How to reduce CPU temperatures

Have you experienced playing games and the computer just suddenly turns off on its own? There may be a number of reasons behind this problem but it is very common for a computer to shut down when the CPU temperature is too hot.

How do I lower my CPU temperatures?

This question has been asked many times after experiencing the problem when gaming. The risks are just too high to leave it as it is, and might lead to replacing your CPU, or worse, replacing your motherboard.

To keep yourself from facing such a dilemma, we have compiled a list of ways to effectively reduce your CPU temperatures. More on this below.

What Happens When The CPU Temperature Is Too High?

In most cases, and with how computers are designed 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?

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

There really is no definitive answer to such a question because of how diverse games are designed. 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

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.

Cable Management

People usually ignore the importance of keeping a 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.

Method 2- Cable management

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.

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.

A simple task like this usually is what solves a number of temperature drop problems. Do this on a regular basis to ensure you keep the temperatures maintained.

To do so, you need the right tools and equipment to make sure you are doing it right.

Things you need:

  1. A can of compressed air
  2. Dust mask

1

Remove the screws from the back of the covers

4.1 Remove the screws

2

Carefully remove the cover of the computer case

4.2 remove the cover of the computer case

3

Make sure you wear your protective gear

4.3 wear your protective gear

4

Use the can of compressed air to blow the dusts off

4.4 Use the can of compressed air

5

Blow the dusts off from the fans

NOTE: Make sure you hold the fans and never allow them to spin as you hit them with the compressed air. This leads to damages in the header of the fans.

6

Use the compressed air to dust off the power supply fans

4.6 Use the compressed air

7

Clear off the dusts around the casing using the compressed air, especially in areas where fans are installed

8

Refit and screw the covers back

4.8 Refit and screw the covers back

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 dust.

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

5. Close the case at all times

6

Apply Thermal Paste

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.

7

Invest In A Better CPU Cooler

Stock fans or coolers may be fine but they are not as efficient as an aftermarket CPU cooler or fan. Getting an aftermarket CPU cooler should be preferred and considered, especially if you are overclocking your CPU.

This should also reflect a huge difference in CPU temperatures. Refer and check out our Best CPU Cooler for Gaming review to make the right investment.

7. Invest in a better CPU cooler

8

Invest In A Case Fan

If your computer has 2 case fans installed, then you will surely see an improvement in temperature readings if you invest and get another case fan or two. These additions ensure your computer has better and more efficient airflow.

9

Get A Better PSU

It also is ideal if you get a better power supply. A modular PSU allows you to have full control of the wires, keeping the wires from messing with the airflow inside the system unit.

Know the difference between full vs semi vs non-modular power supply before you get a PSU and check our reviews on the best power supply for gaming to make the right selection according to your needs.

FAQs

How do I change my CPU temp limit?

When it comes to the temperature limit of your CPU, it is important that you should not change this. There is a reason why manufacturers choose a limit for the CPU. If the CPU operates above this temperature it can have dangerous consequences.

You should ensure that you are sticking to the amount that has been set by the manufacturer. Typically, when you reach the temperature limit, this will cause the CPU to shut itself down to prevent overheating.

A CPU that reaches its max temperatures and beyond this will be impacted significantly, and this will likely cause lasting damage to the CPU.

While you can overclock the majority of CPUs, you should never attempt to adjust the temperature limit. The CPU is not intended to work about the max temperature levels, and will become unstable if this happens. This can cause irreversible damage to your build.

What is a dangerous temperature for a CPU?

A dangerous temperature for a CPU will change slightly depending on the type of CPU you own. They will all have varying temperature limits. However, typically anything over 80 degrees, is very dangerous for a CPU.

100 degrees is boiling point, and given this, you will want the temperature of your CPU to be significantly lower than this. The lower the temperature, the better your PC and its components will run overall.

The temperature of your CPU is likely to fluctuate depending on how heaving it is being used. For example, an idle PC typically should run at around 35 degrees. If an idle PC reaches 50 degrees, this is a serious issue.

When the PC is working at its full capacity, it should ideally sit at around 60 degrees. Any higher than this can be dangerous.

Conclusion

Keeping your CPU temperatures at low levels is what makes a happy computer. Improvement in performance and faster response rates are among the things you will benefit from a well-maintained computer.

By following these methods, to experience and achieve lower CPU temperatures will be at hand.
