How to check cpu and gpu temp


The importance of monitoring CPU and GPU temperatures cannot be overstated as these components are critical to the efficient operation of any computer system. Overheating of these components can lead to various issues, while keeping your system's components cool provides numerous benefits, including increased system stability and longevity.

Methods to Check CPU and GPU Temperatures

There are several ways to monitor the temperature of your CPU and GPU, ensuring that they are working within the safe limits.

Using BIOS or UEFI

Accessing BIOS (Basic Input/Output System) or UEFI (Unified Extensible Firmware Interface) is one method of checking the temperature of your system's components.

1. Accessing BIOS or UEFI: To enter the BIOS or UEFI, restart your computer and press the appropriate key (usually Delete, F2, F12, or another function key) as it starts up.
2. Locating temperature readings: Once in the BIOS or UEFI, navigate to the hardware monitoring or system health section to find temperature readings for your CPU and possibly your GPU.

Using System Utilities in

Windows also provides two built-in tools for checking system component temperatures.

1. Windows Task Manager: Access the Windows Task Manager by pressing Ctrl + Shift + Esc or right-clicking the taskbar and selecting “Task Manager.” Then, click on the “Performance” tab, and you can see the temperature of your CPU and possibly your GPU as well.
2. PowerShell or Command Prompt: You can also check temperatures using PowerShell or Command Prompt. Type “wmic /namespace:\\root\wmi PATH MSAcpi_ThermalZoneTemperature get CurrentTemperature” in PowerShell or Command Prompt and execute the command. The displayed temperature will be in Kelvin, so you will need to convert it to Celsius or Fahrenheit.

Using Third-Party Monitoring

Third-party software often provides more detailed information on CPU and GPU temperatures and may offer additional monitoring features.

1. HWMonitor: This software provides detailed information on system temperatures, voltages, and fan speeds.
2. MSI Afterburner: Primarily used for GPU overclocking, MSI Afterburner also provides temperature monitoring for GPUs.
3. SpeedFan: This software provides detailed temperature monitoring and allows you to control fan speeds to better manage system temperatures.
4. AIDA64: A comprehensive system monitoring tool, AIDA64 displays temperature readings for both CPUs and GPUs, as well as a wealth of other system information.

Knowing the Ideal and Safe Temperature Ranges for CPUs and GPUs

Understanding typical temperature ranges for CPUs and GPUs is crucial to ensure optimal performance and system longevity.

Typical Temperature Ranges for Performance and Longevity

For most CPUs, a temperature range of 45-65°C is considered ideal under normal operating conditions. For most GPUs, a temperature range of 70-85°C is considered ideal under normal operating conditions.

Factors that Influence the Ideal Temperature

There are several factors that can impact the recommended temperature for your CPU and GPU, including:

1. Ambient room temperature: Higher ambient temperatures will naturally cause higher component temperatures.
2. Computer usage: More demanding tasks, such as or rendering, will increase component temperatures.
3. CPU and GPU models: Different models of CPUs and GPUs have different temperature tolerances and recommended operating temperatures.

Causes of High Temperatures and Potential Solutions

Several factors can cause high CPU and GPU temperatures, and identifying the cause is critical to finding a solution.

1. Dust buildup: Excessive dust can impede your system's cooling capabilities. Cleaning your computer's vents and fans can help lower temperatures.
2. Thermal paste application: Poorly applied or aged thermal paste can result in high temperatures. Reapplying thermal paste may be necessary to improve temperature management.
3. Inadequate cooling: Insufficient cooling solutions, such as fans or heatsinks, can cause high component temperatures. Upgrading to more advanced cooling solutions can help keep temperatures in check.

How to Optimize Your System for Better Temperature Management

Proactive steps can be taken to improve your system's temperature management and prevent overheating issues.

Proper Airflow and Cable Management

A well-organized computer case with proper cable management can improve airflow and subsequently help lower component temperatures.

Regular Maintenance Schedules

Regularly cleaning your computer's fans, vents, and heatsinks can help prevent dust buildup and maintain optimal cooling performance.

Picking the Right Cooling Solution

Choosing the right cooling solution for your system is crucial to temperature management.

1. Air cooling: Air cooling solutions, such as fans and heatsinks, can be affordable and effective for most users.
2. All-in-one liquid cooling: These systems use liquid to transfer heat away from components and can be more effective than air cooling, though they also tend to be more expensive.
3. Custom water cooling loops: These advanced cooling solutions can provide the best performance but are more complex and expensive to set up.


Monitoring CPU and GPU temperatures is vital for protecting the health and performance of your computer system. By understanding the various methods for checking temperatures, identifying potential issues, and maintaining a cool and efficient system, users can ensure their computer operates reliably and efficiently over the long term.


What is the maximum safe temperature for a CPU?

The maximum safe temperature for a CPU is generally around 90-100°C, but it's best to maintain lower temperatures to avoid long-term damage or decreased performance.

What is the maximum safe temperature for a GPU?

The maximum safe temperature for a GPU is generally around 85-95°C, but it's best to maintain lower temperatures to avoid long-term damage or decreased performance.

How often should I clean my computer's fan and vents?

It's recommended to clean your computer's fan and vents at least once every 3-6 months, depending on your environment and computer usage.

How do I know if my cooling solution is sufficient for my system?

Monitor your CPU and GPU temperatures during various workloads. If the temperatures consistently stay within the safe range, your cooling solution is likely sufficient.

Can I use liquid cooling for both my CPU and GPU?

Yes, there are liquid cooling solutions available that can be used for both your CPU and GPU, including all-in-one systems and custom water cooling loops.

Should I buy additional fans to improve my system's cooling?

Adding fans can improve cooling, but it's essential to make sure fans are placed strategically and work together efficiently to create optimal airflow within the computer case.
