How to Pick the Best PC Fan: Step-by-Step

A PC fan plays a crucial role in maintaining low temperatures and preventing overheating issues. This component is much needed in CPUs that perform heavy-duty tasks.

However, the specs and capabilities of the fan will determine if it will adequately serve your computer’s needs. Here are the major factors you must consider when selecting the best PC fans:

  • 4-Pin or 3-Pin (PMW)
  • Speed
  • Size
  • Fan Noise
  • Air Flow Capacity
  • Power Consumption
  • Aesthetics

Now, let’s explore each in more detail.

4-Pin or 3-Pin (PMW)

While searching for a good fan, you have the option to choose between a 3-pin or 4-pin. The standard 3-pin fans comprise tach, power, and ground wires, which relay information to the software or motherboard.

The 4-pin has an additional room for Pulse Modulation Control (PMW). This feature enables users to adjust the fan’s speed through the fan control software or motherboard. The 4-pin fans are a better option because they give users more control when cooling their CPUs.

Speed

The speed of the PC fans is measured by Revolutions per Minute (RPM). RPM refers to the number of times the fan rotates in a minute. Fans with a higher RPM are suitable for heavy-duty computers. The many rotations provide a massive inflow of air through the system. This provides better cooling for your CPU.

Size

The PC fans also come in different sizes. You will find fans with sizes ranging from 80mm to 92mm, 120mm, 140mm, and 200mm. The most popular size for modern fans is 120mm. Going for larger fans is an excellent idea because they supply more air to the CPU, especially if they run at the same RPM as smaller ones.

Since they will rotate less than smaller fans, their noise levels will be lower. You should also check the fan’s compatibility with your CPU and ensure it fits in your computer before selecting it.

Fan Noise

Most PC owners can easily overlook this factor, yet it is very significant. Higher fan noises can be a nuisance, especially in an office setting. Therefore, if you love working in silence, consider the decibel level of the fan before choosing it. Manufacturers usually indicate the dBA levels of these machines. Hence, opt for a fan with the lowest dBA.

Air Flow Capacity

The amount of air the fan pushes through your PC determines how well it will keep it cool. The amount of air the fans distribute is measured in Cubic Feed/Minute (CFM). Fans with the best cooling performance have a very high CFM. Therefore, they will ensure a constant supply of more air into your CPU to curb overheating.

Power Consumption

While using the PC fans, they will consume your energy too. Therefore, you must check the power consumption of these machines before selecting the one to purchase. 

Aesthetics

The fan’s aesthetics don’t affect its performance. However, it improves the appeal of the fan to the users. Some fans come loaded with RGB lighting, which makes them more appealing. Others stand out because they have LEDs installed by aftermarket manufacturers. Selecting PC fans based on aesthetics depends on the buyer’s preference.

What to Know Before Buying the Best PC Fan

Purchasing PC fans is a susceptible investment as it determines the reliability of your computer. If the fans don’t function effectively, they will limit your CPUs performance. Here are the things to know before purchasing PC fans.

PC Fan’s Features and Your Needs

Before buying the fans, consider their features and your needs. A powerful PC fan is essential if you are a heavy computer user. If you fall in this category, you need to get a fan with a higher RPM and airflow capacity to blow enough air into your CPU for hours without developing any technical issues.

The Brand

Make your choices based on the brand of the PC fans. Several companies are manufacturing this equipment. However, some are renowned for delivering the best fans for cooling CPUs.

You will never go wrong buying fans produced by reputable companies. The best brands also give a lengthier warranty period for their fans as proof of their reliability and durability.

Reviews of Other Users

Never ignore the opinions of other users before buying PC fans. Some people take time to post reviews after using these fans. Fortunately, reviews are easily accessible online.

Therefore, commit to reading them to know more about the fans. Don’t risk buying fans with innumerable negative reviews from other users. Since most of those devices didn’t meet the expectations of their users, they may be unreliable in cooling PCs.

Cost

Don’t be deceived into buying a costly PC fan to get more value from it. Writing off affordable fans as unreliable is the greatest mistake most people make.

You can find budget-friendly PC fans that deliver impressive performance. Unless you have the money for high-end fans, consider other options with a track record of reliability and excellent performance in cooling PCs. 

Using the Best PC Fans: What It’s like

As long as you are using PC fans, you will never experience overheating issues. These fans can continuously push massive amounts of air through your CPU while you’re using it.

By doing this task tirelessly, they ensure your PC operates at a very low temperature. These fans run at very high RPMs to deliver more airflow capacity to your computer. Their RGB lighting adds beauty to the computer. These fans come in different sizes and can fit any PC perfectly.

These fans will enable computers to perform optimally. By minimizing heating, they also boost the PC’s longevity. You will never repair or replace your CPU’s internal components due to heating issues.

PC fans also enable gaming enthusiasts to enjoy their games to satisfaction as they can play for many hours without interruptions caused by overheating. Therefore, buying a good cooling fan is essential for every heavy-duty PC owner.

Frequently Asked Questions

What are PC fans, and why are they important?

PC fans are computer components that circulate air inside the computer case, helping to cool down the components and prevent overheating. They are important because overheating can cause damage to computer hardware, shorten its lifespan, and cause it to run slower or even crash.

By keeping the components cool, PC fans help to maintain optimal performance and extend the life of the computer.

What is the perfect size for a PC Case fan?

The best size for PC fans is 120mm. Although 140mm and 200mm fans are popular, most CPUs support 120 mm-sized fans. However, the compatibility of the fan with the PC will determine the suitable size for you.

Is the performance of the fan affected by RGB lighting in any way?

No. RGB lighting doesn’t affect the fan’s performance, whether negatively or positively. The RGB lighting doesn’t share power with the fans. Hence, the fans will receive the voltage needed to power them effectively.

Will I get more value if I purchase high-end PC cooling fans?

Yes. The most expensive PC fans have impeccable durability, low noise levels, better airflow, and enhanced aesthetics. They will give you more value while satisfying your PC’s cooling needs. However, you can also find some budget-friendly options that provide quality service.

How do I install a PC fan, and what tools do I need?

To install a PC fan, first, ensure that the fan is compatible with your computer and that you have the necessary tools, such as a screwdriver, pliers, and thermal paste. Next, locate the fan mounting location on your computer case and remove any necessary components that may be blocking it.

Then, insert the fan into the mounting location and secure it in place using screws. Finally, connect the fan to the appropriate power source on your motherboard and apply thermal paste to the CPU before reattaching the heatsink.

It’s important to follow the manufacturer’s instructions carefully and take necessary precautions, such as turning off the power to your computer, to avoid damaging any components.
