ARCTIC MX-7 (8 g) - Ultimate Performance Thermal Paste, Long Durability
Quick answer: Our top pick in 2026 is the Noctua NH-U12S Redux — our #1 rated choice. See the full ranked comparison, alternatives and buying advice below.
How Do I See CPU Temp on My PC?
The fastest way to see CPU temp is to install a free monitoring app such as HWiNFO, Core Temp, or MSI Afterburner, launch it, and read the temperature displayed for each core in real time. Alternatively, you can check your motherboard’s BIOS or UEFI at startup, which shows the current CPU temperature on the hardware monitor page. Windows itself does not include a built-in CPU thermometer, so a dedicated utility is the most convenient and accurate option. Once installed, these tools update continuously, letting you watch temperatures at idle, during gaming, or under heavy workloads.
Best Free Software to See CPU Temp
Several reliable, free programs make it easy to see CPU temp. HWiNFO offers the most detailed sensor data, Core Temp is lightweight and beginner-friendly, and MSI Afterburner adds an in-game overlay. Your motherboard software may also include a monitoring dashboard. Pairing good monitoring with proper cooling hardware gives you the full picture of your system’s thermal health.

How to See CPU Temp in the BIOS
Every motherboard displays CPU temperature in its BIOS or UEFI. Restart your PC and press the setup key (often Delete or F2) during boot, then look for a hardware monitor or system status page. This method is useful for a quick baseline reading, though it only shows idle temperatures since the system is not under load. To see CPU temp during gaming or rendering, a software overlay is far more practical and reflects real usage alongside your airflow setup.
Setting Up an In-Game Temperature Overlay
MSI Afterburner paired with RivaTuner Statistics Server lets you display CPU temperature directly on screen while gaming. This is the best way to see CPU temp under real load and catch throttling as it happens. Configure the overlay to show core temperature, clock speed, and usage, then play as normal. If temperatures climb toward the thermal limit, you will know instantly and can plan a cooler upgrade before performance suffers.
What Temperatures Should You Look For?
When you see CPU temp readings, aim for 30-45°C at idle and 60-80°C under load. Brief spikes into the low 80s during heavy tasks are normal. Sustained temperatures above 90°C indicate a cooling problem worth addressing. Understanding these ranges helps you interpret the numbers your software reports and decide whether your build needs better airflow, fresh thermal paste, or a stronger cooler.
Troubleshooting High Temperatures Once You Can See Them
If your monitoring reveals high temperatures, start with simple fixes: clean dust from fans and heatsinks, confirm your cooler is mounted securely, and ensure your case has balanced intake and exhaust airflow. Reapplying quality thermal paste often lowers temperatures noticeably on older systems. For persistent heat, upgrading your cooler or improving case ventilation delivers lasting results and complements the right processor choice.
Frequently Asked Questions
What is the easiest way to see CPU temp?
The easiest way is to install a free app like Core Temp or HWiNFO, open it, and read the temperature shown for each core. These tools update in real time and require no special hardware. They work at idle and under load, giving you an accurate, continuous view of your processor’s temperature.
Can I see CPU temp without installing software?
Yes, you can check CPU temperature in your motherboard’s BIOS or UEFI by restarting and pressing the setup key during boot. This shows idle temperatures on the hardware monitor page. However, it cannot display temperatures during gaming, so software remains the best option for monitoring under real workloads.
Does Windows have a built-in tool to see CPU temp?
Windows does not include a native CPU temperature monitor in its standard interface. Task Manager shows CPU usage but not temperature. To see CPU temp, you need a free third-party utility such as HWiNFO, Core Temp, or your motherboard manufacturer’s monitoring software, all of which are safe and easy to use.
How often should I check my CPU temperature?
Check temperatures after building a new PC, after installing a new cooler, or if you notice performance drops or unusual fan noise. Otherwise, a periodic check every few months is enough for a healthy system. Regular monitoring during demanding tasks helps you catch cooling issues before they cause throttling or shutdowns.
