Corsair QL vs. LL: What’s The Difference?

When looking for fans to install in your computer case, knowing what the different types of fans mean and how they perform under various conditions is essential. There are multiple fans that you can get from the market, but it is important that you know if they are suitable for your system or not. Especially if it’s your gaming rig that you are preparing. That’s why in this guide, we will compare the Corsair QL and LL fans from Corsair to know if they are suitable for you or not.

Corsair QL and LL are both from Corsair, which is a pretty well-known company and create some high-quality products. But if you have to choose anyone from their fans which one do you pick? That is what we are going to discuss here so that you can make your decision easier. 

Corsair QL Vs. Corsair LL

One of the most important things to do before buying a fan for your system is to know how much space you have. Fans come in different sizes, and not every fan can fit into your system. Thus, before going on a fan hunt, it’s important to open your computer up and note down the space that you have for the fans. While we are talking about Corsair QL and LL, know that they come in two different sizes. You can get 120mm and 140mm, but that decision you will have to make according to the space your system has. 

The Corsair LL and QL Series fans are both low-noise, high-performance RGB fans. If you need a fan to cool your computer off or to move some hot air from one side of your case, then either one will suffice for what you need. However, you may wonder why we have put them together in comparison if they’re both quite similar. 

That is because despite having a ton of similarities, their skill has some major differences that can change everything about your experience. Thus, without further ado, let’s dive right into it and understand which one is the best option for you. 

Corsair QL

The Corsair QL is a new line of fan coolers from the company. It’s designed to offer quiet performance, easy installation, and maintenance. It also comes with an integrated RGB lighting system that can be customized using the CORSAIR iCUE software. 

The benefits of these coolers are that they are easier to install and maintain, have a quieter operation than air-cooled solutions, and have a more customizable lighting system. This comes in handy for gamers who want to maintain the gaming aesthetic with the hardware they own. 

The fan features 34 RGB LED presets that go in four loops giving the system a catchy look. Moreover, it comes in two different sizes: 120mm and 140mm; thus, before buying, you will need to make sure which one is suitable for you. 

  • Features 100s of RGB LED lights at your service.
  • Simple installation and maintenance.
  • Decent airflow.
  • Somewhat expensive.
  • A bit noisy.

Corsair LL

Right off the bat, Corsair LL gives one of the best cooling performances that you can expect. Corsair LL fans feature a hydraulic bearing and a pretty constant and static air pressure flow at any speed. It features 9 blades which are made of durable, lightweight polymer, these fans will make sure that your system is running cool even at a heavy load. 

They also come in two different sizes: 120mm and 140mm; thus, knowing which size you want is important. Moreover, this fan comes with 16 RGB LED lights on it; thus, you can customize the resets according to your own liking using the CORSAIR Link software. But for that, you will need to buy the Corsair lighting Node pro. It is a controller, which does not come with the single fan pack, but if you are getting the three-fan pack, you will get one free with it. 

  • Better cooling performance.
  • Relatively affordable.
  • Cool aesthetics.
  • LED customization needs a separate controller.
  • Complex installation.

What is the difference between Corsair ML and LL?

There are a couple of features that set both the fans apart. Below we will discuss the differences and similarities between Corsair QL and LL so that you can make a reliable decision between both of them. 

Airflow Pressure

There are multiple things that combined affect the airflow pressure of the fan. These factors include the PWM and static pressure. If you have no idea what these are, there is nothing to worry about, as we are here to explain. Both the QL and LL come in two sizes, as we have mentioned above. Thus size is not the factor that will make a change between them. This is where PWM or pulse width modulation comes in.

PWM is the technique that affects the duty cycle of the fans. There is no need to go in-depth, just know that the lower the duty cycle, the better. And in our case, Corsair QL features a lower duty cycle than the Corsair LL. Another major thing that counts is the static pressure, which measures the force of the air through different objects that the fan creates. 

In this case, the lower the static pressure a fan has, the better it will be. Thus, Corsair QL features 41.8 Cfm, and Corsair LL features 43.25 Cfm. Depending on this, you can understand which has a better airflow pressure between these two.  

Lighting and Presets

Unlike the LL model, the Corsair QL stands out in this section due to the customization of LED lights that it comes with and how easy it is to install. Both the fans feature LED lighting and look appealing, especially in a gaming system but what sets them apart is the node that the Corsair LL comes with. 

To handle the lights, you will need to install a separate Node in your system if you are using Corsair LL, which takes up space. This is not the case with Corsair QL; thus, its installation is much more simple and less space-consuming. Moreover, QL comes with lights on both of its sides. Thus, the illumination effect; that it gives to the inside part of your system just changes the aesthetic game. 

Know that both fans use the same light customization software, which is the Corsair iCUE software. It is easy to navigate if you get the hang of it and allows you to create multiple lighting effects for your fans. With that out of the way, both will give you an amazing visual lighting effect. But if you are choosing the Corsair LL, make sure that you have the extra space for the Node. 


The cooling that the fans provide depends on their RPM. If you don’t know what RPM is, it means the rotation per minute. This means it calculates how many times a fan completes its rotation in a minute. It depends on the speed as well, but the more RPM a fan has, the better cooling effect it will provide. 

Now the minimum RPM that the Corsair QL features are 525, whereas the Corsair LL features an RPM of 600. Thus, it’s better at cooling your system. However, that does not mean the QL is not good at cooling, it’s just that Corsair LL is a bit better in this forte.   

Noise Control

One thing that affects the noise of the fans is how fast they are moving. Another thing that makes the difference is the dust in your system. That is because when dust enters the processor or the motherboard, chances are that it will make your system heat up more frequently. Thus, making the fans move faster and end up creating more noise. 

Moreover, the Corsair QL and LL fans come with the same blades but are not the same. With that in mind, the next difference between these two types of cooling is how they operate. The noise level of LL will be higher because the fan runs at a higher RPM. 

On the other hand, a QL fan operates at a lower RPM, so it should be quieter than an LLs model would be. But that’s not the case since Corsair QL has a noise level of 26dBA and LL has a noise level of 24.8dBA. This means that an LL is better for noise control while still providing you with a better reliable cooling performance.

Speed and Power consumption

One of the simple things to understand is that the higher the RPM, the higher the power consumption will be. Corsair QL has a lower RPM than the Corsair LL, but the maximum RPM for both fans is 1500 RPM. This means that when it comes to dealing with hot temperatures under a heavy working load, both the fans will have the same threshold and relatively same power consumption. 

But if the system is running smoothly without any working load, the QL will run at525 RPM. Thus, lower power consumption whereas LL can’t go below 600RPM means that power consumption will always be relatively higher.

Processors that Corsair QL and LL are compatible with

The first thing to consider when choosing a Corsair fan is the type of motherboard you have. If you have an older Intel motherboard that uses LGA775 pins, it will not be compatible with the newest Intel processors; therefore, cannot use an L-series cooler. 

If this is the case, there are still many other options for cooling, such as air or water cooling solutions. It is also important to note that if you are using AMD processors, both coolers can be used, and there are no limitations. You should also keep in mind whether or not your PC case has room for an L-series cooler, as they take up quite a bit of space.

Is QL better than LL Corsair?

The Corsair LL and the Corsair QL are both 120mm/140mm RGB fans, but some significant differences in the design set them apart. One of the most important differences is that while both can get to the same maximum power consumption, their power consumption at lower workloads is quite different. 

The other significant difference between these two fans is their lighting modes. The Corsair LL has 16 different lighting modes for various games, and for each one, you can set three colors for your fan to cycle through using one of four different speed settings. While the Corsair QL features 34 different lighting modes, including LEDs on either side of the fan. 

What does LL mean to Corsair fans?

LL stands for Light loop, which is Corsair’s term to indicate how many loops a fan has. The corsair LL features two loops one on each side of the fan. 

What is the difference between Corsair ML and LL?

The most common question is the difference between Corsair ML and LL. They are two different fans but have a lot of similar features. The only major difference between the two is LED lighting. Both are RGB fans but ML features better-LED modes giving you a more aesthetically pleasing look. 

What does QL stand for, Corsair?

The Corsair QL or Quad loop means that the fan features four loops. This means that, unlike Corsair LL, which features one loop on each side, you will get two loops on each side with Corsair QL.


The differences between the two might seem minor, but they can hugely impact how you game. Consider your priorities and what you want to use the fans for when deciding. Both are visually appealing, but the cooling performance of Corsair LL is a bit better; then again, the power consumption is a bit higher as well. Thus according to your priorities, choose the best one between Corsair QL and LL.
