Sub-zero Temps

[compnoob]

ok so i know its the sensors failing but my moms computer says the cpu is running at -55c.

so just wondering theoretically what would happen if a computer did try and run at remotely those temps, or what is the fail temp of most computer parts

It's probably not even a failing sensor, but rather one that's mis-reporting. It won't affect anything.

Maybe not even run? Too cold for the circuit to move?

The PC should run fine, pro overclockers that use liquid helium and liquid nitrogen can get their CPU below -100°C as shown here:

The CPU got to reach below -140°C before it shut down. You should be worried only if the CPU sensor mis-reports in higher temperatures causing it to falsely thermally shut down. I'm experiencing this right now with my RIVE, it is reporting 89°C at POST with a correctly mounted liquid cooler.

It would still work, most components can run at super cool temps, like when being cooled by LN2

Yes they would indeed run just fine. Personally I have only experienced a sensor reporting back sub zero temperatures once, and that was after the temps had hit 102C and kept rising. Goodbye laptop is all I'm saying. :D If your mothers computer is still running that is not the case in any shape or form though. :)

Although your correct they do drop they temps really low they also only do it for seconds minutes at max before they boot the pc and which point the overclock raises that temp very high very fast and then crashes thus giving only a split second for the screenshot of course that's only suicide clocking but suicide is the only ones that drop it that low of course you are correct and extreme ocs that are benchable are still droped to -50 -80c and closely kept at that level using a blowtorch

I think you need to read up on overclocking mate.
