I7 4770k High Temperature?

I want to build a PC with i7 4770k and I heard that haswell runs very hot (I'm new to PC building and overclocking).
I want to overclock it at least to 4.4 ghz but if it's too hot then reduce to 4.2ghz. Haswell has better iGpu that's why I want it instead of Ivy. I have a small budget so I won't buy Gpu for like 1 or 1,5 years (and I wouldn't really play games, I want to render).
So with the stock cooler and maybe a good Pc case with strong fans, can I overclock it? I'd set the cooler to max RPM along with the other fans. What else can I do without more money to keep the temp lower? At 4.4ghz the temperature is really high? Also I don't think that 75C is too hot because my laptops's i7 720QM idles at 65-70C (even with a big cooling pad) and renders or plays games at 100C and it has no problem with it since 4 years although it almost killed my HDD but... that's another story.

A decent air cooler (Hyper 212) is required for voltage levels above 1.15V..... (Generally up to 4.2 Ghz)
A top tier air cooler or AIO is required (Big 3 above or H110) for voltage levels between 1.20V-1.24V (Generally up to 4.4 Ghz)
At 1.25V-1.35V custom water loops w/ dual radiator water cooling solutions are advised. (Generally up to 4.6 Ghz)

Now again, "generally" above means the average...

NO WAY YOU CAN RUN OVERCLOCKED CPU WITH STOCK FAN AND IN HELP CASE FANS I RECOMMEND WATER COOLING WITH MAJOR BRANDS,GAMES AT 100 C ITS IMPOSSIBLE CAUSE U GET MAJOR LAG AND FINALLY CRASH,MONITORING WITH WITH SEVERAL SOFTWARE SHOWS INCORRECT RESULTS.

Try not to draw too many comparisons between your desktop and laptop. Those laptops processors are tough little bastards for lasting as long as they do running as hot as they do.

Do see: http://ark.intel.com/products/75123
Intel states that the hottest it should run with the stock fan is 72.3 Celsius

I think you can get away with 4.2 Ghz overclock, but there is always some wiggle room due to inconsistency in the manufacturing process (for better or for worse.)

You shouldn't ever try overclocking with a stock cooler. You'll maybe get a few MHz out of it, but if you want to overclock you really need to get an aftermarket cooler.

On the budget end, you're going to want a Cooler Master Hyper 212 EVO for around $30. If you have $70 or so, the NH-D14 or the Phantek ph-tc14pe. If you have a ton of cash, look into a custom water cooling loop.

You won't get satisfactory results with a stock cooler, and would be best suited to leave it at stock to prevent thermal throttling and a net loss in performance.

EDIT: As FloppyNacho said, do not expect to be able to run at similar temps as your laptop's CPU. Don't exceed 75C, as 72.72C is the rated max operational temperature (for Haswell). You would want something in the 60s for safe, constant use.

The i7-4770k is one of the hotter running CPUs and is generally not overclocked on a stock cooler simply for that reason alone. Since you are planning on rendering, you are making a good choice in the 4770k, but I would pair it with a decent cooler if you do OC it at all. For 4.2, I'd use a CM hyper212 EVO, if higher, start looking towards the larger towers like Noctua nf-d14.

CPUs are all different. Don't assume that just because a laptop was pushed to 100C, then a desktop will too. Generally speaking 100C is enough to start frying a desktops CPU.

At 100C your CPU is well past the throttling point.

CPU temps are a concern for 3 reasons:

1. Physical Damage in the short term
2. Throttling
3. Degradation of long term

Here's ya choices.....

1. Stock Cooler..... forget overclocking .... try running OCCT's CPU test at stock settings ..... it will shut down in seconds as temps pass the alarm level of 85C
2. Budget 3rd Party cooler ~ $30 i.e. Hyper 212
3. Hi End 3rd Party Cooler ~ $75 i.e. Big 3 = Phanteks PH-TC14-PE, Noctua DH-14, Thermalright Silver Arrow

Heat is dependent on voltage.

A decent air cooler (Hyper 212) is required for voltage levels above 1.15V..... (Generally up to 4.2 Ghz)
A top tier air cooler or AIO is required (Big 3 above or H110) for voltage levels between 1.20V-1.24V (Generally up to 4.4 Ghz)
At 1.25V-1.35V custom water loops w/ dual radiator water cooling solutions are advised. (Generally up to 4.6 Ghz)

Now again, "generally" above means the average chip.... if you do well in the silicon lottery you can do better.

Also keep in mind that if you use anything that uses AVX instructions, you can expect voltages at 0.10 above what you set in BIOS. A BIOS upgrade took my 4.6 OC from requiring 1.325 volts to 1.375 volts (280 + 420 radiators)..... which under AVX took me way up to 1.48 voltage peaks which, while temps were fine at 74C, I was unhappy with those voltages. If ya sure you never gonna use anything with AVX.... then you can set voltages higher.

Okay. I checked out that Cooler Master hyper 212 Evo... and it's HUGE! Will it fit in the case? o_O Also installing it to the motherboard seems a little bit complicated to me. But I like the price. How cool it will keep my CPU? Is it good for 4.3 or 4.4ghz or that's too much? Actually I'd like 4.3ghz or 4.5ghz but not if it's too hot.

A Corsair 500R ($89) will fit any of the above coolers:
