Corsair 120mm Fan Buying Guide: Cooling and Style Recommendations

A PC that overheats or sounds like a jet engine taking off is a common problem for gamers and PC builders. Proper cooling is essential for the performance and lifespan of your components. A Corsair 120mm fan is often a popular choice for improving airflow inside a computer case. But with different series like LX, RX, and QX, making a choice can be difficult.

This article will help you make an informed decision. We'll look at the key specifications and highlight several popular models, so you can find the right fan for your system.

What to Look for When Buying a 120mm PC Fan

Before you buy a computer fan, it's helpful to understand a few technical terms. This will help you translate the manufacturer's specifications into what they mean for your PC.

1. Airflow vs. Static Pressure

Not every fan is the same. Performance is often expressed in terms of airflow and static pressure.

• Airflow (CFM or m?/h): This indicates how much air a fan can move in an open space. High airflow is ideal for a case fan that blows air into or out of the case without obstruction.
• Static Pressure (mmH2O): This measures how forcefully a fan can push air through an obstacle. High static pressure is crucial for fans mounted on a water cooler's radiator or a dense CPU heatsink.

So, choose a fan with high airflow for general case cooling and one with high static pressure for radiators.

2. PWM Fans for Quiet Operation

The term PWM fan stands for 'Pulse Width Modulation'. This means the fan's speed can be precisely controlled via the motherboard or a controller. As a result, the fan only spins as fast as necessary. During light tasks, your computer remains pleasantly quiet, and during demanding games or workloads, the cooling scales up. If you're looking for a quiet PC fan, PWM support is an important feature.

3. The Convenience of Corsair iCUE LINK

Cable management is one of the biggest challenges in PC building. The Corsair iCUE LINK ecosystem is designed to tackle this problem. Instead of connecting each fan separately for power and RGB, iCUE LINK allows you to connect multiple fans together with a single cable. This results in a much cleaner build and significantly simplifies installation. All connected components can then be managed through the iCUE software.

Frequently Asked Questions About Corsair Fans

What is the difference between the Corsair LX, RX, and QX series?

In short:

• LX Series: A balanced choice with a focus on a good mix of airflow, static pressure, and bright RGB lighting.
• RX Series: Optimised for maximum airflow at the lowest possible noise level. Often available without RGB for a performance-oriented, subtle look.
• QX Series: The premium line with the most RGB LEDs, high performance (especially static pressure), and extra features.

Do I need a separate controller for a Corsair RGB fan?

For the newer fans that use the Corsair iCUE LINK system, you will need an iCUE LINK System Hub. This hub is often included in a 'Starter Kit' (like with the QX120 above) but is also available separately. The advantage is that you can connect up to 14 iCUE LINK devices to a single hub, which greatly simplifies cable management. Older Corsair RGB fans often use a Lighting Node or Commander Pro.

How many 120mm fans do I need for my PC?

This depends on your case and components. A good baseline for a standard ATX system is:

• Two or three fans at the front for cool air intake.
• One fan at the back for warm air exhaust.
• Optionally, one or two fans at the top, also for exhaust.

For high-end systems with powerful components or for water cooling with large radiators, more fans may be necessary.
