Hi - I have a noctua dh-15 that I know is seated right with arctic silver. At quiet CPU cooling and 4.5ghz I hit 72 c. At turbo CPU cooling and 4.5 ghz I hit 67-68c max. If I oc to 4.8 ghz I get 80-82 c. I don't want liquid cooling because I find the radiator too loud
I called intel to see if that is too hot given I used to have chips like i7 4930k or 6600k and I never saw temps on air cooling above 60c.
The intel rep said because they are new people don't understand that Kaby lake runs much hotter and tha anything under one hundred centigrade for the package is ok
My system recovers very fast as within ten seconds of ending a game it comes down to the fifties centigrade
Is it true that eighty centigrade is ok for kaby lake and perfectly fine? Please let me know only if you specifically have experience and knowledge of kaby lake given the intel tech guy saying it is just different than last gen and runs hot
Thanks in advance

Q: What is your Core voltage?
Q: What is your ambient temperature?
Here's the recommended operating range for Core temperature:
80C
Hot (100% Load)
75C
Warm
70C
Warm (Heavy Load)
60C
Norm
50C
Norm (Medium Load)
40C
Norm
30C
Cool (Idle)
25C
Cool
Core temperatures up to 80C are safe.
The following is from SiliconLottery.com, where they bin CPU's and offer de-lidding service:

"Temperature improvements vary depending on processor sample and architecture. Temperatures under an overclocked load (1.3V-1.4V) will decrease anywhere from 5° to 25°C. Typical temperature improvements are listed below:
Ivy Bridge: 10°C to 25°C
Haswell: 10°C to 25°C
Devil's Canyon: 7°C to 15°C
Broadwell: 8°C to 18°C
Skylake: 8°C to 18°C
Kaby Lake: 12° to 25°C"
I purchased a 5.0 GHz i7 7700K from Silicon Lottery. At 1.368 Vcore and 22C ambient temperature, my hottest Core running Prime95 V26.6 Small FFT's is 73C using a Cooler Master TPC 812, which is a high-end single tower air cooler that is slightly less capable than your Noctua NH-D15 at a much lighter weight. I also owned a 4.8 GHz i7 6700K, again purchased from Silicon Lottery. The hottest Core was 67C under the same conditions with 1.400 Vcore.
Previously I owned an i7 4770K at 4.7 GHz, which I delidded myself. The hottest Core was 69C at 1.300 Vcore. I also owned an i7 3770K at 4.6 and 1.300 Vcore I delidded with similar results. Prior to delidding, Core temperatures were ridiculously high, well into the 90's.
All the processors listed above by Silicon Lottery are TIM'd, whereas the 2nd Gen Sandy Bridge and previous processors are soldered. In my opinion, Sandy Bridge processors were the last mainstream desktop processors released by Intel that were thermally consistent, predictable and well behaved.
Intel moved away from soldering, because they used "Indium" in their solder, which has a relatively low melting point and high thermal conductivity, but is an exotic and expensive element. Thermal Interface Material, or "TIM" is inexpensive, but has a relatively low thermal conductivity (1/8th to 1/10th) compared to Indium. A Dow-Corning compound was used on many processor variants.
You might want to consider sending your CPU to Silicon Lottery, where they will delid it for you.
