How Does CPU Cooler Work?

In gaming, users prefer using high-quality processors because they are capable of handling the load of heavy games. However, these processors release vast amounts of heat. With the help of CPU coolers, the system tries to dissipate heat and maintain temperature, improving performance. Otherwise, this heat may slow the system’s speed or sometimes cause irreparable damage to the component.

For now, there are a few types of CPU coolers, including air coolers, liquid coolers, exotic coolers, or submerged coolers. All of them use different mechanisms to dissipate heat. 

However, in all these types, the main idea to dissipate heat depends on the basic design, which mainly consists of heat sinks, conductors, and fans. Here is a brief explanation of how these components work together to cool down the CPU efficiently.

When the CPU releases huge amounts of heat during heavy-duty tasks like gaming, heatsinks that sit on the CPU trap this heat, heatsinks are made up of high thermal conductivity metal such as aluminum or copper and consist of numerous fins or pins. These fins are arranged in such a way that gives a block-like appearance and increases the surface area to trap more heat. As the heat passes through the heat sinks, the fan position above the heatsinks blows air across the fins and releases heat outside the system, resulting in the cooling of the CPU.

A thermal paste fills gaps between the CPU and heatsink or heat pipes attached to the CPU, which contains heat-conductive fluid that is also present for efficient conduction between the CPU and cooler. This fluid vaporizes when carrying heat and then reaches the cooler part of the pipe, where it liquefies again.

Now you have understood how the CPU cooler in a PC works, it will be easy for you to understand the explanation to all the queries listed below, especially if you are a newbie.

Do I Need Two CPU Coolers? If not, How Many CPU Coolers do I need?

No! You don’t need two or more CPU coolers if you are running a single processor. However, you should have at least 1 computer cooler to ensure that the processor’s temperature is adequately maintained. As a single cooler is usually enough to do the job, you don’t need to worry about having an extra one. 

But when asking, How many CPU Coolers do I need? If you’re contemplating heavy tasks like overclocking or gaming, you might consider replacing your current cooler with a more powerful one or adding extra fans based on your needs, preferences, and budget.

However, it is important to remember that CPU coolers mainly rely on fans for their air-cooling effects. So, if you find a word such as “multiple CPU coolers” in this article, you can automatically think of it as a CPU fan, as both are interlinked.

Now, let’s take a deep breath and dig out to find out how many CPU fans are sufficient, considering different factors.

Factors To Determine How Many CPU Coolers You Need

Budget:

This is considered to be the first and foremost important factor in installing multiple CPU coolers, as they may require your hard-earned money. So, if you have a limited budget, it would be more economical to opt for a ‌single powerful CPU cooler than investing in multiple CPU fans. However, if you have a higher budget and are using a high-performance CPU, then it totally depends on you to invest in multiple CPU coolers or a more advanced air cooling solution. To find CPU coolers according to your budget, you can check the article Best CPU Coolers for Ryzen 5 5600X.

Case Size:

Suppose your CPU case is small, so the area for the airflow is restricted, resulting in heat. This heat may cause thermal throttling and multiple shutdowns of the computer system. In order to avoid this, adding an extra fan to the system would be beneficial and enhance the cooling effect of the CPU coolers.

The Weather Conditions In Your Region

Another important factor in determining whether you need extra fans is the weather and humid climate. Suppose you’re living in Florida; your CPU may take longer to cool down compared to Seattle as the weather is ‌hotter and more humid, or you can say more tropical in Florida. In such a case, adding extra fans is a wise idea. However, the number of fans you may require typically depends on your needs.

The Build Quality Of Your CPU:

Nowadays, Many modern CPUs come with high-quality and powerful coolers as these high-performing processors are specifically made for heavy-duty tasks such as video editing, gaming, content creation, etc. However, suppose your processor releases heat more than the cooler’s capacity to dissipate. In that case, you might need extra fans for a powerful cooling effect to maintain overall temperature, allowing for smooth processor application.

Overclocking:

For gaming enthusiasts, users prefer overclocking techniques to get a better gaming experience. This can be achieved by pushing CPU and GPU activity to their maximum limit, resulting in increasing system performance. However, this technique produces a huge amount of heat that needs to be released out of the system; otherwise, it may cause permanent damage to the system.

Although adding an extra fan may help to enhance the performance of the CPU, investing in a high-quality computer cooler, such as the AIO liquid cooler, maybe a more suitable choice.

For instance, if you are doing moderate overclocking, a high-end air cooler PC that consists of a large case and powerful fans is a perfect choice. However, for an extreme case, liquid coolers work far better due to their larger radiators and better heat dissipation design.

Are 2 Fans Better Than One?

Having two fans is better than having one, as two fans in the same space provide better airflow circulation. However, this totally depends on the needs of the individual and the compatibility of the CPU case. It is crucial to strategically position CPU cooling fans so they circulate airflow in a way that causes even air distribution throughout the system, resulting in efficient cooling. 

When air from two fans blows over the heatsinks, it helps to dissipate heat from the processor more effectively than one. So, adding one extra fan in the same direction is more beneficial for some users. However, using two fans in opposite directions can create a push-pull configuration. As one fan draws air from the heatsink while the other fan pushes hot air out, this will allow cross ventilation and better heat transfer, resulting in a lowering of the temperature. This setup is particular for users who use programs that put a heavy load on the processor.

Moreover, the use of two fans allows for a quieter user experience. One fan produces more noise due to increased load and runs at a faster speed during intensive tasks. So, if you prioritize a quiet computing environment, you must consider this option.

Are Six Fans Enough for a Gaming PC?

Having six to nine case fans in your setup completely depends on your personal preferences, as it is not a must-have thing to have. Six to nine-case fans offer better ventilation and keep your components cool, especially when users want to push their system’s performance limit during extended gaming sessions or running demanding applications like Adobe Photoshop. It also provides efficient thermal management, but if your case is well-ventilated, you may not necessarily need all six or nine fans.

For instance, if you’re engaged in extreme overclocking, and your processor gets extremely hot and consumes huge power, then adding six to nine fans allows for better airflow and prevents damage from excessive overheating. However, these many CPU fans produce extra noise, which could be a problem for some users. So, in these extreme cases, the highly robust cooler in a PC is the only solution.

Although It is important to look for the available space for fans in the computer case, if your CPU coolers are designed for multiple fan compatibility, then adding multiple fans offers an improvement in the performance of the CPU.

On the other hand, if the processor cooler does not have multiple fan installation provisions, attempting to add six to eight fans may cause crowding in the CPU case. As a result, these fans may interfere with other components, such as RAM modules or motherboard heatsinks.

Moreover, using six to nine fans may require certain factors to consider, including wire management, positioning of fans, and many more. A well-ventilated case with good airflow management is key to maximizing cooling in a PC. 

But if you’re still worrying about high temperatures and the damage they might cause, then investing in a high-quality computer cooler offers better thermal dissipation than increasing the number of fans.

Do I Need 2 Radiators For My PC?

Generally, two radiators are helpful in some cases and depend on the following factors: the type of cooling system, the cooling components being cooled, and the desired level of cooling performance. Usually, high-end CPUs designed for gaming enthusiasts and overclockers utilize liquid cooling systems, such as all-in-one (AIO) coolers or custom water cooling loops, which include radiators to cool down the CPU and other components.

In most cases, a single powerful radiator is enough for efficient cooling. However, for using multiple radiators, you need to determine your needs and the size and type of cooling system. For instance, if you run multiple processors or heavy games that utilize graphic cards, you may require two radiators to cool the CPU and GPUs separately. In addition, if you have a large CPU fan in your setup, you may also require multiple small radiators for efficient cooling. However, if your case does not have space to accommodate multiple radiators, then you can use one large radiator, as it can reduce the complexity of the setup or limit stagnant airflow.

In this article, I have covered almost all the queries and factors to consider whether you need single or multiple CPU coolers. Still, this article would be incomplete if I skipped steps to improve CPU cooler performance, as processor cooler performance is directly related to CPU performance.

How To Improve CPU Cooler Performance 

Here are some steps you can take to improve the performance of your CPU cooler:

Ensure Proper CPU Contact:

The first and most crucial step is to assess the thermal paste or thermal pads between the CPU and the heatsink. An adequate amount of thermal paste fills the gaps, allowing for better heat transfer and ensuring heatsinks are in close contact with the CPU, so it should be assessed following the instructions provided by the manufacturer.

Optimize Fan Configuration:

This factor is one of the crucial steps, as the incorrect orientation of fans alleviates overheating and causes excess noise. Fans should be aligned and identified by arrows. For example, intake fans should be placed at the front of the case, creating positive air pressure by drawing in cool air toward the inside of the case. In contrast, exhaust fans are typically placed at the top or back of the case to expel hot air, and extra fans should be placed on the side panel or bottom to provide extra cooling to specific components. In addition, make sure these fans are attached securely to heatsinks for better CPU cooler performance.

Maintain Adequate Airflow:

Another step to improve CPU cooler performance is to make sure there are no obstructions blocking airflow, such as cables or stacked components. No obstruction allows proper airflow within your PC case, increasing CPU cooler performance. Also, regularly clean the computer cooler and case fans to remove any accumulated dust or debris that may hinder airflow and reduce the cooling effect.

Fan Speed and Control:

Most modern CPU coolers have fan speed control software that optimizes CPU fan speed according to your performance needs. At high speed, fans cause more noise. For instance, if you want to use a PC for basic functions, then lowering the fan will cause no harm to you as you don’t need a powerful cooling mechanism, which will also reduce noise.

Upgrade To a More Efficient CPU Cooler:

If you have tried all the above methods to improve CPU cooler performance but are still experiencing high temperatures or inadequate cooling performance, it would be ideal to consider upgrading to a more efficient CPU cooler.

Conclusion:

For gaming and other high-performing tasks, the CPU cooler plays a significant role in maintaining temperature. With its key components, CPU fans and heatsinks, a computer cooler provides optimal airflow circulation and helps to dissipate heat. 

However, the need for an extra CPU fan or cooler in pc depends on several factors. For instance, you might need to upgrade your cooling solution if you have a high budget and use a high-end CPU for overclocking or operating in hot climates. Whereas extra fans may be beneficial for small CPU cases.
