Hello I was worried that my CPU temperatures were too high so here we go.
My setup:
Corsair TX650 power supply
gygabite GTX 1070 gaming G1 graphics card
Intel I7 7700 processor (with stock cooler)
Asrock b250 gaming K4 motherboard
I have 3 fans 2 NZXT case fans and 1 Corsair LL120mm series fan (without RGB because I don’t have the box to connect the Corsair fan)
When idle my CPU temperatures are around 37-60 degrees. Usually its 37-38 degrees but sometimes it spikes to 60 when it is processing something. Is this normal?
thebilateraltriangle,
The thermal behavior you've described is normal and expected for 7th, 8th and 9th Generation processors.
Core temperatures respond instantly to changes in load.
Intel’s specification for DTS (Digital Thermal Sensors) 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.
Any software activity will show some percentage of CPU Utilization in Windows Task Manager, where unnecessary Tray items, Startups, Processes and Services that contribute to excessive 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 through 9th Generation Speed Shift is twice as fast as 6th Generation, some users complain of Core temperature spikes which can also cause fluctuations in fan RPM at idle. Motherboard manufacturers are implementing BIOS updates that include separate SpeedStep and Speed Shift settings with more flexible fan curves and time delay options.
Although Tj Max "Thottle" temperature is 100°C for your i7 7700, we know that cooler is better for ultimate stability, performance and longevity. As such, it's prudent to observe a reasonable thermal margin below Throttle temperature (Tj Max).
Here's the nominal operating range for Core temperature:
Core temperatures above 85°C are not recommended.
Core temperatures below 80°C are ideal.
Core temperatures increase and decrease with Ambient temperature. Normal or "standard" is 22°C or 72°F.
Gaming generally averages around 55°C, yet can range from 40°C to 70°C or more, depending on how a particular gaming title allocates CPU / GPU workloads, as well as differences in cooling performance and Ambient temperature.
