The Central Processing Unit, commonly known as the CPU is probably one of the most important, expensive and principal part of your computer.

The CPU can be defined as the brain of the computer as it controls all the major functioning including memory, arithmetic-logic unit and control unit. Extra care of this specific part of the computer is absolutely crucial. 

The CPU is highly prone to heating up when overloaded, which can consequently lead to the overall permanent damage to your computer system. To prevent this from happening, here are 8 ways to keep your CPU temperature low. 

Avoid Overclocking 

Overclocking is when users increase the clock rate of a computer in order to run the CPU of the computer at higher speeds than that set by the manufacturer. This is a common practice amongst gamers who want their computers to function at a faster rate.  

Overclocking can be extremely harmful for the CPU as it pushes the system’s capability to its limit. The change in the speed of functioning of the CPU causes it to overheat which may have harmful and damaging effects to not only the CPU but also the entire computer system. Therefore it is best to avoid overclocking entirely. 

Give Access to Airflow 

While clustered desks may show a signs of a creative mind, they can potentially be harmful for your CPUs. 

You need to ensure that your computer system doesn’t have any obstacles cluttering its airflow. Avoid placing any objects within three inches of your computer in order to give it breathing space and thus reduce the chances of overheating drastically. 

If the airflow to your CPU is blocked, chances are it will struggle to find an avenue to release built up heat, which could cause overheating inside the system. 

Thermal Paste 

One of the most foolproof ways to keep your CPU temperature low is through thermal paste. The mode of function of the thermal paste is that it transfers the excessive heat produced by the CPU onto its cool solution hence normalizing the temperature of the hardware. 

However, all thermal pastes aren’t the same. Only the best thermal paste for CPU cooling is effective in normalizing the temperature of the system. 

Upgrade your CPU Cooler 

Computers tend to have a built in CPU cooler commonly known as a ‘stock cooler’. However their performance is average and is often not very effective in keeping the CPU temperature low.  

There are CPU coolers available in the market that perform far better and are more powerful than the pre-installed ones. They tend to have bigger fans and heat sinks that absorbs up huge amounts of heat from the CPU due to its large surface area.

Change the Location

The location of your computer plays a major role on the temperature of your CPU. If your computer is located in a carpeted room or where your furry pets have easy access, chances are dust and debris will clog the CPU causing it to overheat. 

You should also avoid placing your computer too close to windows or vents because these places are likely to meddle with the internal temperature of the system and are also a potential cause of excessive dust and debris inside the CPU. 

Clean your Computer Religiously 

There are over two billion computers in use worldwide yet the simple concept of cleaning them is alien to many, One of the primary causes of overheating in CPUs is dirty and clogged fans. Dust and debris is prone to settle on your CPU fan no matter how hard you try to avoid it. Overtime the accumulated dust is likely to slow down the functioning of the fan resulting in the CPU to overheat. 

If you clean the insides of your computer, especially the fans, on a regular basis you effectively get rid of one of the major causes of overheating. All you need is canned air to remove all of the built-up dust and dirt on the fans and other parts of the computer. 

Increase Fan Speed 

You may not be aware but sometimes default fan settings are not good enough and are running too slow to keep the temperature of the CPU and other components of the computer system cool. 

There are different programs that you can use in order to increase the revolutions per minute of fans installed inside your computer. A faster spinning fan will automatically get rid of the heat produced in the CPU more efficiently and drastically reduce the chances of overheating. 

Keep your Computer Case Closed 

Many times when we feel that our CPU has overheated we tend to take the case off to cool it down. This is a bad idea. Once the case is off, your CPU and other parts of the computer are exposed to dust and debris that will clog the fans in your computer and consequently result in even more overheating. 

The cases are designed in a way to handle the airflow inside the CPU and prevent it from overheating. 


It’s actually not that difficult to keep your CPU temperature low and with the steps listed above it’s absolutely certain that you will be able to ensure a smooth running of your computer syztem along with drastically increasing its longevity.
