In recent years, several customers have complained that their CPU temperature has increased after switching to a different cooler. When computers overheat, the central processor unit (CPU) is running too hot most of the time.

It may occur for various causes, including a lack of ventilation, dust accumulation, or faulty components. Whenever you find that your computer is running hotter than usual, you will want to know how to monitor the temperature of your CPU.

In this post, we have discussed why your CPU gets so hot when after changing the cooler. In addition, we will share several ways to maintain your computer’s temperature at a reasonable level.

So let’s get started with the fundamentals.

Why Is It Necessary To Check The CPU Temperature?

The central processing unit (CPU) is in charge of carrying out the instructions received from the hardware and software. When it becomes too hot, it may do significant harm to your electronic equipment. 

We recommend you check your CPU temperature regularly. It ensures you that you are not causing any extra damage to your computer.

What Is The Optimum CPU Temperature For Your Computer System?

The general recommendation is to maintain your computer’s temperature below 60°C to keep it in the best possible condition. Anything below this temperature range can cause any harm to your computer.

Reasons Behind CPU Temperature Increase after Changing Cooler

Many factors may contribute to the overheating of a computer’s central processing unit (CPU). An overheated or filthy CPU cooler is one of the most frequent problems that may cause excessive temperatures in your computer. 

Other factors include insufficient ventilation or cooling in the case. In some instances, the high ambient temperature in the room may also contribute to the overheating of the CPU.

1. Inappropriate Cooler

The main reason is that your cooling system is not functioning correctly. As a result, consider investing in a suitable CPU cooling. The one that comes with the processor in the package is a piece of junk. You can purchase an excellent one for as little as $10. That should help to keep your computer’s processor cool.

2. Not Properly Oriented

Another reason is that you have not adequately placed your new cooler. You will have to take it out again and wipe off the thermal paste before trying again. It’s either not seating well, or you overloaded it with the thermal paste.

How to Reduce CPU Temperatures?

Now, look at some methods discussed below, which we can use to maintain our CPU temperature.

CPU Temperature Increase After Changing Cooler

1. Proper Cable Management

The significance of maintaining a clean cable management system can often overlook. The fact that cables take up a significant amount of space contributes to their poor air circulation. Cleaning out your computer’s connections is an excellent method to improve airflow by allowing them to breathe more freely.

2. Proper Place for Computer

One of the most frequent reasons for higher CPU temperature has something to do with the location of the computer system. If it is put in a poorly ventilated area, the likelihood of experiencing more significant temperatures increases.

Despite the well-organized cable management and appropriate ventilation configuration, temperatures continue to rise. Make sure you relocate your computer to a well-ventilated location as soon as you notice that it is having difficulties.

3. Keep the Case Closed At All Times

Over the years, there has been a debate whether having an open computer system is preferable to having a closed computer system. It may seem reasonable since an open case allows for more airflow, but it also collects a more significant amount of dust.

When you choose a closed computer case, you can be sure to increase ventilation while also keeping dust away. It also encourages and guarantees that you will be less inclined to clean a computer regularly.

4. Maintain Clean Environment

Please take a peek inside the case by opening it up. If the different circuit boards on the computer coat in dust, switch off the computer and give them a thorough spray with compressed air to remove the dust off them. Blot out the regions surrounding the hard drives, and wipe out the area around the power supply as well.

5. Use of Computer Stand

The usage of a computer stand is an excellent method to improve ventilation while also protecting your computer. The easiest way to prevent your laptop from suffocating is to place it on a firm and level surface. Laptop stands also allow you to position your computer at the most optimum angle for cooling.

6. Purchase New CPU Cooler (Optional)

If you are still experiencing problems with your computer’s cooling, upgrading to some new fans and a new cooling system may be time. In addition, you can install a cooling water system to keep your equipment cool.

However, this is the optional method. First, you can try the other forms, and if it doesn’t work for you, you can think of changing the cooler again.

Does Cooler CPU Temperature Affect Performance?

Heat, cold, and dust are examples of environmental factors that may harm and degrade a computer’s functionality. 

Temperature variations, both external and internal, are particularly detrimental to computer performance. However, it is a fact that a computer is more sensitive to heat than to cold.

Cold temperatures are not as hazardous to a computer as overheating, but they may still cause issues if they are extreme.

 When computers are kept unplugged for an extended period, their internal components may get damaged due to the heat generated when the computer turns on again.

Therefore, before turning on computers that have been kept at cold temperatures, you should allow them to warm up to room temperature before using them.


You should now be aware of the potential causes of a high CPU temperature. The methods given make it simple to comprehend how to decrease the CPU temperature.
