This guide will walk you through every method, from built-in tools to powerful software, ensuring you can keep your system cool and running smoothly.
High temperatures can lead to slowdowns, crashes, and even permanent hardware damage. Knowing how to monitor these temps helps you prevent problems before they start. It’s a simple task that can save you a lot of trouble and expense down the line.
How To Check Temps On Pc
There are several reliable ways to check your computer’s temperature. The best method for you depends on your comfort level and whether you need a quick check or ongoing monitoring. We will cover BIOS/UEFI checks, free software tools, and built-in Windows options.
Using The Bios Or Uefi
Your computer’s BIOS (Basic Input/Output System) or its modern successor, UEFI (Unified Extensible Firmware Interface), is the most basic way to check hardware temperatures. This method shows you the temperature before your operating system loads, which is useful for checking baseline temps without any software overhead.
To access the BIOS/UEFI, you need to restart your computer and press a specific key during startup. Common keys are Delete, F2, F10, or F12. The correct key is usually displayed briefly on the screen when you first power on the machine.
Once inside the BIOS/UEFI, navigate using your keyboard. Look for a section labeled “Hardware Monitor,” “PC Health Status,” “System Status,” or something similar. The temperature readings for your CPU and sometimes other components will be listed there.
Remember, the BIOS only shows a snapshot. It won’t help you monitor temperatures while you’re gaming or running demanding software. For that, you’ll need software that runs within Windows.
Using Third-Party Software
Third-party software is the most popular and effective method for monitoring PC temperatures in real-time. These programs provide detailed readings, historical data, and often customizable on-screen displays. Here are the best free options available.
Hwmonitor
HWMonitor by CPUID is a lightweight and extremely popular choice. It provides a comprehensive overview of temperatures, voltages, and fan speeds for almost every component in your system.
- Download and install HWMonitor from the official CPUID website.
- Run the program. It will automatically scan your hardware.
- Look for your CPU name (e.g., AMD Ryzen 7, Intel Core i9) and expand the section.
- Find the “Temperatures” entry. It will show current, minimum, and maximum values.
- Also check temperatures for your GPU (graphics card) and storage drives if listed.
Core Temp
Core Temp is specifically designed for monitoring CPU temperature. It’s excellent because it shows the temperature of each individual core in your processor, which is crucial for modern multi-core CPUs.
- Download Core Temp from its official site and install it.
- Open the program. The main window displays a list of all your CPU cores and their current temperatures.
- You can view minimum and maximum recorded temperatures since you started the program.
- A useful feature is the option to display the temperature in the system tray, so you can always see it.
Msi Afterburner
While known as a graphics card overclocking tool, MSI Afterburner is also a superb hardware monitor, especially for your GPU. It works with all brands of graphics cards, not just MSI.
- Install MSI Afterburner and its included RivaTuner Statistics Server.
- Launch Afterburner. The main gauges show GPU temperature, usage, and clock speed.
- Click the settings gear icon, then go to the “Monitoring” tab.
- Here, you can select which metrics to display in an on-screen overlay while you game or use full-screen applications.
Using Built-In Windows Tools
Windows does not have a dedicated, straightforward temperature monitor. However, you can get some related information through its built-in tools, though they are less direct than third-party software.
Task Manager Performance Tab
The Task Manager can give you clues about thermal throttling, which is when your CPU slows down to reduce heat.
- Right-click your taskbar and select “Task Manager,” or press Ctrl+Shift+Esc.
- Click on the “Performance” tab.
- Select “CPU” from the left-hand menu. Look at the “Speed” reading. If it is significantly below its base or boost clock speed while under load, it may be thermal throttling due to high temperatures.
Windows Powershell Or Command Prompt
For very basic sensor data, you can use a command in PowerShell. This method is not as user-friendly and doesn’t show all components, but it can provide some info.
- Type “Windows PowerShell” in the Start menu search and run it as Administrator.
- Type the command:
Get-WmiObject MSAcpi_ThermalZoneTemperature -Namespace "root/wmi" - This will return a “CurrentTemperature” value. Note that this number is in Kelvin multiplied by 10. To convert it to Celsius, use this formula: (Reported Value / 10) – 273.15.
Checking Specific Component Temps
Different components generate different amounts of heat and have unique safe operating ranges. Let’s break down how to check the temps for each major part.
Cpu Temperature
The Central Processing Unit (CPU) is often the hottest component. Use Core Temp or HWMonitor to check it. Look for the per-core readings or the overall CPU package temperature.
- Idle Temperature: A healthy CPU typically idles between 30°C and 50°C (86°F – 122°F).
- Under Load: When gaming or rendering, temperatures between 70°C and 85°C (158°F – 185°F) are common for many CPUs. Consistently hitting 90°C+ (194°F+) is a cause for concern and may indicate a cooling problem.
Gpu Temperature
Your Graphics Processing Unit (GPU) works hard during games and creative tasks. MSI Afterburner or HWMonitor are ideal for checking GPU temp.
- Idle Temperature: A GPU at desktop might be between 30°C and 60°C.
- Under Load: Most modern graphics cards are designed to operate safely up to 83°C-90°C under heavy load, but lower is always better for performance and longevity. Aim to keep it below 85°C during extended gaming sessions.
Hard Drive And Ssd Temperature
Storage drives can also overheat, though they are less of a concern than CPUs and GPUs. HWMonitor often shows drive temperatures. High temperatures can reduce an SSD’s lifespan and cause a hard drive to fail.
- A typical safe operating range for most drives is between 0°C and 60°C (32°F – 140°F).
- If your drives are consistently above 50°C (122°F), consider improving case airflow around them.
What Are Safe And Dangerous Temperatures
Knowing the numbers is one thing; understanding what they mean is another. Safe temperatures vary by component and manufacturer, but these general guidelines will help you assess your system’s health.
Safe Operating Ranges
- CPU: Idle: 30-50°C. Gaming/Load: 70-85°C. Max (TJunction): Usually 95-105°C (varies by model).
- GPU: Idle: 30-60°C. Gaming/Load: 70-85°C. Max: Often 90-100°C as a throttle point.
- Storage (HDD/SSD): Ideally 30-50°C. Above 60°C for extended periods is risky.
Signs Of Overheating
Your computer will often tell you it’s too hot through its behavior. Watch for these warning signs:
- Performance Throttling: Sudden, significant drops in frame rates or application speed.
- System Crashes or Blue Screens: Random shutdowns or Blue Screens of Death (BSOD) under load.
- Loud Fan Noise: Fans constantly running at maximum speed, sounding like a jet engine.
- Artifacting on Screen: Strange visual glitches or colored dots during gaming, often a sign of GPU overheating.
How To Lower High Pc Temperatures
If you discover your temperatures are too high, don’t panic. There are several practical steps you can take to improve cooling and bring those numbers down.
Improve Airflow Inside Your Case
Good airflow is the most important factor for cooling. Ensure your case fans are set up correctly.
- Front/Side Fans: These should typically be set as intake, bringing cool air into the case.
- Rear/Top Fans: These should be set as exhaust, pushing hot air out.
- Check for Dust: Regularly clean dust filters and use compressed air to remove dust from heatsinks and fans. Dust acts like a blanket, trapping heat.
Reapply Thermal Paste
Thermal paste is the material between your CPU and its cooler. It can dry out or become ineffective over time, typically after 3-5 years.
- Power down and unplug your PC.
- Carefully remove the CPU cooler.
- Clean off the old thermal paste from both the CPU and cooler with isopropyl alcohol and a lint-free cloth.
- Apply a small, pea-sized drop of new thermal paste to the center of the CPU.
- Reattach the cooler evenly to spread the paste.
Adjust Fan Curves
Your motherboard controls how fast your fans spin based on temperature. A more aggressive fan curve makes fans spin faster at lower temperatures, improving cooling at the cost of more noise.
- You can adjust fan curves in your BIOS/UEFI or using software like MSI Afterburner (for GPU) or fan control utilities from your motherboard manufacturer (for case/CPU fans).
Consider Hardware Upgrades
If other steps don’t work, a hardware upgrade might be necessary.
- CPU Cooler: Upgrade from a stock cooler to a larger air cooler or a liquid cooling system (AIO).
- Case Fans: Add more fans or replace existing ones with higher-quality, higher-airflow models.
- PC Case: If your current case has poor ventilation, moving your components to a case with better airflow design can make a dramatic difference.
