I don't have any metrics, but can offer an anecdote: I had a laptop in a
sealed backpack die on me a couple of years back, presumably because it cooked

IIRC, it was a Dell Precision M4800 -- optimized more for processing power,
high screen resolution, and the biggest nipple-sporting keyboard I could find
rather than for portability[0]. It ran warm most of the time, and sometimes
downright hot -- but usually out in the open sitting on my desk or kitchen
counter. The fans (one for the CPU, one for the graphics processor) ran
often[1] and I had to replace the one for the graphics processor when the
first one wore out.

My typical work flow was to suspend it at the office, throw it in my backpack,
and open it back up within an hour or so of being home. The day I found it
dead, though, I had not re-opened it the prior night, and that morning there
was no sign of life. I suspect that it didn't properly suspend for some
reason, so it was probably going nuts inside the bag. And the timing for that
was bad because I happened to not open it overnight.

So how hot before it's permanently damaged? I've got one data point that says
less than ten hours running hot in a contained space. However hot that is...

Take care,

[0] That's how I roll.

[1] These days I would describe it as "loud", too.
