How to View Current Bios Temperature: Step-by-Step Guide

You can check CPU temperature in BIOS or UEFI without installing any software. The firmware’s hardware monitor shows your processor’s current temperature and may also display cooling fan speeds. This helps you spot possible cooling problems before Windows starts, although it cannot measure temperatures during gaming or other demanding tasks.

How to Check CPU Temperature in BIOS: Step by Step

The simplest way to check your CPU temperature is to open your computer’s BIOS or UEFI setup. Most desktop motherboards provide a hardware-monitoring screen, although some laptops and prebuilt computers do not.

Follow these steps:

1. Save your work. Close open programs because you will need to restart the computer.
2. Restart your PC. As the manufacturer logo appears, repeatedly tap the setup key, usually Delete or F2. Some computers use Esc, F10, or another key.
3. Open the hardware-monitoring menu. Look for Hardware Monitor, Monitor, PC Health Status, System Health, or a similar option.
4. Find CPU Temperature. Read the number displayed in degrees Celsius (°C). Some boards also show CPU Package Temperature.
5. Check cooling information. If available, note the CPU fan speed and motherboard temperature alongside the CPU reading.
6. Exit without saving. Use the firmware’s Exit or Discard Changes option if you only viewed information.

For example, a displayed value of 45°C means the CPU is operating at 45 degrees Celsius at that moment. The reading may change while you remain on the monitoring screen.

BIOS monitoring works before the operating system loads. It is especially useful for checking whether the CPU becomes unusually hot shortly after startup.

How to Enter Your BIOS or UEFI Setup

You can enter BIOS using a startup key or the recovery options built into Windows. The best method depends on your computer’s manufacturer and firmware configuration.

BIOS stands for Basic Input/Output System. UEFI, or Unified Extensible Firmware Interface, is the newer firmware system used by most modern PCs. Both provide access to hardware and startup settings.

Common startup keys include:

• Delete: Common on desktop motherboards.
• F2: Common on laptops and many desktop systems.
• Esc: May open a startup menu with an option for BIOS setup.
• F10: Used for BIOS setup on some computers.
• F12: Often opens a boot menu rather than BIOS directly.

For example, Dell’s BIOS setup instructions confirm that F2 opens firmware settings, while F12 can provide a separate boot menu.

If the setup key does not work, use Windows to enter UEFI:

1. Open Settings in Windows 11.
2. Select System, then Recovery.
3. Find Advanced startup and select Restart now.
4. After restarting, choose Troubleshoot.
5. Open Advanced options.
6. Select UEFI Firmware Settings, then Restart.

These steps follow Microsoft’s Windows Recovery Environment guidance. In Windows 10, Recovery is found under Settings > Update & Security.

If UEFI Firmware Settings is missing, your system may use legacy BIOS mode or may not expose that recovery option. Use the manufacturer’s startup key instead.

Once inside the firmware, avoid changing security, boot, voltage, or processor settings just to view temperatures. Viewing the hardware monitor does not require configuration changes.

Where Is the Hardware Monitor Screen in BIOS?

The hardware-monitoring screen displays available sensor readings from your CPU, motherboard, and cooling system. Its name and location depend on the motherboard manufacturer.

Look for these common menu names:

• Hardware Monitor: Often used in MSI firmware.
• Monitor: Common in ASUS UEFI interfaces.
• PC Health Status: Found in some traditional BIOS menus.
• H/W Monitor: Another name for system hardware monitoring.
• System Health or Smart Fan: May contain temperature and fan information.

According to the MSI BIOS manual, the advanced firmware interface includes a Hardware Monitor section for cooling-related controls.

Some UEFI interfaces display the CPU temperature directly on the main dashboard or EZ Mode screen. Others require you to switch to Advanced Mode.

Use the mouse if supported, or navigate with the arrow keys and Enter. Check the help text or menu labels if the layout differs from these examples.

Once you find the monitoring section, you may see CPU temperature, system temperature, voltages, and fan speeds listed together.

How to Read the Current CPU Temperature

The CPU temperature is usually displayed as a number followed by °C. For example, CPU Temperature: 42°C means the processor is currently reporting 42 degrees Celsius.

Some firmware interfaces also provide Fahrenheit readings, fan speeds in revolutions per minute (RPM), and other sensor values.

Understand Live BIOS Readings

Most hardware-monitoring screens update temperature values while you are viewing them. They are not necessarily fixed readings captured only when BIOS opens.

However, BIOS cannot record how hot the CPU becomes during a Windows game or application. It only measures the processor while the firmware interface is running.

Some motherboards include extra sensor information, such as stored minimum or maximum values. These features are not available in every BIOS.

If a maximum value appears, check what period or sensor it represents before using it for troubleshooting.

CPU Temperature vs. Motherboard Temperature

BIOS may display several temperatures that describe different parts of your computer. They should not be treated as interchangeable.

• CPU Temperature: A processor-related temperature reported by the firmware.
• CPU Package Temperature: A processor package reading, when supported by the hardware.
• Motherboard or System Temperature: A reading from a sensor associated with the motherboard.
• Chipset Temperature: The temperature of the motherboard chipset, when available.

CPU temperature may change faster than motherboard temperature because the processor responds quickly to changes in power use.

Also, the BIOS CPU reading may not match individual core temperatures shown by Windows monitoring software. Different sensors and reporting methods can produce different values.

Check Whether the Reading Is Stable

After finding the CPU temperature, watch whether it remains reasonably stable or keeps climbing. Small changes are normal, but a rapid, continuing rise can suggest a cooling problem.

Check the fan information nearby if it is available. A running CPU cooler helps move heat away from the processor.

However, a fan reading of N/A does not always mean failure. The cooler may use a different fan header, an external controller, or a pump connection.

When the temperature is unexpectedly high, consider the CPU model, the room temperature, recent workloads, and whether the cooler is functioning correctly.

What Is a Normal BIOS CPU Temperature?

A BIOS CPU temperature of approximately 30°C to 60°C is a common general reference for many properly cooled computers. However, no single range applies to every processor or system.

Compact laptops, powerful desktop CPUs, warm rooms, and different firmware power settings can all affect the displayed temperature.

Typical CPU Temperature Ranges

CPU temperatures depend on where and when you measure them. A BIOS reading should not be compared directly with a temperature captured during a demanding game.

The following ranges are general examples, not official limits for every processor.

For many desktop computers, a BIOS temperature around 40°C to 50°C is unremarkable when cooling works correctly.

A temperature around 60°C may also be normal, especially in a warm environment or soon after restarting from a demanding workload.

These examples help identify unusual behavior. They do not replace the processor manufacturer’s temperature specifications.

Safe Load Temperatures Depend on the CPU Model

A processor can safely operate at temperatures that would be unusually high for another model. The manufacturer’s maximum junction temperature, often called Tjmax or TJMax, is the key reference.

Tjmax is a processor-specific thermal limit. As the CPU approaches that limit, its thermal controls can reduce power or clock speed to manage heat.

According to Intel’s official temperature guidance, the maximum junction temperature varies by processor and is usually between 100°C and 110°C for the products covered by its guidance.

For a different example, the AMD Ryzen 7 7800X3D specifications list a maximum operating temperature of 89°C.

These examples show why it is misleading to say that every AMD processor has a 95°C limit or that every Intel CPU has a 105°C limit.

Some modern processors are designed to run near their thermal limits during heavy workloads. A high temperature alone does not prove the cooling system is defective.

Identify your exact CPU model before deciding whether a sustained load temperature is acceptable.

Warning Signs of CPU Overheating

Unexpectedly high BIOS temperatures deserve closer attention because the processor is not running normal Windows applications at that moment.

Warning signs include:

• CPU temperature rising rapidly and continuing to climb in BIOS.
• Temperature warnings displayed by the motherboard firmware.
• A CPU fan that should be spinning but has stopped.
• Sudden shutdowns or restarts associated with high temperatures.
• Noticeable performance drops caused by thermal throttling.
• Cooling fans running at high speed without bringing temperatures under control.

A BIOS reading near 85°C or 90°C is worth investigating on many systems, particularly when paired with a temperature warning or cooling failure. It is not a universal hardware-damage threshold.

If the CPU is already extremely hot in BIOS, avoid running demanding applications until the cooling problem is understood.

Why BIOS Temperatures Can Look Higher Than Windows

BIOS CPU temperatures sometimes appear higher than Windows idle temperatures because the firmware and operating system manage processor power differently.

Windows can place the CPU into low-power states when it has little work to do. Some firmware environments do not use the same power-saving behavior.

Several factors can explain the difference:

• Power management: The processor may consume more power in firmware than at the Windows desktop.
• Fan behavior: BIOS and Windows may use different cooling or fan-control settings.
• Sensor selection: Firmware and monitoring programs may display readings from different sensors.
• Recent activity: A CPU that was hot before restarting may still be cooling down.
• Room temperature: Warm surrounding air reduces the cooler’s ability to remove heat.

A motherboard sensor also measures a different location from the CPU’s internal thermal sensors. This can explain why CPU and system temperatures are not equal.

A higher BIOS reading does not automatically mean overheating. Compare the CPU’s thermal behavior under similar conditions before deciding that something is wrong.

Use BIOS as a starting check, not as the only test of cooling performance. A Windows monitoring utility provides the additional information needed to understand temperatures under real workloads.

How to Check CPU Temperature in Windows

You can monitor CPU temperature continuously in Windows using dedicated hardware-monitoring software. This is the better method for checking temperatures while gaming, rendering, or running demanding programs.

Windows Task Manager does not provide a standard CPU temperature reading. Pressing Ctrl + Shift + Esc and opening Performance > CPU shows processor activity and related information, but not the CPU’s temperature.

On supported systems, Task Manager may display GPU temperature under Performance > GPU. That reading belongs to the graphics processor, not the CPU.

For CPU temperatures, use one of these tools:

• HWiNFO: Displays detailed CPU, GPU, motherboard, and supported fan sensor information. The Sensors-only view is useful for monitoring temperature changes.
• HWMonitor: Provides a simpler layout with available current, minimum, and maximum temperature readings.
• Core Temp: Focuses on processor temperature and supported per-core readings.
• MSI Afterburner: Can display supported temperature readings, particularly when configured with compatible monitoring components.
• ASUS Armoury Crate: May show processor and cooling information on supported ASUS systems.

The official HWiNFO monitoring utility offers live hardware sensor information and reporting features.

Similarly, CPUID’s HWMonitor reads supported temperature, voltage, power, and fan-speed sensors.

For a simple check with HWMonitor:

1. Open HWMonitor.
2. Expand the section showing your processor.
3. Find the Temperatures category.
4. Look for CPU Package or the relevant processor temperature entry.
5. Compare the current reading with the minimum and maximum values.

For HWiNFO, open the Sensors window and find the CPU-related temperature entries. Some AMD processors may show labels such as CPU (Tctl/Tdie), while supported Intel processors commonly expose CPU Package readings.

Use the same sensor when comparing temperatures over time. Switching between a motherboard CPU sensor and an internal CPU package sensor can make the comparison misleading.

How to Compare Idle and Load CPU Temperatures

Comparing idle and load temperatures shows how effectively your cooling system handles increasing processor activity. BIOS provides a low-workload reference, while Windows monitoring software captures temperatures during actual computer use.

Follow this process:

1. Record the BIOS temperature. Note the reading and whether the cooling fan is operating normally.
2. Check Windows idle temperature. Open HWiNFO, HWMonitor, or Core Temp while no demanding application is running.
3. Run a normal demanding task. Use a game, rendering program, or another application that reflects your usual workload.
4. Record peak and sustained temperatures. Watch the temperature during the task rather than relying only on a brief spike.
5. Compare the results. Check whether the processor stays within its model-specific limits and whether performance remains stable.

For example, a CPU may read 45°C in BIOS, 40°C at the Windows desktop, and 80°C during gaming. That pattern can be normal for a processor designed to handle those load temperatures.

Brief temperature spikes can occur when processor clock speeds rise. Sustained heat, repeated throttling, or unstable performance provides more useful evidence of a potential problem.

Do not deliberately stress-test a system that is already displaying overheating warnings or shutting down from excessive heat.

How to Fix High CPU Temperatures

High CPU temperatures can result from blocked airflow, dust buildup, poor cooler contact, excessive processor load, or cooling hardware problems. Start with simple checks before changing hardware or firmware settings.

If the temperature is unusually high in BIOS, pay particular attention to the cooler and fan system because normal Windows applications are not running.

Try these solutions:

1. Check airflow. Make sure the computer’s intake and exhaust vents are not blocked.
2. Inspect fan operation. Confirm that the CPU cooling fan runs when expected and that its connection is secure.
3. Remove dust. Clean accessible filters, vents, and heatsink areas using an appropriate method for the computer.
4. Reduce unnecessary processor load. Close demanding background programs and check whether CPU usage falls.
5. Inspect the cooler. Look for improper mounting, poor heatsink contact, or signs that the cooling system is failing.
6. Check thermal paste when appropriate. Reapply it if cooler removal, poor contact, or degraded material makes replacement necessary.
7. Consider cooling improvements. If the existing cooler cannot maintain suitable temperatures during normal workloads, a compatible upgrade may help.

If your motherboard reports a CPU overheating error, follow its recommended troubleshooting procedure. For example, ASUS’s CPU over-temperature troubleshooting guide covers fan operation, dust buildup, cooler condition, thermal paste, and excessive processor settings.

The following table summarizes common corrective actions.

Thermal paste does not need replacement on a fixed schedule for every computer. Its condition, installation quality, and the system’s cooling performance matter more than age alone.

For liquid cooling systems, check the pump and radiator fans when possible. A failed pump can cause rapid temperature increases even when case fans are working.

If temperatures remain abnormal after basic maintenance, contact the computer manufacturer or a qualified repair technician. This is especially important when shutdowns continue or the cooler cannot be inspected safely.

How to Recheck CPU Temperature After Cooling Fixes

After correcting a suspected cooling problem, return to BIOS and check whether the CPU temperature has improved. Use similar room conditions for a more meaningful comparison.

You can also check the temperature after the computer has been shut down long enough for the hardware to cool. This helps establish a low-workload reference without leftover heat from a previous gaming session.

To confirm the results:

1. Start the computer and enter BIOS or UEFI.
2. Open the same hardware-monitoring screen used previously.
3. Record the CPU temperature and available fan information.
4. Compare the results with the earlier BIOS reading.
5. Return to Windows and monitor temperatures during normal use.

A lower temperature after cleaning or repairing the cooling system is encouraging, but it does not prove that every overheating problem is fixed.

The final check is stable performance under normal workloads, without repeated temperature warnings, unexpected shutdowns, or excessive thermal throttling.

Frequently Asked Questions

How to See Current CPU Temperature?

You can view current CPU temperature in the BIOS or UEFI hardware-monitoring menu if your computer supports it. In Windows, use a monitoring program such as HWMonitor, HWiNFO, or Core Temp. BIOS works before Windows starts, while monitoring software shows temperatures during normal computer use.

How to Read HWMonitor?

Open HWMonitor and expand the processor section to find temperature readings. The Value column shows the current reading, while Min and Max show the lowest and highest recorded values during monitoring. You can also inspect available motherboard temperatures, fan speeds, and voltages to help identify cooling issues.

How Do I See My Motherboard Temperature?

Open the BIOS hardware-monitoring menu and look for Motherboard Temperature, System Temperature, or a similar label. If the firmware does not display it, check a compatible Windows monitoring utility. The available readings depend on the motherboard’s sensors, so some systems may not provide a separate temperature value.

How to See Temperatures in HWiNFO?

Open HWiNFO and select Sensors-only mode, or open the Sensors window from its main interface. Find the processor section and look for CPU Package, CPU Die, or another supported CPU temperature label. You can monitor current readings and available minimum, maximum, and average values while using Windows.

Why Can’t I Find CPU Temperature in BIOS?

Your BIOS may not include a CPU temperature display, especially on certain laptops and prebuilt computers. Look for Hardware Monitor, Monitor, System Health, or an advanced firmware menu first. If no temperature field exists, use compatible monitoring software in Windows instead. The missing display does not automatically indicate a faulty sensor.

Can BIOS Show CPU Temperature While Gaming?

No, BIOS cannot monitor your CPU while a Windows game is running because you must leave the operating system to enter firmware setup. It shows temperature under BIOS operating conditions instead. To monitor gaming temperatures, use HWiNFO, HWMonitor, or compatible software while the game runs.

Conclusion

Checking CPU temperature in BIOS is a simple way to inspect your processor’s thermal condition before Windows starts. Open the hardware-monitoring menu, record the reading, and check the available cooling information.

For a complete picture, compare that reading with CPU temperatures during normal Windows use. If temperatures are unusually high for your processor or cooling problems appear, inspect airflow and cooler operation before running demanding tasks.
