Temperature is a trend, not a single screenshot.
A drive may be fine at idle and too hot under backup, gaming, rendering or enclosure load. History tells the truth.
Current temperature answers now
The current value tells you the present state, but it may miss the workload that caused yesterday's warning.
Maximum temperature reveals stress
Maximum values expose short periods of heat that users often miss. Repeated peaks suggest airflow, enclosure or workload issues.
SSDs and NVMe can throttle
High controller temperature can reduce performance and increase instability. Cooling pads, heatsinks or better airflow may matter more than software tweaks.
Cooling is prevention
Better airflow, less dust and smarter enclosure placement are low-drama fixes that protect both drives and data.
