Just as our brains require optimal conditions to function smoothly, the Central Processing Unit (CPU) of a computer also operates best when kept cool. Overheating can cause performance hiccups, system crashes, or even permanent damage. While numerous software tools exist for monitoring CPU temperature, you can also check it without installing anything new. Understanding the normal CPU temperature range is crucial for maintaining your system’s health and longevity. This guide will walk you through several methods, suitable for both beginners and those with some technical know-how.
Understanding CPU Temperature
Before we dive into the methods, it’s helpful to understand what CPU temperature is and why it matters. The temperature is a measure of how hot the CPU gets during operation. It’s usually measured in degrees Celsius (°C) or Fahrenheit (°F).
A safe temperature range varies depending on the CPU model and manufacturer, but generally, you want to keep it below 80°C (176°F) under load (when the CPU is working hard). Higher temperatures can indicate issues with cooling, airflow, or even a failing CPU.
Method 1: BIOS/UEFI
The Basic Input/Output System (BIOS) or its modern equivalent, Unified Extensible Firmware Interface (UEFI), is firmware that initializes your computer’s hardware during startup. Most BIOS/UEFI setups include temperature readings for various components, including the CPU.
- Restart your computer.
- Press the designated key to enter BIOS/UEFI. This key is often displayed on the screen during startup (e.g., Del, F2, F10, or Esc).
- Navigate to the hardware monitoring section. The location may vary depending on your BIOS/UEFI, but look for terms like “Hardware Monitor,” “PC Health Status,” or “System Information.”
- Look for CPU temperature. It should be listed in degrees Celsius or Fahrenheit.
- Exit BIOS/UEFI without saving any changes.
Method 2: Command Prompt/PowerShell
For Windows users, the Command Prompt or PowerShell offers a way to query CPU temperature data directly from the system.
Command Prompt:
- Open Command Prompt as Administrator.
- Type wmic /namespace:\\root\wmi PATH MSAcpi_ThermalZoneTemperature get CurrentTemperature and press Enter.
- The temperature will be displayed in Kelvin. To convert to Celsius, subtract 273.15 from the value.
PowerShell:
- Open PowerShell.
- Type Get-WmiObject MSAcpi_ThermalZoneTemperature -Namespace “root/wmi” and press Enter.
- Similar to the Command Prompt, the temperature is in Kelvin.

Method 3: Hardware Monitoring Chips
Some motherboards have dedicated hardware monitoring chips that provide temperature readings for various components. You might be able to access this data through:
- Dedicated software: Some motherboard manufacturers offer software to display readings from the hardware monitoring chip.
- Third-party software: Tools like HWMonitor or SpeedFan can access data from various hardware monitoring chips.
Important Note: While these methods can give you a good idea of your CPU temperature, they might not be as accurate or comprehensive as dedicated software tools. If you’re frequently concerned about your CPU temperature or notice it consistently running hot, it’s recommended to use a reputable temperature monitoring program for more in-depth analysis and alerts.
Additional Tips:
- Clean your computer regularly: Dust buildup can hinder airflow and lead to higher temperatures.
- Ensure proper ventilation: Make sure your computer has enough space around it for air to circulate.
- Consider additional cooling: If your CPU runs hot even after cleaning and ensuring ventilation, you might need to upgrade your CPU cooler.
I hope this guide helps you keep your CPU cool and running smoothly!
