[QUOTE="DanielSydnes, post: 1391472, member: 246925"] Actually that is incorrect. Nearly all Intel processors have thermal protection. This includes a temperature sensor built into the processor die as well as thermal throttling and thermal shutdown. If a processor overheats (over its Tcase specification), it will lower its clock rate then halt. Engineers cannot anticipate every environment nor every possible failure mode. For example, MacBook Pro laptops placed on a soft, deformable surface like a couch or futon will overheat because the heatsink vents on the back near the screen hinge can become blocked. Ditto with dust, grime, pet hair, tobacco smoke, etc. Manufacturing defects are a possibility. Consider the failures of adhesive thermal compound pads in numerous laptop brands. Or the lithium ion battery fires caused by metal contamination during assembly. Or the capacitor plague caused by bad electrolyte recipes. Bottom line, mistakes happen even in the best engineering teams and manufacturing facilities. That said, the most likely causes of this symptom are: [B]Run away process.[/B] Use Activity Monitor or similar program to see if any program or service is using a large percentage of processor time or hard drive activity.
