Intel i5 4670K + Dual Fan Noctua NH-U14S CPU Cooler with 2nd NF-A15 in push-pull motion ...

... + Asus Z87 Sabertooth + Kingston HyperX Blu 16GB Kit (2x8GB Modules) 1600MHz 240-pin DDR3 Non-ECC CL10 Desktop Memory KHX1600C10D3B1K2/16G + nVidia GeForce GT 740 GPU + Corsair AX-750 PRO Gold.

What would be in terms of system stability and also in terms of not affecting the longevity of the processor, motherboard and rest of the hardware the safest and highest level of overclocking for:
A. with Video games and video editing and ...
B. If no video games would be played does the level of overclocking need to be more moderate while maintaining optimum results on all the other performances, like video streaming, recording uploads and downloads, web browsing opening dozens of web pages simultaneously and multitasking.
Other than overclocking the processor clock are there any other adjustments to do? Memory voltage?

Right now without the Overclocking and no Video games the CPU temperature has never exceeded 45C.

Could you also please point me to a tutorial that could explain how to proceed with overclocking step by step the safe and right way.
If even the minimal increase with overclocking would reduce the longevity of any piece of hardware I would have second thoughts about overclocking my system. I am almost 70 so I want this system to last my own lifespan.

I would appreciate your informed opinions and advice and to take into consideration the A and B ways above I would alternatively(one or the other) be using my PC.

Thank you kindly

    Intel sells the "K" versions with the intent that they have their multiplier increased.
    How high is variable so Intel can't guarantee any particular level.

    You are safe so long as you do not go wild on high voltages.

    I have become a bit jaded on the subject of haswell cooling for overclocking.
    How high you can OC is firstly determined by your luck in the bin lottery.
    I had high expectations from the Devil's canyon parts and their better thermals.
    I found out that the thermals really do not matter unless, perhaps, you are a competitive overclocker.
    Haswell runs quite cool, that is, until you raise the voltage past 1.25v or so.
    Once you go past 1.3v, then you really do need very good cooling to keep stress loads under say 85c.
    But, the consensus is that voltages higher than 1.30 are not a good thing for 24/7 usage.
    I have been unable to find any official Intel recommendation on what is a safe vcore limit.
    If you are an enthusiast, you can go higher.
    Even if you can handle the heat, how much do you really need that extra multiplier from say 4.4 to 4.6?
    My thought is that it is better to use the exotic cooling funds for a quieter and less expensive air cooler.
    I suggest a good tower air cooler like noctua or phanteks with 140mm fans.

    I stress test with OCCT.
    It will monitor temps and vcore. It will shut down at 85c.
    Just gradually raise the upper limit on multiplier and leave all else on auto.
