AMD vs Intel: Which gets hotter?

Intel cpu's can generally handle higher temperatures compared to those vishera amd cpu's such as the fx 8350.
However Intel cpu's can reach higher temperatures which could lead to your room getting hotter overtime if you plan to put load on it by gaming. However I'm not 100% sure on this.

But i do know that my fx 8350 hit around 55-60c when playing games.

AMD chips have lower safe temperatures than Intel. 70C+ (not sure, it might shut down by itself even) for an AMD FX is like slowly grilling it to death. Haswell can handle 85C without any damage (although might shave a bit of the chips life - like lasting 1 year less out of 5-6-7 years). Due to the lower temperature that AMD requires - all that heat has to be taken out. AMD chips create larger amounts of heat, since they use more power, even if they stay at lower temps. The degrees of the heat and the amount of the heat are 2 different physical properties.

In terms of stock cooling, intel and amd are about equal. Haswell cpus usually run hotter with their stock cooler. In other words, they all work fine if no over clocking is involved.
Intel CPUs has a higher temperature threshold

really depends on how hard you want to push them but intel can usually take higher temps

That is only true in open bench/open case. Haswell runs hotter compared in C to AMD and cooler compared to its maximum operating temperature compared to AMDs to its own maximum operating temperature. Intel also quieter, with it's stock cooling, because of the higher thermal ceiling. As I said, AMD produces larger amounts of heat, which makes a case with good airflow more important.

intel is hotter then amd, just look at max safe temps and average temps under load.

Ok, so for a 3rd time. Amount of heat and the Degrees are two entirely different properties. For processors - the most important factors for being "hotter" is the Amount of heat produced which depends on power consumed and the thermal density.

Just that you see more degrees on a CPU does not mean that the CPU is hotter than another. Heat is not just a number in degrees. A frying pan reaches 200 C on its surface. A radiator goes to 60. Are you telling me that the frying pan is going to heat your house better. Learn some basics physics.

Intel sucks half the power FX does. Intel has higher thermal density. But Intel produces less heat as in "volume". And that is the answer to the question.

no, the real answer to the OP's question was : it does not make any difference a 29$ cooler master hyper 212 cpu cooler will cool both cpu's down to a very satisfying degree...

And about power consumption the difference between both CPU (i7-4770 and FX-8350) in energy is about 68 cents a month for a 3 hours a day use in the US wich is about 8.16$ a year , i made this calculation before getting my FX-8320, wich i'm very happy with and outperforms pretty much any reviews i find on the internet, wich is quite strange BTW...

From the OP:

"I would prefer to avoid needing an aftermarket cooling system"

Makes your " a 29$ cooler master hyper 212 cpu cooler will cool both cpu's down to a very satisfying degree..." completely irrelevant and in the opposite direction.

2.
Power consumption is directly connected to heat. A CPU that consumes 65W will produce less amount of heat than a CPU that consumes 95 or 125. The degrees of the chip depends on the amount of heat produced taken with the thermal density. Just look at the TDP (Thermal Design Power) on both the FX and their I counterparts. This is the relevant information you have to be looking at. Not the Max operating temps.

3.
Why did you even bring up the price of electricity. Completely irrelevant.

I'll take my time to answer this.

I bought an AMD FX-8350 a year ago, even knowing Intel i7s are faster, but my budget wouldn't allow me to go for one of those. i5 seems like good options, but I'm devoted to AMD, only Intel processor I had was the pentium 1. FX-8350 cooler looked like a problem before I even bought all the parts of the system, but then I was surprissed to see how well it worked. It's a very nice looking hear spreader and an awful and noisy cooler. The CPU wouldn't rise high temps, even in summer with 40ºC ambient the CPU was working really well, but I admit that it was noisy. I had 4 extra coolers then (1 front intake, 1 rear exhaust, 2 top exhaust, all of them 120mm coolermaster, really good coolers and run smooth, recommended). My case is an Aerocool templarius telum black, not a great case but it has room for every single thing I want. On League of Legends, the CPU would rise to 40º, on summer it didn't pass the 50º, I also open different programs and my beloved Firefox. On Metro 2033 with the top settings on full hd my CPU didn't go past the 55º, and on summer it didn't reach 60ºC. The only time I reached more than 65ºC (always talking about cpu, not socket) was when I tried Prime95, it didn't take more than 1 minute to achieve that number :S. I changed my stock cooler, knowing I really didn't need to, but i like to watch movies and I wanted my system to run smoother, so I installed the famous CM Hyper 212 EVO (recommended).
On the other hand, a friend of mine recently bought a new PC with an Intel Core i5 4670k. I gotta say, it's fast, pretty much like my system, but some programs add a little more efficiency (intel and gigabyte softwares). Thing is, that stock cooler is awful, and also the heat spreader. Really people, what is wrong with you all? In a lot of forums I read that Intel CPUs run cooler than AMDs. That's BULLSHIT, they do run hotter, and their stock cooler is a real problem. Even when we finished assembling the system, the cooler didn't spin at all, it started when the CPU reached 90º. When we called to RMA the product they told us to strech the cable, and then the problem was gone, but that means built in quality is horrible, I've never had that problem with all the AMDs I've worked with, and this Intel CPU was brand new. The temps are still a problem, so my friend is saving some money to go for the same cooler I got.
Intel dissapointed me. It's CPUs might be fast, and they are a few generations ahead of AMD, but the quality was just not acceptable. Imagine if we didn't install a VGA and that stock cooler had to deal with the heat of both the CPU and the IGP.
I'll also add that, even if Intel parts have higher temps limits, I don't like my CPU running constantly at 70ºC, it might rise the heat inside the case.
