If I recall they also lacked any type of thermal management which all modern cpus have. So instead of the cpu throttling when it got too hot it would just BSOD or die. Even with constant high temperatures it's still extremely difficult to "break" a modern cpu.
That might explain why I had an AMD Athlon die. I recall smelling an very distinct metallic melting odor, then I go to find out that the CPU got fried. I never went with AMD since, Intel I never had a single issue with and I'm glad I have one to use for Dolphin.
only way you can kill a modern cpu is by overvolting it imo. and thats more degradation unless you actually fried it.

A long time ago tomshardware did a video on overheating on K7, PIII, and P4:

People can say what they want about pentium III and pentium 4 cpus. One thing they did right was thermal management. Only AMD has made cpus that in a realistic environment could get hot enough to overheat yet did not have any thermal management to deal with it. They finally addressed the issue in K8 (athlon 64).

From what I understand electromigration and dielectric breakdown (mainly due to heat induced deformations) are the main causes of long term cpu failure. Increased voltage and clock rate speed up electromigration (but extra voltage speeds it up a whole lot more). While heat is the main cause of dielectric breakdown. At a certain threshold voltage you can cause the junctions to fail completely even if you keep it cold and below the crossover threshold (I have no idea why, I would need to spend a lot more time on google or a physicist to tell me why). So you're mostly right.

Makes sense, luckily the newer Intel processors have very efficient thermal dissipation and rarely overheat unless you're doing something you shouldn't be (such as overclocking and increasing the voltage to unsafe levels and without proper cooling). For now, I will be more diligent in keeping my current desktop as free from dust as possible. Being able to run programs (including Dolphin) at full speed and at 1080p sure is enjoyable. I'll not be paranoid about usage, wear and tear or what have you. Thanks for all your advice and reassurance.
