Check CPU temperature in BIOS/UEFI (enter BIOS during boot and view Hardware Monitor/PC Health)
Use Windows Task Manager (Performance tab → CPU → view temperature if available)
Install and use a CPU temperature monitoring tool (HWMonitor, Core Temp, HWiNFO, SpeedFan)
Check temperatures in HWiNFO or similar tools (look for “CPU Package” / “CPU Core” / “Tctl/Tdie”)
Verify readings via manufacturer software if available (Intel Extreme Tuning Utility, AMD Ryzen Master)
Monitor hotspot/maximum temperature values (Core temps vs package temp)
Stress test briefly to confirm cooling performance (run a short CPU load test and watch peak temps)
Check cooler and fan operation (CPU fan RPM in BIOS/HW monitor; confirm fans spin under load)
Inspect airflow and heatsink contact (ensure heatsink is seated; confirm dust is cleaned)
Review thermal throttling indicators (reduced clocks, performance drops, or “thermal throttling” flags in monitoring tools)
Confirm ambient room temperature and case airflow (temperature rise can indicate insufficient cooling)
Re-check after changes (reapply thermal paste if needed; compare temps before/after)
Set alerts for high temperatures in monitoring software (warning/critical thresholds)
