I am considering buying a cpu cooler and am wondering how high I can get whith the h110 extreme and the kraken x60 while still getting safe temperatures atleast under 80 at full load. ALso is there any better watercooling thing for the cpu. Thanks in advance

You should be able to reach the upper end of 4 GHz without too much heat build up, it partially depends on the cpu too, some are better than others.

It said the 4770k in the title

I mean the specific CPU you get, my 4770k may perform much better or worse than yours based on manufacturing quality. I had an i7-920 that couldn't overclock at all, it had to run at stock settings or it would crash.

Overclocking results vary vastly from chip to chip, this isn't something that we can tell you with any confidence. As far as the Water Cooling things go, the h110 and the kraken x60 are very good things, and would cool your CPU nicely...

Not all 4770Ks are the same, some will do 4.9Ghz and some won't get above 4.0Ghz. Whilst temperatures are often the limiting factor, make sure you have a good motherboard so that you don't need huge amount of voltage to get higher clocks.

Wait so the chips are all the same, correct? But the motherboard and psu is what decides how much you csn overclock

If thats the case then I have a 750watt evga gold certified psu and an msi z87 g-45 gaming motherbaord about what overclock could I get with that is the information that varies

The chips are not all the same - thus the term "silicon lottery" regarding luck in getting a good overclocker.

With overclocking there is no GUARANTEE.The chips are not all the same. Asus has tested hundreds of Haswell CPUs as part of its effort to profile the chip for auto-tuning algorithms. According to the motherboard maker, Intel's new hotness has a little less overclocking headroom than Ivy Bridge does. Perhaps more importantly, Haswell apparently has more variance from chip to chip, especially in the voltages necessary to hit specific speeds.

Of the processors Asus has tested, 70% hit 4.5GHz, 30% reached 4.6GHz, and 20% made 4.7GHz. Only 10% were stable at 4.8GHz. Heat is reportedly the limiting factor, and Asus recommends using a dual-fan water cooler to prevent thermal throttling past about 4.5GHz or 1.25V. Going beyond 1.35V is apparently problematic even for high-end water coolers.

Can you somehow find out which ones can and which cant

Yeah, as has been said - You will have to test to find out. I would recommend doing so in small increments. I have a haswell that I keep at 5Ghz all the time with a VCore of 1.28 and its fine. I've read some people can't even break 4Ghz with 1.35 (which is getting too high for Haswell).

You should also consider non-closed loop set-ups, it will cost you a bit more but I think it is worth it. I have an XSPC kit (see sig) and I've decided I want to see how much I can get out of my chip now, and I can quite easily by customising my loop.
