What's a stable overclock for a intel core i7 4770k that can be run 24/7, and will a h80i be able to habdle the heat that comes from this? At said overclock, wondering what you guys have your's set to before I do anything. I'm sorta new to this and want to know what other's have found to be stable, reliable, and not too hot for a h80i!
Thanks.

haswell oc capabilities are largely determined by your luck in getting a golden chip.
You can expect 4.0-4.5 on air.
Good liquid cooling might raise that by 0.1-0.2.

I do not much like all in one liquid coolers when a good air cooler can do the job.
A liquid cooler will be expensive, noisy, less reliable, and will not cool any better
in a well ventilated case.
Liquid cooling is really air cooling, it just puts the heat exchange in a different place.
The orientation of the radiator will cause a problem.
If you orient it to take in cool air from the outside, you will cool the cpu better, but the hot air then circulates inside the case heating up the graphics card and motherboard.
If you orient it to exhaust(which I think is better) ...

If you orient it to exhaust(which I think is better) , then your cpu cooling will be less effective because it uses pre heated case air.
And... I have read too many tales of woe when a liquid cooler leaks.
google "H100 leak"

I would simply use a noctua or Phanteks air cooler with a 140mm fan.
You will run cooler and quieter.

I test with OCCT. It gives you a nice set of graphs of voltage, temps, etc.

I might start at 4.0 and increase by .1 stopping when voltage gets to 1.2-1.25v.
Past that you get exponentially less returns.
For 24/7 use, I would back off another notch or two.

Also, over time, the thermal material will set, making cooling better.
Revisit your oc in a month or so, and you may do even better.
