i5-7600k temp spikes

[Mack Bell]

I have an I5-7600k on an ASUS Maximus Vlll Hero under a Corsair h110i.
Just from opening up Chrome my temps spike up by 15-20c and immediately drops down.

Is this normal?

try changing the thermal paste on the cooler...might solve this problem....

When you start a new task such as Chrome, the cpu will immediately get very busy, increasing the multiplier(if you have implemented speedstep) and the associated vcore.
It is the vcore that increases temperature.
I would not worry so long as the temperatures return to normal.
At idle, I would expect to see a temperature no more than 10-15c. over ambient.
Under full load, 70c. would be ok and 85c would be high.
The cpu will shut down or throttle to protect itself at 100c.

You can monitor vcore and the multiplier with cpu-Z.

As already said, check thermal paste and correct mounting of your H110i on the CPU.

Maybe also take a look at the clock speed your CPU goes at during and after the temperature spike.

Whilst gaming temps never exceed 66c, I just find it odd that under water it will jump 20c just from opening up chrome. From what I understand it should be a gradual increase not a spike.

As geofelt explained, yes.

Mack Bell,

Core temperatures respond instantly to changes in load.

Intel’s specification for Digital Thermal Sensor 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 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 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.
