To check your CPU temperature on Windows, use third-party apps like Core Temp, HWiNFO, or check your BIOS/UEFI settings.
Here’s a breakdown of the most reliable methods to monitor your CPU temperature on a Windows 11 PC:

1. Use Third-Party Monitoring Tools
These apps give real-time temperature readings and are easy to use:
• Core Temp
• Lightweight and focused solely on CPU temperature.
• Shows per-core temperatures and load.
• Download from Core Temp’s official site
• HWiNFO
• Offers detailed system diagnostics including CPU, GPU, and motherboard sensors.
• Ideal for advanced users or overclockers.
• Download HWiNFO
• CPUID HWMonitor
• Displays voltages, temperatures, and fan speeds.
• Great for a quick overview of system health.
• Download HWMonitor
• Speccy
• User-friendly interface with summary and detailed views.
• Good for general users who want a clean layout.
• Download Speccy

2. Check Through BIOS/UEFI
• Restart your PC and press the BIOS key (usually Del, F2, or Esc) during boot.
• Navigate to the Hardware Monitor or System Health section.
• View CPU temperature directly from the firmware.

3. Use PowerShell (Advanced)
While not ideal for temperature, PowerShell can access some system diagnostics. However, it doesn’t natively show CPU temps without third-party scripts or modules.

What’s a Safe CPU Temperature?
• Idle: 30–50°C
• Under Load (gaming, rendering): 60–85°C
• Critical Threshold: 90°C+ (risk of thermal throttling or damage)
If your CPU regularly exceeds 85°C, consider improving airflow, cleaning dust, or upgrading your cooling system.
