CPU Thermal Stability Test

A diagnostic tool by Meerkats

Assess Sustained Performance & TIM Health in 60 Seconds

This diagnostic test evaluates whether your CPU can maintain stable performance under continuous thermal load. A rapid performance drop is a common indicator of aging or degraded thermal interface material (TIM), which leads to throttling, higher fan noise, and long-term reliability loss.

Thermal Performance Stability

—

Green: stable heat transfer · Yellow: rising thermal resistance · Red: likely throttling

Runs locally • No temperature access • Safe to stop anytime

Why this test works: Thermal interface degradation does not always raise peak temperature immediately. Instead, it causes faster performance decay under continuous load. This test measures that decay pattern rather than raw temperature.

This test does not read hardware temperature sensors or modify your system. Results are inferred from workload performance behavior.
