periodic temperature increases during operation
When I run stress tests on my CPU, I notice regular temperature increases and high DPT values. This pattern repeats even during regular use, making it tougher to confirm and assess with varying workloads. The attached image displays the temperature curve during stress testing with IETU. Temperatures fluctuated between 62 and 82 degrees with an OC of 5GHz and spikes occurred every two seconds. My system is an ASUS Rogo Maximus X Hero, 8700K, 32GB RAM. The OC examples were [email protected], [email protected], and default settings. Cooling appears to be handled by a NZXT Kraken X62. These adjustments didn’t eliminate the regular spikes, only shifted the temperature range. I’ve also tried reapplying thermal paste in hopes of resolving the issue.
glazor,
On behalf of Tom's Moderator Team, welcome to the team!
IETU experiences varying workloads, which explains the changing Core temperatures you're observing. Running a consistent load will yield more stable readings.
The "Charts" in SpeedFan display 13 minutes of data, illustrating how each benchmark produces unique thermal patterns.
Displayed from left to right: Prime95 Small FFT, Blend, Linpack, and IntelBurn Test.
Observe the consistent thermal pattern of the Small FFTs, enabling precise Core temperature measurements.
Maintaining a full 100% workload is essential for effective thermal testing, allowing the CPU, cooler, socket, motherboard, and voltage regulators to reach stable operating temperatures.
Glazor, On behalf of Tom's Moderator Team, we’re pleased to have you here! IETU experiences variable workloads, which explains the changing Core temperatures you observe. Running a consistent load will yield more stable readings. The "Charts" in SpeedFan cover a 13-minute duration, illustrating how each benchmark produces unique thermal patterns. Displayed from left to right: Prime95 Small FFT's, Blend, Linpack, and IntelBurn Test. Observe the consistent thermal pattern of the Small FFT's, which ensures precise Core temperature readings. Maintaining a uniform 100% workload is essential for effective thermal evaluation; this allows the CPU, cooler, socket, motherboard, and voltage regulators to reach stable operating temperatures. Shown above from left to right: Prime95 Small FFT's, Intel Extreme Tuning Utility CPU Test, and AIDA64 CPU Test. "Stress" evaluations differ significantly and can be divided into two types: stability tests with changing loads, and thermal tests with constant loads. Prime95 v29.8 Small FFT's (AVX disabled) is particularly effective for thermal performance assessment, as it aligns with Intel’s specifications for a stable 100% workload yielding consistent Core temperatures. No other tool matches Intel’s thermal benchmarking needs. Software that avoids overloading or underloading the processor will provide a reliable thermal reference. Below is a comparison of tools categorized by thermal and stability tests, based on TDP percentage, averaged across six processor generations at default settings, rounded to the nearest 5%: Although these evaluations span from 70% to 130% TDP, Windows Task Manager interprets each test as 100% CPU usage, which reflects processing activity rather than actual workload. Core temperatures directly reflect power draw (Watts), which is influenced by the current load. Prime95 v29.8 Small FFT's (AVX disabled) delivers a stable 100% workload, even when TDP exceeds normal limits through overclocking. Ensure Core temperatures stay below 85°C to guarantee your CPU handles demanding real-world tasks without overheating.
