How Long Does The CPU Last?- Everything About Its Longevity

77 / 100

CPU is a long-lasting part of the computer unless any of its major components fail. The lifespan of a CPU depends on the usage and produced heat. If somehow overheat is produced, the CPU can’t serve long.  So, how long does the CPU last? 

Usually, a CPU serves up to 10 years. Once there is a minor failure in it, it causes total failure. After a certain time, the CPU’s speed can be slowed down. Most of the manufacturers claim that their CPU can serve around 7-10 years. 

However, some factors determine the longevity of the CPU. A perfectly running CPU fan is essential to ensure the long-lasting of a CPU. Besides, avoiding overclocking and overheating provides the CPU with a longer lifespan. It’s time to know more secrets about the longevity of a CPU. 

How Long Does The CPU Last? – Everything you should know

The approximate time for the CPU to last varies depending on some factors. Approximately, a CPU is expected to last for 10 to 15 years. After a decade, a CPU will wear out without any major reason. If you can keep your CPU cool as well as under the perfect maintenance, it can last longer.

It’s not about ensuring the life of a CPU but also getting desired performance from it. Under the optimum temperature and humidity, a CPU can perform smoothly. Nowadays, there are different CPU manufacturer brands. They have different types of processors and the longevity varies according to the company. 

What determines longevity?

Some factors have a strong impact on the longevity of the CPU. Here you know about some of the prime factors. 

No overclocking

Overclocking may satisfy you for a little while but it’s dangerous for a CPU. It means drawing more current and voltage so that the device becomes faster. Overclocking produces excessive heat which is a threat to the CPU. 

To get a longer lifespan from the CPU, avoid overclocking. Overclocking also creates an impact on the performance after a certain time. People get fooled most often after seeing the initial performance after overclocking. 

Sound CPU fan

The CPU fan is one of the essential components of a computer. It keeps the CPU cool and efficient for daily use. Sometimes, the CPU fan stops working and it happens because of the absence of lubricants. 

Besides, lack of power or any wrong internal connection also can affect the CPU fan. A CPU fan keeps the processor cool as well as the CPU cool. So, to get a better lifespan, keeping a good CPU fan is mandatory. 

Fine motherboard

A faulty motherboard affects the lifespan of the CPU. The power may fail due to a faulty motherboard. As a result, there will be a surge in voltage and it causes death to the CPU. You shouldn’t use a faulty motherboard unless you want to lose your CPU. 

No excessive heat

Heat is the main trouble for any kind of processor as well as the CPU. The presence of excessive heat affects the performance of the processor. It’s created by running heavy files on the computer. So, it’s prohibited to do any action which produces some extra heat. 

Updated thermal paste

Thermal paste transfers heat to the heat sink. But, the old thermal paste can’t do this work. As a result, it’s mandatory to have the newest thermal paste. Changing thermal paste regularly ensures the longevity of the CPU. 

How to increase longevity?

Increase your cpu longevity

Increasing the longevity of the CPU is pretty straightforward because it’s the same for all brands. You already know about the factors which determine the longevity of the CPU. Here are some extra tips to handle those factors precisely. 

Never run your computer continuously

Running a computer continuously means its CPU is working back to back. This kind of attempt is suicidal for the CPU. It produces extra heat to the processor inside the CPU which isn’t welcome. However, let your computer take some rest before starting another session. 

Change the thermal paste regularly

Thermal paste should be changed according to the manufacturer’s policy. Modern CPUs come with thermal cut-offs. This technology shuts off the CPU’s work when excessive heat is produced. If your computer needs to replace the thermal paste, do it without delay. 

Check the CPU fan regularly

The CPU fan is nothing but the cooler for your CPU. Keep the CPU fan clean so that necessary air can pass through it to the CPU processor. The CPU can work more efficiently and for a longer time by keeping the CPU fan clean. 

Wipe away dust from the CPU

Dust is a dangerous enemy for the CPU. It creates many internal problems with the CPU. The CPU will stop performing precisely and one day, it’ll stop working. Do you want to face this type of situation? If you don’t then grow up the habit of cleaning dust regularly from the CPU. 

Frequently Asked Question- CPU Longevity

Let’s know about some common questions and their answers on the longevity of the CPU. 

What is the lifespan of a CPU?

Generally, a CPU can last for only 7-10 years. The lifespan of the silicon transistor of a CPU is around 20 years. CPUs get slower after a certain time and after a while, they die. However, the lifespan varies depending on the using style as well as how much CPU gets heated.

Can a CPU last 10 years?

A CPU can last for 10 years. The average lifespan of a CPU is 7-10 years. After a few years, it starts to perform unpleasantly. An inappropriate cooling mechanism can lead the CPU to death. If the CPU doesn’t receive excessive heat, lasting it for 10 years is normal. 

Does a CPU wear out?

Yes, a CPU can wear out in some cases. Overheating is one of the prime reasons. Excessive heat leads the CPU to wear out more rapidly. Moreover, gathering dust on the CPU also affects its performance. Hence, a CPU can wear out.

Now, your question “how long does the CPU last?” must have got proper answers. A specific number can’t be defined to describe the longevity of a CPU. It can last for 5 years, either for 10 years or more. The longevity may vary to different brands in case you have similar care for the CPUs. 

You can’t fix the internal trouble of the CPU. But, you can not let your CPU warm every time. Besides, you also can not let your CPU be full of dust. Regular cleaning and avoiding overheating your CPU must bring some positive results. 

However, you should change the thermal paste from time to time. If the CPU fan is partially or fully defective, you also need to fix the fan. Your prime responsibility is to keep the CPU cool. Following the tips depicted here must be fruitful for the longevity of your CPU.
