We all talk about CPU's getting overheated and how to fix it.

And now I am curious about what temprature is too cold for the processor to operate properly?

We seen in the THG 5ghz video that the CPU worked with -190c tempratures.


After all CPU has electrons that are moving very fast so how cold a CPU needs to be in order to prevent it from working?

I wonder if anyone here knows.

I don't think a CPU can be too cold. If the rest of a structure is immobile, it does not prevent electrons from moving when you apply a potential. The moving electrons would then heat up the CPU, and you'd have to cool it down again.

In fact, and I'm not at all sure, I read somewhere a while ago that semiconducting materials 'heal' themselves at extremely cold temps.

When i was looking up a A64 2800+ to buy for my new computer it had a temp ranfe listing...keep it below 100C and it had a bottom number too....i can't remember but its rediculously low...i think like 150below or something.

You can take your PCU above 100 but it may not work and also its not reccomended. Also i doubt it would like to be super cold...ie, just above 0K.
the heat from the electrons moving to heat it and then a rapid cool would stress the system. It would be a rapid heating and cooling and that would stress the metal.

Pyrex can handle extreme highs and extreme lows....but if you have dry ice in water in a pyrex container.....dont try to boil the water, it will make the pyrex explode. and i dont mean crack. I saw it do that...i was picking up glass across the room and all over the kitchen.

This all assumes that the transistors firing would make a large heat up....but if the heat up is more gradual then very low temps should be easily done...it would still lower the life of the PCU, but thats not the question.

Maximum PC actually did an article about this. They asked both amd and intel how low the procs could go. Intel doesn't guarantee theirs below 5 degrees celcius. They make special procs that can go lower for things like ice station research labs. AMD I believe said about the same thing. But of course, there's always a difference between what the companies say the chips can do and what the chips themselves can actually do.
