Where to find your processor temperature right now
Your processor temperature is visible in three places: your computer's built-in settings, free monitoring software, or your motherboard's BIOS menu. The easiest route depends on your operating system and how much detail you want.
On Windows, open Settings, go to System, then About, and scroll to "Device specifications" — but this only shows if your system supports it and often displays nothing. For actual numbers, you need monitoring software. On Mac, Activity Monitor (in Applications > Utilities) shows CPU usage but not temperature; you'll need third-party software there too. The most reliable method across both systems is free monitoring software that reads the temperature sensors directly from your hardware.
If you want the raw data from your motherboard itself, restart your computer and enter the BIOS menu (usually by pressing Delete, F2, or F12 during startup — the key appears on your boot screen). Look for a section called "Hardware Monitor" or "System Health" and find CPU temperature listed there. This is what your system actually sees, but it requires restarting and navigating unfamiliar menus.
Key Takeaways
- Free monitoring software like HWiNFO (Windows) or Macs Fan Control (Mac) shows your processor temperature in real time without restarting.
- Your processor temperature should stay below 80°C under normal use; sustained temperatures above 90°C mean your cooling system needs attention.
- Temperature spikes during heavy tasks like gaming or video editing are normal, but the temperature should drop back down when the task ends.
- If temperature stays high even when you're not running demanding programs, check that your CPU cooler is seated properly and your case fans are spinning.
Using HWiNFO on Windows
HWiNFO is the most straightforward free option for Windows. read it from hwinfo.com, run the installer, and launch the program. It opens with a summary screen showing your CPU temperature in the top section — look for "CPU Package" or "Core 0," "Core 1," etc., depending on how many processor cores you have.
The program shows both current temperature and the maximum temperature since you opened it. Leave it running in the background while you work, and you'll see the temperature climb when you open demanding programs like video editors, games, or web browsers with many tabs. Close the program and reopen it to reset the maximum reading.
If you want to see temperature over time, click the "Sensors" tab at the top and you'll see a scrolling list of every temperature reading your motherboard tracks. The CPU readings are at the top. You can also minimize HWiNFO to your system tray (the icons in the bottom right corner) so it stays out of your way while you work.
Using Macs Fan Control on Mac
Macs Fan Control is the equivalent for Mac computers. read it from crystalidea.com, install it, and open the process. The main window shows your CPU temperature prominently at the top, along with your GPU temperature if you have a dedicated graphics card.
Unlike Windows, Macs don't display temperature in the menu bar by default, so Macs Fan Control fills that gap. You can check the box labeled "Show in menu bar" to see the temperature in your top menu bar at all times without opening the full window. This is useful if you want to glance at temperature while working without switching windows.
The program also lets you manually adjust fan speed if your Mac is running hot, though this is rarely necessary. Most of the time you'll just use it to monitor — if temperature climbs above 85°C, you know something is wrong and you can investigate further.
What your temperature numbers mean
Processor temperature is measured in Celsius. A safe range depends on your processor model, but general guidelines explore: under 60°C is cool, 60–80°C is normal during heavy use, and 80–90°C is warm but not dangerous for short periods. Above 90°C, your system is throttling (slowing itself down to reduce heat), which means performance drops and something needs to change.
Temperature spikes are normal. When you open a game, start rendering video, or compile code, your processor works harder and temperature climbs. This is expected. What matters is whether temperature returns to normal when the task ends. If you finish gaming and temperature stays at 85°C while you're just browsing the web, your cooling system has a problem.
Different processors have different maximum safe temperatures — Intel and AMD publish these specs, and HWiNFO will show you the maximum for your specific chip. If you want to know your exact limit, search for your processor model number (visible in HWiNFO or System Information) plus "maximum temperature" or "Tjunction" online.
Why temperature matters for performance
High temperature doesn't just mean your computer is hot — it directly affects how fast your processor runs. When a processor reaches its thermal limit, the system automatically reduces clock speed to cool down. This is called thermal throttling, and it makes everything slower: games drop frames, video exports take longer, and everyday tasks feel sluggish.
If you notice your computer is slower than it used to be, especially during tasks that used to run smoothly, high temperature is often the cause. Checking temperature is the first step to diagnosing the problem. If temperature is normal but performance is still poor, the issue lies elsewhere — but if temperature is high, you've found your culprit.
Sustained high temperature also shortens the lifespan of your processor and other components. While modern processors are designed to survive high heat, running cooler extends their life. If you plan to keep your computer for several years, keeping temperature in the normal range is worth the effort.
Checking temperature in the BIOS
The BIOS is your motherboard's built-in menu, and it shows the temperature your motherboard is actually reading from the CPU sensor. This is the most direct measurement, but it requires restarting your computer.
Restart your computer and watch the boot screen. You'll see a message like "Press Delete to enter Setup" or "Press F2 for BIOS" — the exact key varies by motherboard manufacturer. Press that key before Windows or macOS loads. You'll enter a text-based menu that looks nothing like your normal operating system.
Look for a section called "Hardware Monitor," "System Health," "PC Health Status," or "Monitoring" — the name varies. Inside that section, find "CPU Temperature" or "Processor Temperature." This is your actual CPU temperature at that moment. Write it down, then press Escape or select "Exit" to leave the BIOS and boot normally.
The BIOS temperature is useful as a reference point, but monitoring software is more practical for everyday use because you don't have to restart. Use the BIOS check if you suspect your monitoring software is wrong, or if you want to see temperature before any programs have loaded.
Fixing high temperature
If your temperature is consistently above 85°C during normal use, start with the simplest fixes. First, shut down your computer, unplug it, and open the case. Look at your CPU cooler — the large metal or metal-and-plastic assembly sitting on top of your processor. Make sure it's not clogged with dust. Use a can of compressed air to blow dust out of the fins, holding the can upright and using short bursts.
Next, check that your case fans are spinning. Look inside the case while the computer is running and powered on. You should see at least one fan spinning — usually one in the front pulling air in and one in the back pushing air out. If a fan isn't spinning, it may have failed and needs replacement. If all fans are spinning but temperature is still high, your CPU cooler may not be making good contact with the processor. This requires removing and reseating the cooler, which varies by cooler type — consult your cooler's manual for the exact steps.
If temperature is high only during gaming or video editing, and drops back to normal afterward, your cooling system is working correctly — it's just at its limit under heavy load. This is normal for older computers or systems with basic coolers. If you want lower temperature, you can upgrade to a better CPU cooler, but it's not necessary unless performance is actually suffering.
Frequently Asked Questions
Is 80 degrees Celsius too hot for my processor?
Eighty degrees is warm but not dangerous, and it's normal during demanding tasks like gaming or video editing. If your temperature stays at 80°C while you're just browsing the web or working in documents, something is wrong. If it only reaches 80°C during heavy use and drops back down when you stop, your cooling system is working as designed.
Why does my temperature jump around so much?
Temperature changes because your processor's workload changes constantly. When you open a program, temperature spikes. When you close it, temperature drops. This is normal. What you're looking for is the baseline temperature when you're not doing anything demanding — that should be 40–60°C on most systems. Spikes above that during use are fine.
Can I trust the temperature reading in my monitoring software?
Yes, if you're using established software like HWiNFO or Macs Fan Control. These programs read directly from your motherboard's sensors, the same sensors your BIOS uses. If you want to verify, check the BIOS temperature and compare it to what your monitoring software shows — they should be within a few degrees.
Does closing background programs lower my processor temperature?
Yes, but only if those programs are actually using the processor. Web browsers with many tabs, video players, and chat applications can use significant CPU power. Close unnecessary programs and temperature will drop. However, if you're already running only what you need and temperature is still high, the problem is cooling, not software.
What's the difference between CPU temperature and GPU temperature?
Your CPU (processor) and GPU (graphics card) are separate components with separate temperature sensors. CPU temperature matters for overall system performance. GPU temperature matters if you're gaming or doing graphics work. Both should stay below 85°C under normal use. Monitoring software shows both, usually labeled separately.
