Depending on this, your CPU was labeled and packaged.Īll in all we are maybe talking about a few weeks to months difference in an estimated minimum life of a decade or more. Even the best cooling devices can not prevent the inner core from a rising temperature.īut since the manufacturers measured several parameters from your individual CPU, they were able to estimate, what temperature your individual CPU can withstand. So running your CPU on a 100% level will lead to a higher temperature in the CPU. Other than that - the higher the temperature the shorter the life span of the product.

But these days are gone, your Core 2 will shut down, if the temperature reaches a certain level. Before there were overheat preventions built into the CPU, there were several videos on the net, that showed CPU buring a few seconds after booting the machine. If you do overload your PSU, it should also automatically shutdown, but on cheaper units restarts and Bluse Screens of Death are possible too.Ī short answer will be: Yes, running at 100% will definitely damage your machine, but you will not live to see it - because it can take several years.Ī CPU usage of 100% will not kill your processor instantly - if it has proper cooling. They should be within ±5% of stated voltage for positive voltages and within ☑0% for negative voltages. If the temperatures rise to dangerous levels (I can't tell you what is dangerous for you, since you provided almost no information), you'll be able to see and stop the demanding program.Īlso the temperatures will rise quickly, so if they aren't dangerous after 20 or so minutes, then they probably won't reach dangerous levels.Īnother thing to watch out for are low voltages. My recommendation is to get some sort of hardware monitoring program like HWMonitor for example and run it while running your task.

(I've run my laptop for days under 100% load for CPUs and GPU and didn't have any problems).Īlso, if your computer is relatively new (say less than 5 years old) it will shut down automatically in case it overheats. In general, your computer should be able to sustain 100% load for long time.
