Is your PC in a refrigerator?

Of course not... just a quality cooling setup.

Sure, show me another one with a 6700K and lower temps, never seen one until now ;-)

The only ones I see with lower temps are delidded or had beter luck and can go lower with VCore.

Here's a guy who's running it on a normal air cooler, overclocked to 4.7, running 1.35v and he's at 80*C: http://www.tomshardware.co.uk/answers/id-2810472/cpu-temp-range-6700k.html

Here's a review where they overclocked it to 4.8GHz and the STRESS load is 76*C, 73*C in Prime: https://www.eteknix.com/intel-core-i7-6700k-i5-6600k-skylake-processors-review/8/

Here's a review where it with STOCK settings tops out at 65*C: http://www.legitreviews.com/intel-core-i7-6700k-skylake-processor-review_169935/16 "When we ran a run of Handbrake and found that the processor temperature topped out at 65C and the voltage jumped up to 1.2240V during this workload. The recovery time after the workload finished was the fastest we’ve ever seen as we literally went from running at 63-64C for a period of 10 minutes down to 30C in just a couple seconds." They had to run over 1.3v to get near 80*C as seen in the second picture.

Here's Tomshardware's torture test result; http://www.tomshardware.com/reviews/skylake-intel-core-i7-6700k-core-i5-6600k,4252-11.html - Doesn't get above 75*C at any time, and that's stock speeds and voltages, with a reference cooler. Their AIO result was "and the i7-6700K ends up at approximately 64 degrees Celsius. Even during peaks, it never surpasses the limit of 73 degrees Celsius."

And you can find plenty of that on Google. Your temperatures for an undervolted and stock speed CPU on an AIO are ... not good.

Oh sure, so why does everyone else on this planet see higher temps, even with a custom loop watercooling? And with OC...?

You're on LN2?

My 6700K @ stock speeds (and undervolted) with AiO watercooling reaches 80°C under load. 

My water-cooled 7700K at 5.0 GHz (1.35v) hovers around 45 deg C with P3D running.  High 60s with Prime95 running.  If I back it off a notch to 4.9 and 1.32v it's in the mid-high 30s running P3D.  Two GTX980Ti GPUs used to share the same loop, and they ran at 30-40 deg C.  This is on a water loop with dual 360mm triple-radiators, with 1/2" ID tubing mounted on a cooling stack external to the PC case.

Many consumer AIO water cooling kits are actually less capable than the better air coolers (e.g. Noctua NH-D14)

But if you're hitting 80 deg at stock speed and undervolted, I'd suspect that your 6700K has a defective TIM application under the lid.

BTW, Silicon Lottery will professionally delid your CPU and put in a proper application of high-quality liquid metal TIM for $25

Or if you are located in Europe you can buy the der8auer Deliding tool and do it yourself, this is what I did, it is not as hard as it looks when you have the right tools.

For the OP, I'd say your temps are perfectly normal for a stock (non delidded) CPU.

My overclocked 7700k was running in excess of 85c to 95c in P3D, and my case sounded more like a jet than the actual plane I was flying, this with an H100iv2 water cooler. Anything more than 85c is kind of scary in my opinion.

So delidding was the only option for me. After doing that, it will hardly break a maximum of 70c under max load.

There's other stuff to take into account like your room temperature, average weather where you live, etc. I live in a pretty hot place so that had to be taken into account; for instance I'll never see idle temps below 38c.

Cheers.

Wooo that's a lot mate, if im not mistaken 100c is the top threshold for that cpu, so you need to be careful, i have the same water cooler and i had problems with high temps until i replaced my thermal paste with this...

Yes indeed, my temps were extremely high and alarming. Not only does the 7700k run hot, but mine ran hotter than average probably due to the fact that I live in very hot weather, and have my PC set up in a tight corner.

I did not want to run P3D like that, which is why I ordered the Rock It Cool 88 delid tool. I considered the thermal paste you're linking to, and it's very good, but I went with the Thermal Grizzly Conductonaut (for the die) and Thermal Grizzly Kryonaut (for the heatsink).

My temps lowered considerably for every application, and I can now safely and confidently run any app without fear of those 95c spikes. I had some sleepless days I'll tell ya.

My liquid cooled CPU never leaves 38C... I've never checked my GPU temp.

Never leaves 38??  Even under full load?  What CPU have you got please and do you overclock it?

is it normal? Are they too high? Any solutions please?

No those temps are about correct for your setup, given that I don't know your ambient room temp.

Here is a video I made a few months ago that includes GPU/CPU temps running dual loop water cooled setup with CPU at 5Ghz and Titan X (pascal) OC'd  (in my video I'm actually doing a tip on how to improve shadow quality which as you can see from the video increase GPU load considerably):

Cheers, Rob.

After a short 1hr flight on my 6700k @4,5Ghz and Nvidia 1080ti.

CPU is air cooled by a Hyper 212 EVO, so a middle of the pack cooling solution.

Max Temps:

Core0 71c
Core1 71c
Core2 71c
Core3 73c

GPU: 80c

Unless you tell us your full spec, CPU model, delidded or not, type of water cooling, (AIO or full custom loop) the make and model, ambient temps, what you're loading the system with, whether you are referring to CPU temp or core temp... your 38C means nothing.

So, if are fine temps why I have lack of graphics(seconds of p3d4.1 freezes and the FPS drops) and back again to normal(in 1-2 seconds occur)

Geo

 

Run something else, a benchmark or stress test. Something like ROG Real Bench. If it happens with other demanding software too, as well as the sim, then yes, maybe hardware.

Find out if your system fails or passes the RealBench stress test? 

Freezing is often related to excessive temp but you need to test to determine, while monitoring core temp and GPU temp.

Are you overclocking? If so you could try with optimised defaults, no overclock. 

 

I've got one of the heat monster 7900X CPUs.  I've overclocked to 4.6 on all 10 cores at 1.18v and I'm running under load in P3D around mid 70s C.  I've never seen it get above 80C but I don't really want to push it any more than this.  I may bump up the voltage a bit because I'm seeing a few weird issues from time to time.

I idle around 30C.

I've got it in a room that stays about 68F.  I have the H115i AIO and two Noctua intake fans on it.  To maintain the mid 70Cs I need to put the AIO fans on full blast.  Opening the room windows when it's cold out really dropped my temps because the Noctuas can pull the cooler air in and not keep recycling the hot stuff that's being blown out by the case.

 

Under load (flight simming, video rendering), my CPU gets as hot as 77-82 degrees Celsius quite regularly. It’s an 3570k @ 4,3 GHz and it’s been running like that for the last 4 years without any problems. My GTX 1070 runs a bit cooler, normally in the low 70s.
