Lets say I have a CPU with a recommended max voltage of 1.4V and I put the volts at like 1.6V or 1.8V or even 2.0V but I somehow kept the temperature at the same temp as if I had kept it at stock volts. Would my CPU get damaged at all? How much would the lifespan decrease by? 50% 25%? Would it still last me a few years or die after a few months?

With Intel, the recommended voltage is 1.5v for the CPU, overclocking this voltage will decrease the life time of the CPU. What percentage: It is all random. Normally it is stated in years like, continuous overclocking may give CPU the 3 years life or so.

Yes, it can damage the CPU. Don't cross the threshold of voltage. Overclock till your system is stable. Beyond that don't do it.

In all likelihood, you'll have upgraded the processor by the time overclocking has taken its toll, providing you don't go nuts on the clock speed.

You should not, under any circumstances increase the voltage beyond 1.5V. It's dangerous and simply not necessary. The extra heat at 1.6V, 1.8V and 2.0V will be immense and you'll seriously damage the components. Most motherboards that support overclocking let you change the voltage in 0.005 increments, so the gap between 1.5V and 2.0V is huge.


The lifespan of your CPU is determined by heat, and realistically, the only way to keep the heat down at 2.0V is to use LN2.

LN2! Seriously! Well, OP Liquid Nitrogen is used in extreme overclocking.

General Note: Overclock as long as system is stabilize and ensure the proper cooling system for the CPU and case. Produced heat from overclock components needs to be dissipated and exhausted continuously otherwise the heat will damage the mobo and other components as well.

Good Luck

So if I put an Intel CPU at 2.0V and put the clock up to something crazy but kept the temp at like 50°C under full load, would the CPU be damaged at all?

EDIT: This is all theoretical by the way. I don't plan on actually doing this, just interested.

As long as the heat is down it should be fine. At least in theory.

As long as the temps are down or maintained at low values, there will hardly be any effect on the components. But, remember, this can be ideal situation on sandy bridge/ivy bridge architecture because their VRM are not built on the chip itself, therefore they've less heating problem as compared to Haswell series CPUs because their VRM is built right onto the chip so they are much hoter than previous generation CPUs but still are more powerful and efficient.

Voltage at 2.0v! Wowwwwwww. Theoretically.
