Deschutes or newer = integrated thermal sensor.

I don't think a pentium 3 really needs a temperature sensor

Famous last words.

But the only way to read it is via the motherboard SIO chip 🙁

Does it? To my knowledge they don't really get that hot while using even pretty basic heat sinks.

Maybe the 1ghz+ ones do. But I think sub 1ghz models are fine so long as the heat sink is installed correctly.

Stock cooling on slot 1 CPUs could go very hot after 20+ years with original thermal paste. Some OEMs were using "yellow gum" or other horrible solutions. External sensors won't tell s**t in such situations.

It depends on the heatsink type, if it uses fans and they fail then it's going to warm up quite quickly. I feel monitoring both the temperature and fan speeds is sensible, further if the temperature increases after a few years it's time to renew the thermal paste.

I guess not monitoring it would add to the excitement of some games !

Not with general recommendations to build P3 retrorig.

Guess it comes back to the old "at what point do you need a heaksink / thermal paste" debate.

I guess my confusion stems from.... if there's no temperature sensor , then overheating probably wasn't much of a concern.

Overheating was a major concern since Pentium 66. In fact, some S7 era mobos were using external sensor.

Yeah but a lot of s7 machines and even slot 1 didn't even use/need thermal paste. Some just ran big passive heat sinks too.

Anyway , I assume the p3 667mhz model doesn't mind the lack of thermal paste as it made it through the whole windows install without much trouble. Now that it's done it's getting repasted anyway.
