CPU Thermal Throttling

The cluster focuses on discussions about thermal throttling in modern CPUs, including how processors reduce clock speeds to manage heat, questions about why it fails to prevent overheating or damage in some cases, and related hardware management techniques like undervolting.

Don’t they have thermal throttling issues?

Well, CPUs (at least Intel ones) underclock if the temperature is high.

How did the cpu throttling not kick-in and prevent this from happening? Mine gets hot and gets slow. It does not melt.

I thought CPUs and GPUs throttled themselves to keep the thermals safe?

Thermally it actually does and the CPU begins to throttle.

Presumably due to thermal throttling.

booi β€’ Oct 23, 2020 β€’ View on HN

hmm maybe less thermal throttling?

ComputerGuru β€’ Dec 21, 2021 β€’ View on HN

Modern CPUs will throttle or halt long before they fry themselves.

"could drive clock speeds down under heavy thermal loads"So now it just don't give a shit and fires away at the highest clock, without a care in the world about temperatures?The clock speed should go down under "heavy thermal load", that's not a bug...

It's quite possible that kind of thing has hard limits set by cooling.
