Temperature and throttling—why it matters
Heat accelerates chemical wear in NAND and changes fluid behavior in HDD bearings—charts reveal whether you have an airflow problem or a workload problem.
Hard drives and lubricants
Mechanical disks tolerate warm idle temps when airflow exists. Long stretches above official guidance accelerate platter wear and increase error rates—watch weekly averages, not minute-long spikes during downloads.
SSDs and thermal governors
NVMe controllers throttle throughput to stay below junction limits. If sustained writes collapse speed without recovery after cooldown, improve mounting—thermal pads, motherboard heatsinks, or fan curves—not just software tweaks.
Seasonal baselines
A studio PC that gains 6 °C every summer may simply need dust evacuation—not new disks. Log ambient room temperature alongside component telemetry when diagnosing mysterious climbs.
