Windows 7 - overclocking and processor?

does overclocking shorten the life of processor or anythings?

Yes, since you're running the CPU/memory/videocard/etc hotter and stressing them more.

In practice it doesn't really matter however, since electronics tend to live very long and rarely fail (unlike harddisks for example). Reckless overclocking and/or insufficient cooling can put a very sudden end to things on the other hand.

In relation to OP's Question Yes. It generates more temperature, and stresses the system to a level unattainable by normal clock speeds. If you're looking/are overclocking, you have to be careful on what settings you use.

however poor airflow and case cooling can also shorten components life as they will get hotter

I upgrade my rig every 1-2 years, so nothing to worry about, but a good cooler and airflow is advised for overclocking.

Yes, it certainly can. If you take care when overclocking though, the risk fairly minimal. Overclocking creates more heat, and too much heat will absolutely hurt the processor over time. If you plan to overclock, it is worth considering buying a better CPU cooler, although certainly not necessary if you are only clocking a little bit. Watching the CPU core temperatures is a must. Most overclockers like to keep them cool (it improves the lifespan). For most CPUs, damage will occur around 95+ deg C, although you certainly want to keep it cooler than that. Programs like CoreTemp are good for keeping track of temperatures.

As another note, in your system spec, you said you have a netbook - not only is it dangerous to overclock laptops because of cooling problems, it also usually can't be done in the first place :P

Anyway, hope that is helpful.

Raising the temperature and voltage of the processor as you do in overclocking increases electromagnetic effects which can erode the connections between the components in the CPU and associated chipset. Electromigration effects increase exponentially with temperature and quadratically with voltage. If you keep within the specifications of temperature and voltage set by the manufacturer, then the chips will last as long as the manufacturer has specified. If you go out of that range, which you will with overclocking, then the lifetime will probably be less than the spec.

AS already mentioned, heat is the primary contributor followed by voltage.

I agree, on principle, yes. Some CPU's are designed to be overclockable. They actually have built in headroom if you will. With correct cooling and voltages, they will last just as long as with the designed speed. But on the face of the question, the ultimate life of the CPU would likely be shortened. A Guy
