Guys, You should definitely check these sections: Section 10 - Thermal Test Basics Section 11 - Thermal Test 100% Workload Intel Temperature Guide - https://forums.
Just to ensure clarity for our members and audience, Prime95 Small FFT with AVX turned off is particularly effective for evaluating thermal performance. Other tools are more appropriate when assessing stability. Many users don’t realize that Prime95’s high-temperature problems are closely tied to AVX versions. Running Prime95 with AVX activated creates an extremely demanding workload—nearly 130%—which can harm stability and heavily stress your CPU. According to Intel’s specifications, TDP and thermal data are confirmed “without AVX.” The most recent Prime95 release (version 29.8) makes it simple to disable AVX, allowing the Small FFT test to meet Intel’s guidelines for a consistent 100% TDP steady-state load with stable core temperatures. No other software matches Intel’s thermal benchmark requirements as closely. In versions from 27.7 to 29.4, you can disable AVX by adding CpuSupportsAVX=0 in the local.txt file found in Prime95’s directory after the first execution. But since core temperatures remain unchanged at 29.8 without AVX, it’s more straightforward to stick with that version. Alternatively, using 26.6 is also possible as it lacks AVX support.
I use real bench and intel XTU tests regularly. I notice my system stays stable during stress tests but can still crash when running benchmarks. The problem I face now is that my OC remains consistent, yet Assassins Creed Odyssey crashes right away. This only happens with the game, not with other titles. I often have to run at stock clocks to get it working. There are many discussions online about this issue, but I’m not sure it’s directly related to my OC.
It seems you're looking for a rephrased version of this text while keeping its meaning intact. Here it is:
The differences in thermal and stability stress test workloads are significant. Utilities that avoid overloading or underloading your processor provide a reliable thermal baseline. This document compares utilities categorized as thermal and stability tests based on TDP percentage, averaged across six processor generations with stock settings, rounded to the nearest 5%. Although these tests cover workloads from 70% to 130% TDP, Windows Task Manager treats each test as 100% CPU utilization, which reflects processor usage rather than actual workload. Temperatures change directly with power consumption (watts), which is influenced by the workload.
