Struggling to decide if your PC is getting too hot? Or perhaps you don’t know what the ideal temperature for a processor is. Whatever the case – this blog post has been designed to answer every question you’ve ever had about CPU temperatures.  



We’ll be showcasing why CPU temperature is important, explain how to find out what your temp is, uncover the best temperature for your workload, and explore some top tips for helping your PC stay cool.  



Why is CPU Temperature Important?  

Excess heat can affect both the longevity of your processor and your system’s overall performance, resulting in instability such as unexpected freezes, crashes, and shutdowns. Prolonged high temperatures can shorten the lifespan of the CPU and may even affect your other components. 

Keeping your processor cool enables it to continue performing at optimum temperatures, enabling you to enjoy rapid processing, seamless multitasking, and much more.  


What is a Normal CPU Temperature? 

The temperature of your CPU depends on your workload and cooling solution. However, the general rule of thumb is that your processor should be anywhere between 60-80°C when it’s under load. A term you should familiarise yourself with is TJMax. It refers to the temperature a CPU can reach before it starts to throttle. Generally, anything higher than 90°C is considered too high and therefore potentially dangerous. However, there are some exceptions, as AMD AM5 CPUs are designed to safely operate at a 95°C TJMax.

Most processors will automatically begin to throttle if it reaches a high temperature which will help to bring down your CPU’s overall temp. If it’s still unable to cool down properly, your PC may suddenly blue screen or switch off altogether. 

How Can I See What My CPU Temperature Is? 

You can check your CPU temperature in two ways:  

  • Via the BIOS 
  • Via third-party software  

Via the BIOS 

  1. Restart your computer.  
  1. As your PC is booting up, press the hotkey assigned to your BIOS, such as F8 or Delete.  
  1. Once in BIOS, locate the ‘Fan Curve’ or ‘Overclocking’ section. 
  1. Here you’ll be able to see detailed real-time information about your CPU temp. 

Via Third-Party Software 

  1. Download your chosen monitoring software such as Core Temp, Ryzen Master, Open Hardware Monitor, or HWMonitor.  
  1. Once installed, launch your chosen software and locate your CPU from your hardware list. 
  1. Here you should see your CPU’s current temperature, which will be displayed in either Celsius or Fahrenheit.

What Temp Should My CPU Be?  

Don’t know what temperature your CPU should be? The table below details the average ideal and risky temperatures for your processor depending on load. 

IdleLow LoadMax Load
IdealLess than 50°CLess than 70°CLess than 80°C
RiskyAnything higher when ideal needs to be investigated Between 80-85°CBetween 85-90°C
Dangerous–Higher than 85°C is potentially dangerousHigher than 90°C could be dangerous

We’ve also broken it down further.  

When Idle 

When your CPU is idle, it’s experiencing minimum loads which is typically simple internet browsing or watching videos online. These tasks won’t put your CPU under any strain since they don’t require any complex processing. 

The perfect temperature for an idle CPU is less than 50°C. Anything higher than this is considered dangerous, and you need to do further testing to see what’s making your processor this hot.  

When Gaming 

Gaming will put your CPU under strain as this will require more complicated processing, and your CPU will need to be directly communicating with both your memory and graphics card for your PC to render any visuals.  

The optimum temperature for a CPU is less than 70°C. Anything between 80-85°C is risky, and you may want to invest in some extra cooling. Higher than 90°C is dangerous. 

When Streaming 

Live streaming seriously puts your processor under pressure. Now your CPU is having to process several multi-core applications at once, the game you’re trying to play, and the stream you are actively encoding.  

As a result, the ideal temperature for a CPU when live streaming is less than 80°C. Anything between 85-90°C is considered dangerous and higher than 90°C.

What Affects My CPU Temperature?  

Multiple factors can affect your CPU temperature. This includes: 

  • Your workload. If your CPU is experiencing heavy loads, it will add extra strain and therefore increase your temperatures. 
  • Airflow. Insufficient airflow can cause temperatures to increase as your CPU isn’t getting the cooling it needs. This could be that your thermal solution isn’t sufficient enough or your case lacks good quality airflow.  
  • Overclocking. By overclocking, you are increasing the clock rate and voltage of your processor, causing it to perform higher than intended by the manufacturer. This in turn results in increased temperatures.  
  • Your thermal paste. If you haven’t put enough thermal paste on your CPU, there won’t be sufficient heat transfer between the processor and cooler to keep temperatures to a minimum.  
  • Cleaning. If your PC isn’t regularly cleaned, a build-up of dust can soon start to infiltrate the inside of your chassis, blocking fans and even entering vital components. Both of which will harm your PC’s cooling capabilities.  

How Can I Bring My CPU Temperature Down?  

Thankfully, not all hope is lost! If your CPU temperature is too high, there are a few simple tricks you can do to hopefully get them back down again.  

Improve Your Airflow 

Increasing your airflow can help to reduce any excess temperatures as you’ll now have a consistent stream of air flowing throughout the interior of your case and fans, allowing them to dissipate heat faster and more efficiently.  

Adjust Fan Speeds  

You can also consider adjusting your fan speeds, especially if your processor struggles under heavy loads.  

To do this, go into the BIOS or dedicated fan control software and manually adjust the fan curves to allow them to ramp up when under pressure for better airflow. You can also configure the fans to stop spinning (or spin very slowly) when idle, meaning you can still enjoy a whisper-quiet operation. 

Add More Thermal Paste  

Adding more or even repasting your CPU can help to improve heat transfer between your processor and cooler, facilitating better dissipation for improved temperatures.  

How to Apply Thermal Paste

Don’t know how to apply thermal paste? Here’s what you need to know.  

Check Your CPU Cooler 

We recommend that you also check the base of your CPU cooler and ensure that the protective plastic has been removed. Mistakes can happen and if this plastic has been kept on it will block effective heat transfer between the processor and cooler, causing temperatures to increase. 

Upgrade Your Cooling 

If your budget allows for it, you can try upgrading your cooling configuration. Opting for an AiO over air cooling will notably help those who regularly use their PC for more demanding applications. Plus, you’ll want to ensure that you have more than enough fans. Simply installing just one or two isn’t going to deliver the airflow you need for sufficient cooling.

Make Time for Regular Cleaning  

Taking time to clean up any dust or excess grime around your components can help to improve your performance and cooling capabilities. There’ll be no more dust blocking fans, stopping them from circulating enough air throughout your case.
