CPU Temperature Overheat: How Hot Should Be Your PC?

CPU Temperature Overheat

“Is my CPU overheating?” When a PC spontaneously shuts down, locks up, or starts chugging in a demanding game, this is one of the first questions we ask ourselves. Figuring that out is easy: all you need to do is install some monitoring software, like HWMonitor, and run it while you play a game. (If you want even more data than HWMonitor will give you, check out HWiNFO 64.) Keep an eye on those CPU Temperature Overheat to see if your CPU is the culprit.

When running at stock speeds, especially for desktops, CPU heat shouldn’t ever be an issue—assuming everything is working properly. And if things aren’t going well and your CPU does get too warm, thermal protection will kick in to keep any serious damage from being done. Laptops are slightly more complicated, as cooling a CPU and GPU in a slim chassis is simply more difficult than in a desktop. Again, the system should jump in and stop you before any damage is done, but you’re much more likely to experience a drop-off in performance if things start getting too toasty.

If you’re running stock and your CPU Temperature Overheat are hitting 80°C or higher, that’s a warning sign something isn’t working properly. Maybe a fan is dead, or thermal paste wasn’t applying properly, or your heatsink is super dusty. Most desktop CPUs should land in the 50-70°C range under load, so if you’re consistently pushing numbers into the 80s without overclocking, that definitely causes for concern.

Overclocking, on the other hand, paints a different picture. Killing a CPU via overclocking without touching the voltage is highly unlikely, but some auto-overclocking features in motherboard BIOSes will apply more voltage. When you push a CPU to higher clock speeds, most of the time you’ll just get a crash if things get too hot. But if you push voltages too high and mix in overclocking, then yes, you can kill a CPU.

Overclocking temperatures could in theory go as high as 90°C while still being ‘safe’, and the max temperature for many CPUs is listed in the 105-110°C range. But for long-term use, you’re much better off keeping things below 80°C in general and only pushing up to 85°C at the most. Besides, squeezing a final 100-200MHz out of a CPU usually requires more voltage (remember: recipe for a toasted CPU) and only gets you maybe 1-3 percent more performance anyway. And that’s assuming you’re not hitting a graphics bottleneck, in which case the CPU overclock might not even matter.

Luckily, there are plenty of options available to help combat the heat. The stock heatsink/fan that came with your CPU is fine for normal use, though not always as quiet as some people might like. In that case it’s also probably best to keep overclocking on the mild side of the equation.

What Happens When The CPU Temperature Overheat Is Too High?

In most cases, and with how computers are design today, the entire system shuts down when a CPU reaches a specific temperature to keep it from going up in smokes. This assures that your computer is kept from possible and further damage.

Regardless, regular high-temperature readings when using your computer for long periods of time could risk and damage the CPU. This also risks damaging the motherboard down the line. This is a reason why you need to make sure your CPU temperatures are kept at low levels.

How Hot Should My CPU Be When Playing Games?

There really is no definitive answer to such a question because of how diverse games are design. Some games may be CPU dependent while others are RAM or GPU dependent. Not to mention that the “safe” temperature readings vary from one CPU model to another.

No matter the case, a CPU temperature should play around 75-80 degrees celsius when gaming. When the computer is doing small processes or in an idle state, it should be around 45 degrees celsius to a little over 60 degrees celsius at most.

Ways To Reduce And Maintain Your CPU Temperatures At Low Levels When CPU Temperature Overheat

1. Allow Better Airflow

One of the easiest ways to reduce your CPU temperature is to allow better airflow inside the computer system. Unfortunately, many people fail to get this right.

There is a thing that we call positive airflow(more air goes in the system unit and less out), negative airflow(more air goes out than it goes in), as well as neutral or balanced airflow. It is best to go with a neutral airflow setup as opposed to going either positive or negative airflow.

Unless you have full control of each and every single fan’s RPMs, having more intake fans than exhaust fans, or the other way around, can be adjusted and manipulated in a way to still get the best airflow.

2. Cable Management

People usually ignore the importance of keeping tidy cable management. The fact that they take up a large amount of space is what makes a poor airflow. Taking some time to tidy your cables inside the computer is an effective way to promote better airflow.

3. Location Of Your System Unit

Among the common reasons why gamers have a higher CPU temperature reading has something to do with where their computer system is located. Chances of seeing higher temperatures is likely to happen if it is placed in a poorly ventilated area.

Even with the tidied up cable management and proper airflow setup, temperatures still show higher readings even in idle state. Make sure you move your computer to a well-ventilated area before it starts to develop problems.

4. Clean Your Computer Fans And Parts

Fans are what keeps the air to continuously flow in and out of your computer system. At the same time, they accumulate dust on the blades in the long run, a reason why it is vital to have them cleaned regularly.

5. Close The Case At All Times

It has been debated through the years that an open computer system is far better than keeping it closed. It may seem logical since an open case allows more air but it also attracts more dusts.

With a closed computer case, you guarantee you improve airflow and keep dusts at bay at the same time. This also promotes and ensures you are less likely to clean them more often.

6. Apply Thermal Paste

Reapplying the thermal paste usually does the trick. There are cases where a thermal paste is left out and dried out. This poses a threat to your CPU. Going for a better quality thermal paste leads to better results in transferring heat between the heat sink and the CPU.

When applying a thermal paste to your CPU, make sure you refer to our How to Correctly Apply Thermal Paste to CPU guide to get it done right and see ideal temperature readings after.
