The fastest way to check CPU temperature

Open the Task Manager by pressing Ctrl + Shift + Esc, click the Performance tab, then select CPU from the left sidebar. The temperature appears in the top right corner of the window, labeled as a number in degrees Celsius or Fahrenheit depending on your system settings.

This method works on any Windows 11 machine without installing anything extra. The temperature updates every second or so, so you can watch it change as your computer works harder or rests. If you do not see a temperature reading, your CPU or motherboard may not support this feature — some older or budget processors do not report temperature data to Windows.

Task Manager shows your current temperature only while the window is open. If you want to monitor temperature over time or while playing a game, you will need a separate tool.

Key Takeaways

  • Task Manager's Performance tab shows CPU temperature when ready without installing software, but only while the window is open.
  • If Task Manager does not display temperature, your CPU or motherboard does not support temperature reporting to Windows.
  • Third-party tools like HWiNFO or Core Temp log temperature over time and can alert you if your CPU gets too hot.
  • Normal CPU temperature under light use is 30 to 50 degrees Celsius; above 80 degrees Celsius during gaming or heavy work suggests a cooling problem.
  • High temperatures can slow your computer down automatically to protect the CPU, a process called thermal throttling.

Why you should check your CPU temperature

Your CPU generates heat as it works, and if that heat builds up, your computer slows itself down automatically to cool off. This slowdown is called thermal throttling, and it makes games stutter, video editing lag, and everyday tasks feel sluggish. Checking temperature helps you spot cooling problems before they affect performance.

A CPU that runs too hot for too long can also shorten its lifespan. Most modern processors are designed to shut down automatically if they reach a dangerous temperature, but running near that limit regularly is not ideal. Knowing your temperature lets you catch dust buildup in your cooler, check that fans are spinning, or decide whether you need better cooling before problems get worse.

What temperature is normal

When your computer is idle or doing light work like browsing the web, your CPU should sit between 30 and 50 degrees Celsius (86 to 122 degrees Fahrenheit). During gaming, video editing, or other demanding tasks, temperatures between 60 and 80 degrees Celsius (140 to 176 degrees Fahrenheit) are typical and safe.

Above 80 degrees Celsius during normal use suggests your cooler is not working well. Above 90 degrees Celsius means your CPU is getting too hot and may start throttling. Most CPUs have a maximum safe temperature around 100 degrees Celsius, though they will shut down before reaching it.

Temperature varies based on your cooler type, room temperature, and how hard your CPU is working. A laptop will run hotter than a desktop because it has less space for airflow. An old cooler with dust buildup will run hotter than a clean one. These numbers are guidelines, not hard rules, but they help you spot when something is wrong.

Using third-party tools for detailed temperature tracking

If Task Manager does not show temperature or you want to log temperature over time, read HWiNFO or Core Temp. Both are free, show CPU temperature in real time, and can save a log of temperatures while you game or work. HWiNFO shows more detailed information about your entire system; Core Temp is simpler and lighter on system resources.

read HWiNFO from hwinfo.com or Core Temp from alcpu.com. Install it, open it, and look for your CPU name in the list. The temperature will appear next to it. Both tools let you set alerts so your computer beeps or pops up a warning if temperature climbs above a number you choose.

These tools also show you which CPU cores are hottest, which can help identify if one core is working much harder than the others. That information is useful if you are troubleshooting performance problems or trying to understand why your computer is slow.

Checking temperature while gaming or under load

Task Manager will show temperature while you game, but it takes up screen space and can distract you. Instead, use an overlay tool like MSI Afterburner or the built-in overlay in GeForce Experience (if you have an Nvidia graphics card). These display temperature in a small corner of your game without opening a separate window.

MSI Afterburner is free and works with any graphics card. read it from msi.com, install it, then open the settings and enable the on-screen display. You can choose what information to show and where it appears. GeForce Experience comes with Nvidia drivers, so if you have an Nvidia card, it is already on your computer — open it, go to Settings, and turn on the in-game overlay.

Watching temperature while you game tells you whether your cooling setup can handle your workload. If temperature climbs above 85 degrees Celsius and stays there, your cooler may need cleaning or upgrading. If temperature spikes suddenly, a fan may have stopped spinning.

What to do if your CPU is running too hot

Start by cleaning dust from your cooler and case fans. Dust buildup is the most common cause of high temperatures. Shut down your computer, unplug it, open the case, and use compressed air to blow dust out of the cooler fins and fan blades. Do this outside or in a well-ventilated space because dust will fly everywhere.

Check that all fans are spinning. Open your case while the computer is running and look at the CPU cooler fan and case fans. If any are not moving, they may be stuck or disconnected. A stuck fan can sometimes be freed by gently rotating it by hand, but a broken fan needs replacement.

Make sure your cooler is mounted properly. If you recently moved your computer or opened the case, the cooler may have shifted or the thermal paste between the cooler and CPU may have dried out. Remounting the cooler or replacing the thermal paste is a more advanced fix, but it solves many temperature problems. If you are not comfortable doing this yourself, a computer repair shop can do it quickly.

Frequently Asked Questions

Why does Task Manager not show CPU temperature on my Windows 11 computer?

Not all CPUs or motherboards report temperature to Windows. Older processors and some budget models do not support this feature. Try a third-party tool like HWiNFO instead — it can read temperature from more systems than Task Manager can.

Is 70 degrees Celsius too hot for my CPU?

No. 70 degrees Celsius during gaming or heavy work is normal and safe. Temperatures between 60 and 80 degrees Celsius are typical under load. Worry if you see 85 degrees Celsius or higher during normal use, or if temperature climbs above 90 degrees Celsius.

Can I check CPU temperature on a laptop the same way as a desktop?

Yes, the steps are identical — open Task Manager, go to Performance, and select CPU. Laptop temperatures run higher than desktop temperatures because laptops have less airflow. A laptop CPU at 75 degrees Celsius is normal; a desktop CPU at 75 degrees Celsius during light work suggests a cooling problem.

What does thermal throttling do to my computer?

Thermal throttling slows your CPU down automatically to reduce heat. This makes your computer feel sluggish — games stutter, programs lag, and tasks take longer. It is a safety feature that protects your CPU, but it means your cooling is not keeping up with your workload.

How often should I check my CPU temperature?

Check temperature once when you first set up your computer or after opening the case, then periodically during gaming or heavy work to spot problems early. If temperature is stable and normal, you do not need to check it often. Check again if your computer suddenly feels slow or loud.
