Is Your PC Running Hot? How to Easily Check CPU Temperature
Is your computer acting up lately? Maybe it's suddenly shutting down, freezing, or feeling extra slow when you're gaming or working hard.
Especially when the weather gets hot, an overheating CPU could be the culprit. It's also super important to monitor your CPU's heat if you're pushing its limits with overclocking – you don't want to accidentally fry that awesome processor (like a prized Ryzen 7 7800X3D) by pushing it too hard!
Why Can't Windows Just Tell Me?
Strangely enough, Windows doesn't have a built-in, easy way to show you how hot your CPU is running. Sure, you could restart your PC and dig around in the system BIOS, but that's a clunky process just to see a simple temperature reading.
Luckily, there are plenty of free tools out there that make checking your CPU temperature a breeze. Once you know the temperature, you'll know if you need to take action to cool things down. We'll cover how to do that after recommending some software.
First Things First: Bust the Dust!
Before you even download any software, do a quick visual check. Are your computer case fans, vents, and heatsinks covered in dust? Dust buildup is a major cause of overheating because it blocks airflow. Grab a can of compressed air (every PC owner should have one!) and give your PC's insides a good cleaning. This alone can make a huge difference.
Easy Way: Check CPU Temp with Core Temp
The quickest and most straightforward tool for checking your CPU temperature is called Core Temp.
Installation Tip: Be careful when installing! Like many free programs, Core Temp might try to bundle extra software you don't need. Pay close attention during setup and uncheck any boxes for optional installs.
Once it's installed and running, Core Temp gives you a clean, simple view of your CPU's current status, including the average temperature reading at the bottom.
Want more detail? Look for the "Show hidden icons" arrow in your Windows system tray (usually bottom-right). Core Temp often puts individual temperature readings for each core of your processor there. You can customize what shows up in the system tray via Core Temp's settings, but the defaults are usually perfect for quickly seeing if things are normal or getting too hot.
Other Great Tools for Monitoring Temps
Core Temp is great for simplicity, but you have other excellent options:
HWInfo: This is a super detailed system monitoring powerhouse. It gives you TONS of information about every part of your PC. If you run it in "sensors-only" mode and scroll down to the CPU section, you'll find current temperatures along with many other technical details.
NZXT CAM: Known for its slick, easy-to-read interface, CAM shows helpful info about your CPU, graphics card, RAM, and storage all in one place. It also offers extras like an in-game FPS counter and overclocking tools. Plus, you can even monitor your PC remotely using their mobile apps.
Open Hardware Monitor & SpeedFan: These are two other popular and reliable monitoring tools that track various system stats, including CPU temps.
So, you've got choices! But if all you want is a quick CPU temperature check, Core Temp is hard to beat for its simplicity.
A Quick Note for AMD Ryzen Owners
If you have an AMD Ryzen processor, you might notice some monitoring tools (like HWInfo) showing two different CPU temperatures.
Look for "Tdie": This reading generally represents the actual temperature measured directly on the processor die. This is the one you usually want to pay attention to.
"Tctl": This is the "control temperature" reported to the cooling system. Sometimes, it includes an offset (an added value) to ensure consistent fan behavior across different Ryzen chip models.
Most simpler programs (like Core Temp) that only show one temperature usually already account for any offset, so you don't need to worry about it there.
Checking Temps in Windows 10?
Since Windows 10 (like Windows 11) doesn't have its own temperature gauge, the process is exactly the same: you'll need to use one of the handy third-party tools mentioned above, like Core Temp.
What's a 'Good' CPU Temperature?
Every processor model has a maximum safe operating temperature, often listed as "Tj. Max" (Temperature Junction) in monitoring software. You can also look up your specific CPU model on CPU World's website to find this limit if the software doesn't show it.
Important: That Tj. Max is the absolute limit before the CPU shuts down to prevent damage. You never want your CPU running near that temperature regularly, as it can shorten its lifespan.
Here’s a general guideline for CPU temps while it's working hard (under load):
Under 60° C: Everything is running cool and happy!
60° C to 70° C: Still perfectly fine. Maybe consider cleaning dust if temps creep up over time.
70° C to 80° C: Getting warmer. If you're not overclocking, double-check for dust buildup or failing fans. If you are overclocking, you might be pushing things.
80° C to 90° C: Too hot for comfort during long sessions. Check fans and dust immediately. If overclocking, reduce your settings (especially voltage!). Exception: Some powerful laptop CPUs might hit the low 80s during intense gaming while plugged in; this can be normal, but if it goes over 85°C, investigate.
Over 90° C: Danger zone! Your CPU is likely overheating significantly. Stop demanding tasks immediately and figure out the cooling issue.
CPU Running Too Hot? How to Cool It Down
If your temperatures are consistently high, here's what you can do:
Clean Your PC (Again!): Seriously, dust is the enemy. Make sure all fans are spinning, air vents are clear, and heatsinks are free of blankets of dust. Ensure fans are blowing air in the correct directions (usually intake in front/bottom, exhaust out back/top).
Check/Replace Thermal Paste: The paste between your CPU and its cooler transfers heat. Over several years, this paste can dry out and become less effective, causing temps to spike. Cleaning off the old paste (use isopropyl alcohol) and applying a fresh layer (brands like Arctic or Noctua sell it cheap online) can drastically lower temps.
Consider a Better CPU Cooler: If cleaning and new paste don't help, your current cooler might just not be up to the task, especially if it's the basic one that came with the CPU or if you're overclocking.
- Air Coolers: Even an affordable tower cooler like the Cooler Master Hyper H412 (around $23) is a big step up from stock coolers. High-end air coolers like the Noctua NH-D15 (around $110) offer amazing performance but are very large and need space.
Liquid Coolers (CLCs/AIOs): Closed-loop liquid coolers often provide excellent cooling with easier installation than massive air coolers. For moderate needs, a 120mm unit might suffice. For serious overclocking or high-end CPUs, look at models with larger 240mm or even 360mm radiators.
Final Thoughts
Keeping an eye on your CPU temperature is easy with the right tools and crucial for a healthy, long-lasting PC. Don't ignore warning signs like sluggishness or shutdowns!
Helpful Tip: Regularly cleaning the dust out of your PC is the simplest and often most effective way to keep those CPU temperatures down. Make it a habit!
