Want to know how to check laptop temperature in Celsius (°C)? Your laptop has built-in sensors that track heat from its processor, graphics chip, and other components. You can read these temperatures using Windows tools, monitoring software, or your laptop’s BIOS/UEFI settings.
The key is knowing which temperature you are checking and whether the laptop is idle, browsing, gaming, or running demanding software.
Quick Answer
On Windows, press Ctrl+Shift+Esc, open Performance, and select GPU to see its temperature in °C if supported. Task Manager does not show CPU temperature. For CPU readings, use HWMonitor or Core Temp. BIOS/UEFI may also display temperatures before Windows starts. Compare readings during light and demanding tasks to identify possible overheating.

How Can You Check Laptop Temperature?
You can check laptop temperature through Windows Task Manager, a dedicated monitoring app, or BIOS/UEFI. The best method depends on whether you need the CPU temperature, GPU temperature, or a general picture of system heat.
Method 1: Check GPU Temperature in Windows Task Manager
Windows can show the temperature of a supported dedicated graphics processor without installing additional software. This is particularly useful when investigating heat during gaming or graphics-intensive work.
- Press Ctrl + Shift + Esc to open Task Manager.
- Select Performance from the sidebar or tab.
- Choose the GPU entry from the list of hardware components.
- Look for the GPU temperature, normally displayed in Celsius (°C).
- If your laptop has multiple GPUs, check each available entry.
The temperature field may not appear on laptops with integrated graphics or unsupported drivers. Microsoft’s GPU temperature guidance explains the hardware and driver requirements for this feature.
Important: Task Manager shows CPU usage, speed, and other performance information, but it does not provide a standard live CPU-temperature reading.
Method 2: Check CPU Temperature Using Monitoring Software
A hardware-monitoring utility is the simplest option when you need live CPU temperatures while Windows is running. Depending on the program and hardware, it may also report GPU, storage, and fan information.
- Download a reputable monitoring utility from its official website.
- Install or launch the program following its instructions.
- Find the CPU or processor section.
- Look for temperature entries such as Core Temperatures or CPU Package.
- Read the current temperature in °C and note any minimum or maximum values.
- Repeat the check during your normal workload to see how temperatures change.
A CPU Package reading represents a processor-level measurement, while individual core readings show temperatures from separate CPU cores. These values do not always match.
For a cleaner baseline, enter BIOS or UEFI at startup; many firmware panels display direct thermal readings before the OS loads.
For an accurate comparison, monitor the laptop under similar conditions each time. Note the workload, room temperature, and whether the laptop is plugged into power.
Which Apps Show Laptop Temperature Best?
HWMonitor and Core Temp are practical choices for checking laptop CPU temperature. HWMonitor provides broader hardware data, while Core Temp focuses on processor cores. Other utilities may be better for gaming overlays or a simple system overview.
These applications offer different levels of detail, so choose one that matches the component you want to inspect.
| App | Best use |
|---|---|
| HWMonitor | CPU and GPU temperatures, voltages, fan speeds, and supported storage sensors |
| Core Temp | Individual CPU core temperatures and processor-focused monitoring |
| Speccy | General hardware information and supported component temperatures |
| MSI Afterburner | GPU temperature, performance graphs, and gaming overlays |
| Open Hardware Monitor | Open-source monitoring of supported sensors, fans, voltages, and temperatures |
HWMonitor: Best for Detailed Hardware Readings
HWMonitor from CPUID reads supported temperature, voltage, power, and fan sensors. It can also display storage and battery information when those sensors are available.
Open the application, expand your processor entry, and look for Temperatures. Check the current reading first, then compare it with the minimum and maximum values recorded during the monitoring session.
Core Temp: Best for CPU Temperature
Core Temp displays processor temperature information, including individual core readings on supported CPUs.
It is useful when you want to observe how each CPU core responds to changing workloads. However, it is not a complete replacement for a tool that monitors the laptop’s GPU, storage, and other components.
Speccy and Open Hardware Monitor: General System Monitoring
Speccy provides a straightforward hardware overview and displays temperatures for supported components. It suits readers who want system specifications and basic thermal information in one place.
Open Hardware Monitor offers a sensor-focused approach, including CPU, GPU, and fan information where supported. Its compatibility may vary with newer laptop hardware, so missing data does not automatically mean that a sensor has failed.
MSI Afterburner: Best for Monitoring Temperatures While Gaming
MSI Afterburner is useful for watching GPU temperature, utilization, and other performance metrics during games. It can display selected readings over the game through an on-screen overlay.
According to MSI’s monitoring guide, you can open Settings, select Monitoring, choose the statistics you want, and enable their on-screen display. RivaTuner Statistics Server is needed for this overlay feature.
Not every sensor or fan-control feature works on every laptop. Manufacturer firmware may control the cooling system independently of the monitoring application.
Can You Check Laptop Temperature in BIOS?
Yes, many laptops can display CPU or system temperatures inside BIOS or UEFI firmware. This method works before Windows loads, making it useful when the operating system is unstable or you do not want to install a monitoring application.
However, not every laptop BIOS provides temperature readings. The available information depends on the manufacturer, model, and firmware design.
How to Enter BIOS and Find Temperature Readings
- Save your work and restart the laptop.
- During startup, press the BIOS entry key shown on the screen. Common keys include F2, F10, Delete, and Esc.
- Once BIOS or UEFI opens, look for Hardware Monitor, PC Health, Monitor, Advanced, or Diagnostics.
- If temperature sensors are available, read the CPU or system temperature displayed in °C.
- Exit without changing settings unless you understand what those settings do.
Some laptops enter BIOS through a startup menu rather than a single direct key. For example, many Dell laptops use F2, while HP models often use Esc followed by F10.
Many BIOS menus display CPU and system temperatures under the main screen, Hardware Monitor, PC Health, or similar sections.
How to Open UEFI from Windows 11
If your laptop uses UEFI firmware, Windows 11 provides another way to access its settings.
- Open Settings.
- Select System > Recovery.
- Under Advanced startup, select Restart now.
- Choose Troubleshoot > Advanced options.
- Select UEFI Firmware Settings and then Restart, if the option is available.
These steps follow Microsoft’s UEFI access instructions. The option may be unavailable on certain systems or firmware configurations.
A BIOS temperature is only a snapshot under firmware conditions. It does not show how hot the processor becomes during gaming or video editing inside Windows. Firmware and Windows power-management behavior may also differ.
If BIOS does not show any temperature field, use supported monitoring software instead.
What Is a Normal Laptop Temperature?
A normal laptop temperature depends on the processor model, workload, room temperature, and cooling system. Light work often produces much lower readings than gaming or rendering, but there is no single safe temperature range for every laptop.
The original guide’s broad ranges of 30°C to 50°C for light use and 70°C to 90°C under heavy load can serve as rough examples, not universal limits.
| CPU Temperature | Typical Situation | What It Means |
|---|---|---|
| 30°C–50°C | Idle or light work on some laptops | Often comfortable thermal conditions, though a higher idle reading can still be normal. |
| 70°C–90°C | Gaming, rendering, or demanding applications | Commonly seen under heavy load; compare with your specific processor’s specifications. |
| Above 90°C | High sustained demand or a possible cooling concern | Not automatically overheating. Check the CPU’s rated limit, throttling, and system stability. |
These are illustrative ranges rather than manufacturer-approved limits. Intel’s idle-temperature guidance explains that CPU temperatures vary with cooling, surroundings, and applications. It notes that package idle temperature is generally below 65°C in typical system designs.
Is 90°C Too Hot for a Laptop?
Not necessarily. Some high-performance laptop processors are designed to operate at elevated temperatures during demanding workloads.
Intel explains that its processors have model-specific thermal limits, with maximum junction temperatures commonly ranging from 100°C to 110°C. Your laptop’s actual limit may differ because of its processor and manufacturer settings.
Check the processor’s exact specification using Intel’s thermal specifications guidance, or the equivalent documentation for your processor.
When a processor approaches its thermal limit, it may reduce power or clock speed to control heat. This behavior is called thermal throttling.
Watch for a pattern of high temperature combined with severe slowdowns, stuttering, unusually loud fans, instability, or unexpected shutdowns. A brief temperature spike alone does not prove the cooling system is defective.
How to Compare Temperature Readings Correctly
Checking the same sensor under different workloads is more useful than comparing unrelated readings.
- Current: The temperature at the moment you look.
- Minimum: The lowest temperature recorded during the monitoring session.
- Maximum: The highest temperature recorded during that session.
- CPU Package: A processor-level temperature measurement.
- GPU Temperature: A separate measurement from the graphics processor.
CPU core, CPU package, GPU, and motherboard readings may differ even when every sensor is functioning correctly. You should not assume that one sensor’s temperature represents the entire laptop.
How Can You Lower High Laptop Temperatures?
Start by improving ventilation and reducing unnecessary processor load. If your laptop continues running unusually hot, check for dust, fan problems, and cooling-system wear before considering internal repairs.
- Use a hard, flat surface. Keep the laptop on a desk or stand rather than bedding, cushions, or other soft materials that may block air vents.
- Keep vents clear. Check intake and exhaust openings for dust or objects that restrict airflow.
- Reduce background activity. Use Task Manager to identify unnecessary applications consuming CPU resources, then close those you do not need.
- Choose an appropriate power mode. When maximum performance is unnecessary, a balanced or more efficient power profile may reduce heat output.
- Consider a cooling pad. An external cooling pad or USB fan may help some laptops, especially during sustained heavy workloads. Its effectiveness depends on the laptop’s vent layout.
- Check cooling-system maintenance. Persistent high temperatures may indicate clogged internal fans, poor heatsink contact, or degraded thermal paste that requires professional inspection.
Warning: Turn off and unplug your laptop before cleaning it. Avoid pushing objects or liquid into ventilation openings. If internal disassembly or thermal-paste replacement is needed, consult a qualified technician or the manufacturer’s service instructions.
How Do You Know Whether Cooling Improvements Worked?
Run the same normal task before and after your cooling changes, then compare the same temperature sensor. Keep the power settings and surrounding conditions as consistent as practical.
Look for more stable temperatures, fewer slowdowns, and normal fan behavior. The goal is reliable performance within your laptop’s designed thermal limits, not forcing every processor to remain below an arbitrary number such as 85°C.
If temperatures remain unusually high, fans stop working, or the laptop shuts down unexpectedly, seek professional service rather than repeatedly running demanding tasks.
Frequently Asked Questions
