The outside surface is not a reliable controller temperature sensor Thermal checkpoint 1 needs telemetry under repeatable conditions Measure idle temperature after the machine settles, then capture load temperature during the same benchmark or transfer each time. Use Measure instead of touching the heatsink to evaluate the cooler already present.

Record temperature after a stable idle period and again during a repeatable workload Thermal checkpoint 2 needs telemetry under repeatable conditions Measure idle temperature after the machine settles, then capture load temperature during the same benchmark or transfer each time. Use Establish idle and load baselines to evaluate the cooler already present.

Thermal throttling is a performance-protection behavior Thermal checkpoint 3 needs telemetry under repeatable conditions Measure idle temperature after the machine settles, then capture load temperature during the same benchmark or transfer each time. Use Check whether speed falls as heat rises to evaluate the cooler already present.

Seagate states that the pre-installed heatsink should not be removed because doing so can damage the SSD Thermal checkpoint 4 needs telemetry under repeatable conditions Measure idle temperature after the machine settles, then capture load temperature during the same benchmark or transfer each time. Use Keep the factory 530R heatsink intact to evaluate the cooler already present.

A bare NVMe SSD in a high-performance Gen4 workload benefits from competent motherboard or aftermarket M.2 cooling and case airflow Thermal checkpoint 5 needs telemetry under repeatable conditions Measure idle temperature after the machine settles, then capture load temperature during the same benchmark or transfer each time. Use Verify bare-drive cooling to evaluate the cooler already present.

Adding a second cooler over a factory-heatsink model can impair fit and thermal contact instead of improving cooling Thermal checkpoint 6 needs telemetry under repeatable conditions Measure idle temperature after the machine settles, then capture load temperature during the same benchmark or transfer each time. Use Avoid stacking heatsinks to evaluate the cooler already present.

An M.2 slot directly beneath a high-power graphics card may experience a different thermal environment from an open motherboard test bench Thermal checkpoint 7 needs telemetry under repeatable conditions Measure idle temperature after the machine settles, then capture load temperature during the same benchmark or transfer each time. Use Check nearby GPU heat to evaluate the cooler already present.

Dust, blocked intake paths and stopped fans can raise local temperatures Thermal checkpoint 8 needs telemetry under repeatable conditions Measure idle temperature after the machine settles, then capture load temperature during the same benchmark or transfer each time. Use Clean airflow without overreacting to evaluate the cooler already present.

A drive can be slow because it is on Gen3, sharing lanes, or copying from a slower disk even if its temperature is perfect Thermal checkpoint 9 needs telemetry under repeatable conditions Measure idle temperature after the machine settles, then capture load temperature during the same benchmark or transfer each time. Use Distinguish temperature from firmware or link issues to evaluate the cooler already present.

High temperature plus I/O errors, timeouts or disappearance deserves a cautious backup-first approach Thermal checkpoint 10 needs telemetry under repeatable conditions Measure idle temperature after the machine settles, then capture load temperature during the same benchmark or transfer each time. Use Protect data if heat accompanies errors to evaluate the cooler already present.
