Does voltage matter?

Does voltage matter if you can keep the processor cool enough?

I personally have a 3570k and have gone quite a bit above the recommended max voltage but I am using a All in one 240mm cooling unit and in my Aida 64 stress test my max temperature is 78 degrees.

it is at 4.5GHZ and the voltage is 1.425. JJ from asus said the max he recommended for ivy bridge is 1.325 but his particular chip and cooler was at a much higher temperature than mine even though my voltage is higher

If you can control the temps well, it wont matter as much.

Just keep in mind increasing the voltage on your CPU too far will significantly decrease its life span.

That is kind of high and will degrade the processor quicker.

 

One thing that will help is to make sure you are overclocking with an offset not static voltage that way your processor won't be on that really high voltage as often.

Not only will this make it last longer, but it will produce less heat at idle and reduce power consumption.

There are different batches of chips. 

 

Some overclock at lower volts and get higher temps and others get higher volts but lower temps. 

 

The balance between the two are more rare.

Keeping a processor cooler can lead to it requiring less voltage to run faster (principles behind LN2 runs, science etc). Sometimes throwing more voltage isn't the right solution. For example Phenom II's react better from being colder than adding more voltage even when on air/water. You're running way too much voltage in that i5 imo.

This is the simplest answer.  Heat kills processors.  Boost up the voltage keeping the heat under 90deg, during a 10hour intel burn test burn.  Let it run and build up heat.  More voltage will increase heat, even without the increase of the cpu increases.  You also will find out during this point that your current setup isn't stable and needs more voltage to even run your current setup during long cycles.  I used to use prime95 but intel burn test really works the system.  I was finding instability a lot sooner, compared to prime95 (yes even while using the multi core/thread version).

 

With the newer chips, since they run cooler, I would keep the below 80deg because that means you are pushing a lot more power into the chip.  No matter what, if you pump too much voltage into a chip, for a long time, it will take a few years off the chip.  If you will only be running that setup for a few years and you don't mind, push it and see.  Honestly, I am running a i7 930 at 4.1ghz and the cpu is only holding back my gaming performance 10% or so.  My video cards are my next weak link.  All newest gen or last gen i5's or i7s overclocked, is plenty powerful enough for anything out now.  If if you are playing a game, then your video cards would be the next slow point.  If you don't have an SSD, then that would be a huge bottleneck.  Etc Etc

If you only have the fpu test checked your temps will be much higher. You prolly had four tests checked which is why the temps were kind of nice for the voltage.

 

Oh and ouch 1.4v for 45...
