Understanding Temperature Monitoring

Temperature monitoring is crucial for maintaining system longevity and performance. Modern CPUs and GPUs can operate safely up to 90-100°C, but sustained temperatures above 80°C can reduce component lifespan.

Thermal throttling occurs when components reduce performance to prevent overheating. You’ll notice frame drops in games or slower rendering times as your CPU or GPU automatically lowers clock speeds.

Different components have ideal temperature ranges:

• CPUs: 60-75°C under load, up to 90°C safe
• GPUs: 70-85°C under load, up to 95°C safe
• VRMs: Should stay below 90°C
• Storage: SSDs below 70°C, HDDs below 50°C
