You realize that AIDA64 Stress CPU is only about 70% workload.

Not all loads are created equal. “Stress” tests 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 that typically runs Core i variants with Hyperthreading and Core 2 processors within +/- a few % of TDP. No other utility so closely replicates Intel's 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%:
Higher TDP tests produce higher Core temperatures. All tests will show 100% CPU
Utilization in Windows Task Manager, which indicates processor resource activity,

workload. Although actual Power dissipation (Watts) varies with Core Speed, Core voltage and workload, Prime95 v26.6 Small FFT’s always provides a steady 100% workload, whether you’re running stock or overlocked.
