Stock i7 4770k & GTX 780 DirectCU II running hot?

cpu under 80/gpu under 95 is fine. but you prob dont want the hair dryer effect.
I suggests getting a new cooling. a corsair hydro series or a hyper 212 Evo or any Noctua cooler
Atleash change the thermal paste as that often solves the prob

yeah
But u should get a liquid one or a 212 evo if u plan to do some serious OC

Little bit of a side track here, I happen to notice you have the same motherboard as me. With that ASUS motherboard, ASUS ships a CD with all its drivers and tools that you can use. Have you tried using AISuiteIII? I find it is a really useful tool for monitoring temperatures on your board and any clock settings being used. Now i'm not totally side tracking when I mention this because it is not recommended to run more than one tool at a time to monitor temperatures. So if you are running the AISuite and Core Temp at the same time it cold potentially give you inaccurate readings. (Example: http://rog.asus.com/forum/showthread.php?34206-AI-Suite-III-Incorrect-Temperatures)

I am running a similar rig and I don't normally see my CPU temps going quite as high (and I am using the Intel STOCK COOLER), even under 25-50% load at the base clock (3.8 with Turbo). My Rig:
ASUS GTX 770
Maximus VI formula,
Core i5 4670k (4xxx implies 4th gen I.E. Haswell)

How much CPU usage are you seeing when running the game?

I do agree with Yingda Wang, as long as you are maintaining under those temperatures then you shouldn't have any problems. To increase the lifespan of your components its always good to keep them as cool as possible. That said, IMO, the cooler you are currently using should be doing a better job than it is right now. Benchmark tests: (http://www.hardwaresecrets.com/printpage/Cooler-Master-V8-GTS-CPU-Cooler-Review/1796) Now the temps you are reaching are not a cause for an alarm, but if you want put in the time I would consider re-seating the CPU cooler. You already purchased an aftermarket CPU cooler (a decent one at that) there is no need to go out and buy a new one unless its performance is slipping because of age. I really do think you should be getting better performance out of that cooler.

Totally neglected the GPU, I think those are pretty stable temps when running BF4 on ultra.

EDIT: When I say "re-seating the CPU cooler" I am also implying that the person would clean and reapply the thermal grease as well.

I guess we should get a consensus on which temperature is more accurate. I had been using AISuiteIII and Corsair Link and despite a few degrees offset, they both seemed to be pretty consistent with my CPU temps. So I had believed AISuiteIII was reading the temps correctly. Also what version of Core Temp are you running? I'm pretty sure there were issues with earlier versions which caused incorrect temp readings.

From what I hear speedfan and HWMonitor (http://www.cpuid.com/softwares/hwmonitor.html) are supposed to be accurate, you can give that a try to see which of the two readings (CT or AISuite) is closer.

If its not a matter of reliability then it could also be the fact that both these applications are reading from different sensors. There are multiple sensors that measure temperature in the latest chips so its plausible they are both correct but reading different sensors. The hottest temps in a CPU should be in the cores themselves, so if you find an application or two that reads the actual core temps (4 cores in your case) and you get a consensus, those should be the only temps you should be concerned with.

Interested in your results! Thanks for making me doubt my own solution :-D

Well like I said the cores are your concern. The CPU temp is basically the temperature of the processor as a whole (calculated by thermal sensors on the die but not located on the actual cores). The core temps are always going to be the hottest and can be used as the "official" max temp of the CPU. The thermal diodes (known as Digital Thermal Sensors) on the cores is what Intel uses for their built-in thermal throttling and thermal shutdown fail-safe features.

There is a lot of discussion on this particular topic, IMO, core temps would be the temperature you would be most concerned because it would be the first thing to hit any threshold however don't discount the cpu temp. The heat from the cores obviously dissipates to the rest of the die which would raise the CPU temp. If you are not managing the temperature of the die then the cores will not be able to dissipate heat and cause overheating issues (triggering thermal throttling).

All that said, there is one very important item to consider, which I just found out myself. All these third party tools that monitor core temp are doing the calculations themselves. The chip itself actually monitors core tempuratures based on how far the core is from its max temps. So lets say Intel says your cores max temps are 100C. At max usage lets say your core is reading 20C. This means the cores temp is 100C-20C=80C, your core is running at 80 degrees. When using core temps its important that the application you are using is able to determine the CPU's max core temp. If the actual max is 100C but the app thinks its 80C, then when the core reads 10C, the app would report 70C instead of the actual temp of 90C. Source (http://forums.evga.com/tm.aspx?m=1980567)

IMO, if your are keeping your CPU temp under 60-65C then I wouldn't worry about the cores hitting 70-75C. The core temps should proportionally rise and fall with the CPU temp when maintaining a certain amount of CPU activity. If you are keeping the CPU temp at a good temp (not just under the maximum) then the cores will spike to higher temps but will always level out before any harm becomes of the CPU.

FYI, did a little of my own testing yesterday. While gaming, my CPU(clocked at the stock 3.4,3.8 with turbo) was running at about 35-40% usage consistently while the application was open. I left my monitors up on my second screen and monitored the temps while playing. My results were pretty consistent, hovering around 55-60C for all my cores as well as my CPU temp. I used several applications throughout this testing including (AisuiteIII, Corsair link, HWMonitor, RealTemps). AISuiteIII did read, on average, 5 degrees less than any of the other applications. The rest were pretty consistent with one another.

Given everything discussed in this thread, I stick to my original assessment, your CPU temps are not a big concern. In your case, I do not know what temps to trust, the variance between the cores and CPU seem to be too much for both temps to be reading correctly. If you are actually hitting low to mid 70s consistently then try re-seating the cooler. It should be cooler than that especially if you are not using more that 50% CPU usage consistantly which games should do very often.
