How to Check CPU Temperature in Windows 11 (Without BIOS) – Simple Guide for Beginners

Your CPU (the brain of your computer) generates heat when it works, just like your body does when you exercise. But unlike your body, your computer can’t tell you when it’s uncomfortable.

If your CPU temperature gets too high, your system can slow down, freeze, or even shut down suddenly to protect itself. Over time, overheating can reduce performance, shorten your hardware’s lifespan, and cause unexpected crashes, especially during gaming, video editing, or other heavy tasks. In this article, you’ll learn how to check CPU temperature on your PC, what temperatures are normal, and simple ways to reduce heat and keep your system running smoothly.

What Is a Safe CPU Temperature? (Normal vs High)

Your CPU temperature can change depending on what you’re doing idle, browsing, or heavy tasks like gaming. But there are safe limits you should know to avoid overheating problems.

Different processors have different limits, but you can use these general guidelines:

• Idle/light use (browsing, documents): 30°C – 50°C (86°F – 122°F)
• Gaming or heavy work (video editing, rendering): 60°C – 80°C (140°F – 176°F)
• Risky area: Above 85°C (185°F) for long periods
• Too hot/dangerous: 95°C (203°F) and above

For exact limits, you can also check the official temperature specifications from your CPU manufacturer.

• Intel: https://www.intel.com (specific CPU product spec page for Tjunction / max temp)
• AMD: https://www.amd.com (specific processor specs page)

Your CPU is designed to protect itself. If it gets too hot, it will slow down automatically or even shut down the PC to avoid damage.

Signs your CPU might be running too hot:

• Fans are loud all the time
• PC feels slow even in simple tasks
• Games stutter or crash
• The computer suddenly turns off under load

If you see any of these, it’s a good idea to check your CPU temperature.

How to Check CPU Temperature on Windows 11

Windows 11 doesn’t show CPU temperature directly in Settings, but you can still check it with a few simple methods.

Method 1: Check CPU Temperature from BIOS/UEFI (Basic Way)

BIOS/UEFI is a built‑in menu that appears before Windows starts. Many motherboards show the CPU temperature there.

Steps to check CPU temperature in BIOS/UEFI

Option 01:

1. Press Windows + i to open Settings.
2. Select System from the left sidebar.
3. Click Recovery on the right.
4. Under Advanced Startup, click Restart Now and confirm.
5. After the restart, go to Troubleshoot > UEFI Firmware Settings and click Restart.
6. In BIOS/UEFI, look for CPU Core Temperature or a similar setting under the main or advanced tabs.

Option 02:

1. Restart your PC.
2. As soon as it starts booting, press the setup key a few times. Common keys are: Del, F2, F10, or Esc. (Your screen may briefly show “Press DEL to enter Setup” or similar.)
3. Once you are in the BIOS/UEFI menu, look for a section like:
   • Hardware Monitor
   • PC Health Status
   • H/W Monitor or System Health
4. In that menu, you should see CPU Temperature, usually in °C (Celsius).

Note: This method shows temperature at idle (not during normal use)

If you want to monitor CPU temperature in Windows 11 or 10 without opening the BIOS every time, use the next method.

Method 2: Check CPU Temperature in Windows 11/10 (Without BIOS)

To see CPU temperatures while you use your PC, the easiest way is to install a small, free monitoring tool. These tools read data from the sensors on your CPU and motherboard.

Below are a few trusted tools and how to use them.

Option 1: Using Core Temp (simple and lightweight)

Core Temp is a small app that shows the temperature of each CPU core.

How to use Core Temp:

1. Go to the official Core Temp website and download the installer.
2. Run the installer and follow the on‑screen steps. If it offers extra bundled software, uncheck those boxes.
3. Open Core Temp after installation.
4. In the main window, you’ll see:
   • Your CPU model
   • Current temperature of each core
   • Minimum and maximum temperatures
5. By default, Core Temp can also show CPU temperature in the system tray (bottom‑right corner of the screen). This lets you see it while you work or play games.

This is one of the best tools if you want a small, simple app just to watch temperatures.

Option 2: Using HWMonitor (more detailed information)

HWMonitor shows not only CPU temperature, but also:

• Motherboard temperatures
• Fan speeds
• Voltages
• Sometimes GPU temperature

How to use HWMonitor:

1. Download CPUID HWMonitor from the official website.
2. Choose the installer or portable version (the portable version doesn’t require installation).
3. Open HWMonitor.
4. In the main window, look for your CPU name under the list.
5. Under that, you’ll see:
   • Temperatures for each core
   • Current, minimum, and maximum values

HWMonitor is useful if you want a full picture of what’s happening inside your PC.

Option 3: Using Open Hardware Monitor (free and open-source)

Open Hardware Monitor is a free, open‑source tool that shows temperatures, fan speeds, and more.

How to use Open Hardware Monitor:

1. Download Open Hardware Monitor from its official website.
2. Extract the ZIP file.
3. Run the OpenHardwareMonitor.exe file.
4. In the main window, expand the CPU section.
5. You’ll see the temperature for each core, plus minimum and maximum values.

You can also choose to show temperatures in the system tray for quick access.

Option 4: Using Speccy (simple overview of your whole PC)

Speccy gives you an easy overview of your whole system: CPU, RAM, storage, and temperatures.

How to use Speccy:

1. Download Speccy from the official site.
2. Install and open the program.
3. On the main screen, you’ll see a summary with your CPU temperature.
4. You can click CPU on the left to see more details.

Which CPU Temperature Tool Should You Use?

If you’re not sure which one to install, here’s a simple way to choose:

• Just want a small tool to see CPU temperature?
  Use Core Temp.
• Want to see more details like fans and voltages?
  Use HWMonitor or Open Hardware Monitor.
• Want a simple overview of your whole PC?
  Use Speccy.

All of these tools are free and widely used by PC users.

Pro Tip: Keep a temperature monitor running while gaming or heavy tasks to see how hot your CPU gets under load.

Note: Your CPU temperature is a problem if:

• It's above 90°C during normal tasks (browsing, email)
• It's consistently above 85°C even when you're not gaming
• Your computer is shutting down randomly
• You hear loud fan noise but the computer is still hot
• Performance drops suddenly when the computer gets warm

What to Do If Your CPU Is Still Too Hot

How to Reduce CPU Temperature (Fix Overheating Issues)

If your CPU temperature is often above 80–85°C during normal use or gaming, try these simple tips.

1. Clean dust from your PC

Dust can block fans and vents, trapping hot air inside.

• Turn off your PC and unplug it.
• Open the side panel (for a desktop).
• Use compressed air or a soft brush to gently remove dust from:
  • CPU cooler
  • Case fans
  • Power supply vents

If you have a laptop, carefully clean the outside vents with compressed air.

2. Improve airflow

Your PC needs fresh air coming in and hot air going out.

• Make sure the air vents are not blocked.
• Don’t push your PC right against a wall.
• Avoid placing a laptop on soft surfaces like beds or pillows. Use a hard, flat surface.

You can also add more case fans in a desktop to improve airflow.

3. Check or reapply thermal paste

Between the CPU and its cooler, there is a small layer of thermal paste that helps move heat away from the CPU.

• Over time, this paste can dry out or be applied poorly.
• If you are comfortable opening your PC and working with hardware, you can clean off the old paste and apply new, good-quality thermal paste.
• If not, it’s better to take it to a technician.

4. Adjust fan speeds

Some motherboards and tools let you control fan speeds.

• In BIOS/UEFI, look for a fan control or Q‑Fan setting.
• Some brands offer their own software (for example, ASUS AI Suite, MSI Center, etc.).
• You can create a more aggressive fan curve so fans spin faster when the CPU gets hot.

Faster fans mean better cooling, but also more noise. Find a balance that works for you.

5. Close heavy background apps

Too many apps running in the background can increase CPU load.

• Press Ctrl + Shift + Esc to open Task Manager.
• Go to the Processes tab.
• Sort by CPU to see which apps are using the most power.
• Close apps you don’t need, especially browsers with many tabs, game launchers, or background updaters.

6. Reduce or disable overclocking

If you have overclocked your CPU for higher performance, it will naturally run hotter.

• Try going back to default settings in BIOS/UEFI.
• Test your temperatures again.
• You may lose a little performance but gain a cooler and more stable PC.

Conclusion:

Keeping your CPU temperature under control is essential for maintaining your PC’s performance and lifespan. Overheating can lead to slowdowns, crashes, and even long-term hardware damage, but the good news is, it’s easy to monitor and fix.
