specs

i-7 7700k

as rock z-270

asus EX-1050ti oc

16gb ripjaws 3200

theramaltake riing silent 12 pro

3 case fans

all system on stock ,and ram too, only cooler put on 100% when temp. is 70

idile temp, 35-40 -spike when i open browser or (apps,new tab) for 10-15 on 3-4sec
playing BF1 70-75 spike till 81, after 2h play around 80 spike 85 on 2-3 sec
then i open case and touch cooler which is only light warm far away from hot
then i try open my BF1 and when is load put in background and try open browser and new tabs and no spike just for 1-2 degrease

is that normal temp. by 7700k

Yes, that is normal. KabyLake CPU's run warmer than earlier CPU's due to Intel using crap thermal paste.

Btw you can probably oc a bit without increasing voltage so you can have 200mhz or more for about the same temps, or under volt it at stock speeds for lower temps.

hrvojevlahovic,

On behalf of Tom's Hardware Moderator Team, welcome aboard!

Core temperatures respond instantly to changes in load.

Intel’s specification for Digital Thermal Sensor (DTS) response time is 256 milliseconds, or about 1/4th of a second. Since Windows has dozens of Processes and Services running in the background, it’s normal to see rapid and random Core temperature “spikes” or fluctuations, especially during the first few minutes after startup, which should eventually settle. Any software activity will show some percentage of CPU Utilization in Task Manager, where unnecessary Tray items, Startups, Processes and Services that contribute to excessive or continued spiking can be disabled.

6th Generation processors introduced "Speed Shift" technology in Windows 10, which responds much faster to changes in workload than "SpeedStep" due to having many more Core speed and Core voltage transition levels.

Since 7th Generation Speed Shift is twice as fast as 6th Generation, some i7 7700K users complain of severe Core temperature spikes which cause fluctuations in fan RPM at idle. Motherboard manufacturers are currently developing BIOS fixes that include separate SpeedStep and Speed Shift settings with more flexible fan curves and time delay options.

Also, trying to sense thermal performance by touch is like trying to guestimate the temperature of a campfire from 20 meters away. Since hundreds of millions of nanometer scale transistors are densely packed into a tiny Die, heat dissipates throughout the Package over a relatively large area and thermal gradient to the cooling surface, about 3 millimeters from the heat source (1 millimeter = 1,000,000 nanometers).

Even at 100% workload nothing will feel hot; exhaust airflow, cooling fins, heat pipes or water blocks will feel warm, and liquid cooling hoses will have a moderate temperature differential.

Once again, welcome aboard!

The temp is 10c above what I'd expect and what I see on mine at stock clocks with NH-D15 Noctua, given 23c ambient anway...

mdd1963 :

my ambient is around 30

hrvojevlahovic :

Mine idles at 30 and maxes out at 65-70, so yours is absolutely fine.

hrvojevlahovic :

Although Throttle temperature (Tj Max) is 100°C, Core temperatures above 85°C aren't recommended.

Here's the operating range for Core temperature:

Core temperatures increase and decrease with Ambient temperature.

hrvojevlahovic :

Here's the temperature conversions and a short scale for Ambient temperature:

Considering that you're running a ThermalTake Riing Silent 12 Pro in a high Ambient environment (30°C / 86°F), your Core temperatures are marginal, but still OK.

10 or 15 days more then ambient come on around 20

speed shift cause problems i turn off on bios

and playing bf1, 2-3 h and my temp not go above 77

hrvojevlahovic · Aug 16, 2017

intel hyper threating cause my problems with temp.

i turn off and playing BF1 2-3h on ambient 27

and my max temp. not going above 77

Hyperthreading is the primary reason why i7's run hotter than i5's, by as much as 10°C.
