There's the problem ... wrong version.

Please download and run Prime95 version 26.6. Run Small FFT's for just 10 minutes:

Not all loads are created equal. “Stress” tests vary widely and can be characterized into two categories;
stability tests which are
fluctuating workloads, and
thermal tests which are
steady workloads.
Intel tests their processors at a steady 100% TDP workload to validate Thermal Specifications.
Prime95 version 26.6 Small FFT's is ideal for CPU thermal testing, because it's a
steady 100% workload with
steady Core temperatures. No other utility so closely replicates Intel's workload test conditions.
Utilities that don't
overload or
underload your processor will give you a valid thermal baseline. Here’s a comparison of utilities grouped as
thermal and
stability tests according to % of TDP, averaged across six processor Generations at stock settings rounded to the nearest 5%:

Utilization in Windows Task Manager, which indicates processor resource activity,

workload. Core temperatures respond directly to Power dissipation (Watts), which is driven by workload. Prime95 v26.6 Small FFT’s provides a true and steady 100% workload, so if Core temperatures are below 85°C, then your processor should run the most demanding
real-world workloads without overheating.
4th through 9th Generation i9, i7, i5 and i3 CPU’s have
AVX/2 Instruction Sets. Prime95 versions
later than 26.6 run AVX/2 code on the CPU's Floating Point Unit (FPU), which is an
unrealistic workload at nearly 130% that can cause Core temperatures to run
up to 20°C higher.
Many 6th through 9th Generation motherboards address the AVX problem by providing “offset” adjustments (downclock) in BIOS. -3 (300 MHz) or more may be needed to limit Core temperatures to 85°C. Since 4th and 5th Generation don’t have AVX offsets, you can create a BIOS Profile for gaming, and a downclock Profile for AVX apps such as rendering or transcoding. If you don’t use AVX apps, BIOS should still be configured for it, as certain utilities use AVX for stability testing.
Q: Are you using an AVX offset in BIOS?
AVX can be
disabled in Prime95 versions later than 26.6 by inserting "CpuSupportsAVX=0" into the "local.txt" file in Prime95's folder. However, since Core temperatures will be the same as 26.6, it's easier to just use 26.6.
As per Intel’s Datasheets, TDP and Thermal Specifications are validated “without AVX”.
See page 87, Section 5.1.1 Thermal Considerations, 1st paragraph, 2nd sentence:
8th and 9th Generation Intel® Core™ Processor Families Datasheet, Volume 1 -
https://www.intel.com/content/www/us/en/products/docs/processors/core/8th-gen-core-family-datasheet-vol-1.html
Also, I have analyzed "StressMyPC". Although the CPU test is a steady workload, it's only about 65%, which is relatively light and is slightly less than AIDA64's individual CPU test shown lower left on the scale above. It's inadequate for testing processor thermal performance, and does
not provide a valid thermal baseline. However, what it does provide a false sense of security for users since Core temperatures will be misleadingly low.
