Is your computer’s CPU too hot? If your PC starts spontaneously shutting down, locking up, or acting sluggish during intense tasks, overheating could be the issue. Keeping tabs on your CPU temperatures is crucial when you’re overclocking your PC’s processor, too—you don’t want to accidentally push the performance pedal too far to the metal when you’re supercharging your pricey Core iK or AMD Ryzen X, especially given how hard it is to acquire processors these days.

Bizarrely, Windows doesn’t offer any way to check your computer’s CPU temperature. You could dive into your system’s BIOS to find the information, but that’s a lot of hassle to find a simple sensor reading. Fortunately, several free programs exist that make it easy to see your processor’s temperature.

How to check your CPU temperature

The fastest, easiest way to check your CPU temp is using the aptly named Core Temp. Be mindful during installation though! Like many free programs, it tries to install bloatware unless you uncheck some boxes during setup.

Once installed, open Core Temp to see a no-frills look at the current state of your CPU, including an average temperature reading at the bottom of the window. If you want even more detail, click the Show hidden icons button in the system tray located at the right edge of your Windows taskbar. You’ll see a temperature listing for every individual CPU core in your computer.

core temp

Core Temp’s Settings menu allows you to tweak exactly what you’ll see in the system tray, and how you’ll see it, but the default configuration makes it dead-simple to see if your CPU is overheating or performing as expected.

Core Temp isn’t the only option though. HWInfo is an in-depth system monitoring tool that provides deep details about every piece of your PC’s hardware. If you choose to run it in sensors-only mode, scrolling down to the CPU section—the dedicated section, not the CPU temperature portion of the motherboard listing—reveals current temps and other nitty-gritty details.

nzxt cam

NZXT’s Cam software is another popular option with a diverse skillset. Its slick interface is easier to read at a glance than those on most other monitoring tools, and the program shows all sorts of useful info about your CPU, graphics card, memory, and storage. Cam also includes an in-game FPS overlay and overclocking tools, among other features. You can use NZXT’s Cam mobile apps to keep tabs on your software when you’re away from your PC, too.

Open Hardware Monitor and SpeedFan are other well-regarded monitoring tools that can track system information. You’ve got options! But for simply checking your computer’s CPU temperatures, Core Temp’s straightforward focus can’t be beat.

ryzen tdie vs tctl

Finally, note that if you’re running an AMD Ryzen system, including 3rd-gen models like the ferocious Ryzen 9 X or the more modest Ryzen 5 X that’s the best gaming processor for most people, you may see two different CPU temperature readings. You want the “Tdie” reading, depending on how the program you’re using displays the info. It’s a measurement of the actual heat on the die.

The alternative “Tctl” reading is the control temperature reported to your cooling system and sometimes includes a temperature offset to ensure universal fan speed behavior between the various Ryzen chips. Any of the programs above that list a single temperature account for the offset already.

What’s the best temp for your CPU?

The maximum supported temperature varies from processor to processor. Most of the free monitoring software mentioned above lists the information as “Tj. Max.” That stands for the temperature junction, or the highest operating temperature of the hardware. If you don’t see the information for some reason, search the CPU World website for your CPU’s model number to find the information. Every program listed above displays your processor’s model number, so it’s easy to find.

But that’s the maximum temperature—the point at which your processor freaks out and shuts down to avoid damage. Running anywhere near that hot regularly is bad for the long-term life of your hardware. Instead, follow this general rule of thumb regarding CPU temperatures under load.  

  • Under 60° C: You’re running great!
  • 60° C to 70° C: Still running fine, but getting a bit warmer. Consider cleaning the dust out of your PC if CPU temperatures continue to creep up over time.
  • 70° C to 80° C: This is hotter than you want to run unless you’re pushing an overclock. If you’re not, definitely check to make sure your fans are working and there aren’t dust bunnies clogging up your system’s airflow.
  • 80° C to 90° C: Now we’re getting too hot for long-term comfort. Check your hardware for broken fans or dust build-up, and if you’re overclocking, dial back your settings—especially the voltage if you’ve tweaked it. One notable exception: We sometimes see more powerful laptop processors hit the low 80s during gaming sessions when plugged in, at which point they start throttling back performance. This is expected, but if temperatures cross 85° C, be concerned.
  • Over 90° C: Danger, Will Robinson!

How to lower your CPU temperatures

If you’re regularly encountering high CPU temperatures, there are some steps you can take to try and fix the issue.

clean pc

First, clean out your PC. High CPU temperatures are often caused by years of dust and grime built up inside a PC, clogging fans and crucial air pathways. Local hardware stores usually charge outrageous prices for canned air, but you can pick up a bottle for about $8 on Amazon. PCWorld’s guide on how to clean your PC can walk you through the process. While you’re at it, check to make sure that all your fans are working correctly, pointed the right way, and that none of the vents in your PC are blocked. (Also, make sure your PC’s fans are set up for maximum cooling performance.) 

Hopefully that fixes the issue. If not, more intensive steps are in order. The thermal paste that transfers heat from your CPU to its cooler might have dried out if you’ve had your PC for a few years. That can cause temperature spikes.

Removing the old thermal paste with rubbing alcohol and applying a fresh layer can potentially help lower temperatures by a large amount. You can find small syringes of thermal paste by respected brands like Arctic and Noctua for under $10 on Amazon. (I’ve been a happy Arctic Silver 5 user for years now.)

install cpu paste

If all that doesn’t help, your cooling solution simply might not be capable of keeping up with your CPU’s heat output, especially if you’re pairing a stock cooler or a modest third-party cooler with higher-end chips—and doubly so if you’re overclocking. Buying a new CPU cooler may be in order.

The Cooler Master Hyper ($35 on Amazon) is a solid, affordable air cooler. With its larger heatsink and fan, it’s a solid step up over stock AMD and Intel CPU coolers. Moving up in size and price, the Noctua NH-D15 ($ on Amazon) is one of the most effective air coolers ever to hit the streets, but its large size might block memory access or not even fit in smaller cases.

Closed-loop liquid cooling solutions (CLCs) provide far cooler temperatures than air coolers with minimal hassle and easy installation. EVGA’s mm unit ($60 on Amazon) is a great entry-level CLC, but if you plan on overclocking, consider moving up to a model with larger mm radiator, like the straightforward-named EVGA CLC ($90 on Amazon). Several brands are available, but we’ve been using EVGA’s closed-loop coolers in PCWorld’s powerful, dedicated graphics card testing system to great results.

We’re also partial to the even larger mm NZXT Kraken X63 ($ on Amazon). All that extra metal and fans can accommodate the fiercest overclocks.

How to Monitor CPU and GPU Temperatures on Windows 10

How to Monitor Your CPU Temperature

Checking your system's CPU temperature is similar to checking your car's oil: You don't need to do it daily, but it's something to keep an eye on every few months, especially if you regularly strain your system with higher loads like you'll do with the Best CPUs for Gaming. 

Luckily, checking your CPU temperature is pretty easy and doesn't require you to open up your PC and stick a thermometer inside. Instead, every CPU comes with digital thermal sensors built-in, so all you need is a bit of software to read their measurements.

Below we'll break down what a healthy range of temperatures is for a CPU, how to check your CPU temperature and what to do if your CPU's temperatures are too high.

What's a Good CPU Temperature?

When the CPU is idle, or not being used by any program, a healthy temperature is anything under or around 50 degrees Celsius ( degrees Fahrenheit). Under higher load, such as when playing a game, rendering a video, or other intensive tasks, your CPU consumes more power and, thus, runs at a higher temperature.  This is more important than idle temperatures (assuming idle temps are fine) and you'll want to periodically monitor your CPU temperature under load to ensure it's adequately cooled during such conditions. 

Under load, you want your CPU to ideally stay under 80 degrees Celsius ( degrees Fahrenheit), though some CPUs may run hotter when they're in ultrabooks, gaming laptops, or small-form-factor (SFF) computers. You have some wiggle room to creep past 80 degrees Celsius, but anything above 95 degrees Celsius ( degrees Fahrenheit) is critical. At this point, some CPUs will begin throttling, meaning the clock speed will slow down to ensure it doesn't overheat, and your PC may turn off.

More advanced users who want the utmost confidence that their CPU can handle aggressive workloads should stress test their CPU to % using a program like Prime95 or AIDA64 . When running such a stress test, keep a close eye on the temperatures, using the tools mentioned below, and back off once they reach too high a number, i.e. anything above 95 degrees Celsius. We consider an ideal stress test to be one hour long, though your maximum temperature will likely level off after minutes. 

How to Monitor Your CPU's Temperature

Checking your CPU temperature is as easy as firing up a monitoring program and using it to read out the value. Examples of these programs are HWMonitor, Core Temp, or NZXT's CAM. These three are just a few examples of many, and for the purpose of this how-to we'll show you how NZXT's CAM and Core Temp work because we have found that these two are the easiest to use for casual purposes.

CAM is developed by PC case, power supply and CPU cooler manufacturer NZXT. While it's intended to be used with their product, it works really well as a casual monitoring tool even if you don't own any NZXT hardware. 

Once installed, CAM offers a well-presented user interface (UI). The first block features the CPU's status, which shows the load, temperature, clock speed and cooler fan speed. You can click on this block to access further details, as shown in the image below.

As you can see, the current temperature of this system's CPU is 41 degrees Celsius, which is a healthy idle temperature. 

CAM also has an overlay, which automatically turns on when you enter a game when CAM is running. This overlay can show you your CPU's status while in-game, providing you with load temperature measurements.

You can also use the Core Temp tool to monitor the temperatures, which is a simpler tool that works with a more basic UI. Just be sure to untick the freeware in the installation menu first. 

As you can see, this CPU has been running at a temperature of 46 degrees Celsius and a maximum of 75 degrees Celsius ( degrees Fahrenheit) and is, therefore, running at a normal temperature. The stress test temperature was achieved by running Prime95 for about 30 minutes, though the CPU hit its maximum temperature of 75 degrees Celsius within 10 minutes.

With Core Temp, the best way to monitor your temperature while gaming is to just have a good session, and then check back in with the program to see what the maximum recorded temperature is. Again, if this figure is at or beyond 95 degrees, you should be concerned. Anything between 80 and 95 degrees may have room for improvement.

What Should I Do if my CPU Temperature Is too High?

If under load your CPU temperature is exceeding 80 degrees Celsius, you should check your system to ensure the CPU's cooling is adequate. 

Here's a checklist of things to look for:

  • Is your PC clean and free of dust (including radiator)?
  • Are all your PC's fan's spinning under load?
  • How old is your PC?
  • When was the last time you applied fresh thermal paste between your CPU and CPU cooler? If it's been over three years, consider re-applying the thermal paste.
  • Does your model CPU cooler specify a higher cooling capacity than your CPU's rated TDP?
  • Are you using a SFF PC, too small of a CPU cooler or a laptop? 

For SFF PCs and laptops, it's possible that there's minimal cooling, as the device was never intended to be used under high loads for extended periods of time. For example, most laptops come with very compact cooling solutions that work well for short term performance bursts but need to slow down during extended gaming sessions to stay below the shut-off threshold. Gaming laptops are often bulky because they're packed with extensive cooling systems. 

If you are using a full-size gaming PC, however, and think your cooling should be adequate, you may want to re-apply thermal paste to your CPU. Most thermal paste's performance seriously degrades after about three years. Applying fresh paste and cleaning the system from dust can offer much better cooling power and significantly better performance. This applies both to pre-built and custom-built PCs.

How to Reduce CPU Temperature

There are many ways to fix overheating problems. You can use simple techniques such as dusting the CPU fan, using a more powerful air cooler fan on your CPU or applying new thermal paste.

Since liquid cooling is more effective at transferring heat compared to air, liquid cooling can reduce the CPU temperature by °F (°C).

Although not every CPU requires liquid cooling, air cooling can overheat the CPU if it doesn’t match the CPU’s requirements.

For instance, if you are using a W air cooler in a CPU that requires W, then the CPU will overheat and throttle. Besides liquid cooling, you can use any of the following simpler techniques to lower and maintain normal temperature for CPUs:

  • Don&#;t do overclocking if not necessary.
  • Improve airflow inside the case.
  • Put your computer in a cold environment.
  • Clean your computer regularly to get rid of dirt and dust.
  • If you have a defective fan or heatsink, replace it.
  • Apply thermal paste on CPU and heat sinks.
  • Close unused background programs.
  • Buy cooling pads for your laptop.

Closing Words  

You cannot go wrong with any of these options. All of these programs are free (or offer free-trial) and easy to use on any Windows PC. Install one of these CPU monitors today to keep an eye on your CPU processor because it&#;s one component that its health is vital for your computer system.
