No desktop CPU I’ve ever used has remained stable at 100 degrees.
My 14900k crashes almost immediately at that temp.
3 hours at 100 degrees is obscene.
Besides AMD CPUs of the early 2000s going up in smokes without working cooling, they all throttle before they become temporarily or permanently unstable. Otherwise they are bad.
I've never had a desktop part fail due to max temperatures, but I don't think I've owned one that advertises nor allows itself to reach or remain at 100c or higher.
If someone sells a CPU that's specified to work at 100 or 110 degrees and it doesn't then it's either defective or fraudulent, no excuses.
And any CPU from the last decade will just throttle down if it gets too hot. That's how the entire "Turbo" thing works: go as fast as we can until it gets too hot, after which it throttles down.
A great and terrible book, Gibson repeatedly throwing you in to mountains of not yet explained language and concepts before dragging you out of confusion a chapter later is frustrating and tiresome, however I could not help coming back for more. I regret nothing.
I have to read his books twice. The first time I just plow through, confused the entire time. The second pass is where I can enjoy it, but there are still a lot of times where I read a sentence and struggle with parsing it.
Gibson's works definitely demand multiple reads, IMO. I have read Neuromancer around 5 times now, and I'd say I "get it" a little bit more each time I read it. Even now, 30+ years after I read it the first time, it still fascinates on a re-read.
A 700W 80+ power supply will generally be more efficient pushing 450W than a 500W PSU because the wattage output is in the mid-range where peak efficiency generally occurs.
