i7-7700K high stock temps, am I doing something wrong?

Hey,

First of all I apologize because I'm not a PC wizard and don't know much about the CPU temps. This is my first PC build, hence I'd need some advice.

I'm struggling because my i7-7700K temps seem a bit high even though I have a decent cooling (NZXT Kraken X62 AIO). I understood that the Kaby Lake flagship runs a bit hotter than previous Intel chips because of the higher clocks (4.2GHz w/ 4.5GHz boost). My 7700K is at stock clocks, no overclocking done. I'd be tempted to try it out but the seemingly high stock temps keep me from doing it.

I had to replace the NZXT Kraken X62 stock thermal paste because I had to take the cooler off at one point. I changed the paste to a Thermal Grizzly Hydronaut, which had pretty good reviews. I hope I did it right, I used something between a pea and a line method to apply the paste. So basically I should have a very good cooling and paste combo for my CPU now and expected to get good temps as well. However the idle temps sit around 30-35C now. I could have sworn my idle temps were around 25C for that short time I had the stock paste of NZXT kraken x62. It seems to me that many have idle temps around 25C as well. Am I doing something wrong or is this really normal? I also get spikes of over 70C while playing (Civilization VI), just spikes, not constant temps. I don't know if such spikes are normal. I haven't measured my average temps while gaming. On below you can find some stats. Please let me know if I'm missing something.

CPU Temps:

  • Idle: 30-35C
    Cinebench: ~ 64C
    Intel Extreme Tuning Utility CPU Test (100% Stress, 15min):
    Temp Range: ~50-70C, going up and down fast during the test
    Peaks: | #0 - 71C | #1 - 69C | #2 - 71C | #3 - 72C | package 72C
Things you should know:

Cooling:

  • CPU: NZXT Kraken X62 (100% Pump, 50% Fans), on top for exhaust
    Case: 3x 120mm intake in front (speed 40%), 1x 140mm exhaust (speed 40%) on the back
Other:

  • Case: NZXT H440 (2015 edition), not the most ideal for air flow but shouldn't matter that much
    Thermal Paste: Thermal Grizzly Hydronaut
    RAM: G.Skill Trident Z RGB (XMP enabled, 3200MHz, CL14, 1.2V)
    GPU: KFA2 GTX 1070 (HOF Edition)
    Room temperature: ~23C
Thank you so much in advance to anyone who bothers to help me. ❤

It seems to be within the limits but still quite high temps to my liking.. I wouldn't want to do something as extreme as to delid as I'm planning on selling the chip whenever I upgrade later.

I've had it for weeks already so I don't think the return is an option :( We don't have as generous return policies here either as in U.S. for example. The delid isn't really an option for me.. feeling really afraid and am hoping to sell the chip later when I upgrade after a few yers. I'm still pretty sure my temps were better with kraken x62 stock paste than with this highly rated Hydronaut.. what do you think about that? Could I have applied the paste wrong or something?

Yes, I used Akasa TIM clean and let it be a while before applying the new paste

I have a 1.5ml / 3.9g size of Hydronaut thermal paste. I kind of wasted it twice already when tried at first and I'm unsure how much I have left / how many applies a single paste tube of that size can do. Do you know if it last several tries?

Also I didn't use the spread method as suggested on the instructions but instead something between a pea and a line method. Should I try the spread method? Picture here: http://www.thermal-grizzly.com/images/anleitung_2.jpg
