QL vs LL Corsair

Corsair QL VS Corsair LL – Which One Provides The Best Cooling System? 

Corsair is a famous name in the computer parts industry. Besides the computer-making industry, many of us now prefer to customize our own PC. When it comes to the cooling system, the Corsair fan serves the best. 

Corsair offers the best RGB fan in the market. They are updating their products in structure and performance. QL and LL series fans are examples.

120mm fan of Corsair QL and LL series is the most popular. Though QL & LL fans share most of the features, they have some differences in performance and design. 

Our Corsair QL VS LL article will show you the comparison and contrast between these two pc fans. Let’s jump into that and find out which fan makes your pc cooler. 

Corsair QL VS LL PC Fans

Corsair fan is popular for their excellent performance and design. Corsair LL series and QL series fans almost have the same features in case of performance and design.

The primary difference between QL fans and LL fans is in illumination, frame, airflow, and sound capacity.

QL fans have a more spectacular lighting system and sound capacity than LL Fans. QL offers a semi-transparent background frame, whereas LL offers a front & back holder. Also, the QL fans supply less airflow pressure than LL fans. 

However, both QL and LL series fans have hydraulic bearing types, a lighting node pro, and an RGB fan hub. Also, they both are PWM fans (Pulse width modulation).

Corsair QL120 VS Corsair LL120

Among QL and LL series fans, QL120 RGB fans and LL120 RGB fans are widely known. Their differences and similarity represent the comparison and contrast of QL and LL series fans more clearly. 

So, let’s see their comparison chart.

Now it is time to go into the deep and explore the details. 

Which Fan Contains Better Structure?

Corsair QL120 VS LL120

Regarding structure, the two fans are not so different. QL and LL series fans share the same size structure. They both are 4.72 inches in height and width. In addition, they both are 0.98 inches in depth. 

However, the corsair LL series fan is lighter than QL in weight. A LL series fan is a better case fan than a radiator fan with a front & back holder. 

On the other hand, after the latest update, QL RGB fans now have a minted semi-transparent background set up.

Which Fan Offers A Better Design?

If we look at their constructive design, the RGB fans share similar design types. 

  • They both have hydraulic bearing types. 
  • They both have pulse width modulation. 
  • They both have slim and strong blades. 

However, they both offer a lighting node pro and an RGB fan hub. But, QL120 RGB PWM fans combine the lighting node pro and RGB fan hub in one unit.

Which Fan Has Better Fan Speed?

RGB fans

Fan speed is essential because the cooling significantly depends on it. Apparently, an LL Corsair RGB fan rotates more than a QL RGB fan per minute. 

On average, an LL120 RGB PWN fan rotates 600-1500 (10% +/-) per minute. On the other hand, an iCUE QL120 RGB PWN fan rotates 525-1500 (10% +/-) per minute.

Which Fan Manages Better Airflow Pressure?

Better airflow pressure=better cooling system. You need to check the airflow pressure because it develops the performance of your CPU as well. 

LL series fans manage airflow pressure at 43.25 cubic feet of meters. On the other hand, QL series fans manage airflow pressure at 41.8 cubic feet of meters.

Which Fan Has Better Lighting?

The lighting effects have made these two fans significantly different. A QL Corsair RGB fan has better PC spectacular lighting than a LL Corsair RGB PWN fan. 

Let’s see the difference in a table. 

Corsair QL RGB PC Fan Corsair LL RGB PC Fan
Has 34 LED addressable individual light settings Has 16 addressable individual light settings
Takes 13 volts at maximum Takes 13.2 volts maximum
Has inner, outer, and backside lighting  Has only inner and outer lighting 
Offers lighting node core  Offers lighting node pro 
Has four distinct light loops  Has two separate light loops

As it is defined that the QL series has the best lighting, how about we have a look?

Which Fan Makes Less Noise?

Noise is a big factor regarding PC fan performance. Besides cooling the system, Corsair fans are also famous for creating less noise. 

If you compare the data number, QL fans are one step forward than LL fans. QL fans have a sound capacity of 26 decibels A. In contrast, LL fans have a sound capacity of 24.8 decibels A.

We have already mentioned that LL fans have more speed than QL fans. Due to more speed, LL fans technically make more noise than QL fans. 

Which Fan Is Easy To Install?

Which Fan Is Easy To Install

The installation process is relatively easy for both fans. Most of the installation tasks are identical for both fans. Even a 140mm fan follows the same process.

You can check the QL series manual and LL series manual to understand how easy the tasks are. 

Which Fan Is More Expensive?

Comparatively, Corsair PC fans are a little bit more expensive than the other fans on the market. But the brand has fair reasons behind this. That is why their website stays sold out most of the time. 

Comparing QL and LL, QL fans are more expensive than LL fans. The extraordinary lighting effects settings are responsible for this price difference.

You can check out the QL120 RGB fans and LL120 RGB fans on Amazon. This will help to compare the products and the price as well. 

Corsair ML VS QL & LL

Corsair ML series fans are also famous in the market. ML fans are more futuristic and advanced than QL and LL fans. It uses magnetic technology to perform. 

However, ML fans are the fastest in the cooling process with their great thermal compound. They have 75 cubic feet meter airflow pressure too.

Regarding fan speed, ML fans are not near QL fans or LL fans. ML fans have 450 RPM (rotation per minute) only. But it has made the fan less noisy. 

ML focuses more on advanced technology and noise control than lighting effects. It only has four RGB lighting settings. Overall, ML fans are next-level PC fans in budget. 

Let’s see the lighting difference between them.
