal protection logic. A motherboard that doesn't read the thermal diode is unable to protect the new Athlon processor from a heat death. We used a specific Palomino motherboard, Siemens' D1289 with VIA's KT266 chipset."

Intel suggested Siemens D1289 board for the test, board didnt have thermal protection. Intel suggested (or even delivered) Pentium III motherboard with working thermal protection.
