Both fans in this comparison support the same software solution for light customization. The ICUE program allows you to adjust RGB colors on each LED on the fan. This is a very useful feature that can help you create a nice ambiance inside or outside your computer case. Features this other type of screw goes in very slow but it is a lot stronger at pushing into things because moving the same distance forward requires more turns, and more turns = more work done The Corsair QL is easy to set up since it doesn’t have a lighting node core. The Corsair LL needs to be connected to the node placed inside your computer case. So this is not your average day "what's the difference between these two types of fans?" but rather why an airflow fan would still not work well when in a "push" setup through a radiator. NOTE: If you connect 6 QL fans and 4 RGB LED strips to the Lighting Node Pro, you will only be able to select and customize the fans in iCUE.

the reason some people use airflow fans on radiators is because the fin density is very low, so the airflow fan doesn't need much pressure to push air through it. (or pull) I changed out to a different case with better air flow and i am using the same fans now my temps are 82F on the 10TB drives and 75F on the 4TB drives. if youre installing a fan in a very restrictive place, like in front of a bunch of hard drives, then a SP fan will perform better because it will have higher CFM at high mmH2O compared to the AF fan The Corsair ll fans deliver an amazing performance. They support RGB lights which can be adjusted via the ICUE software. Above all, they are rated as quiet fans since the sound levels are around 24 dBA. Conclusion

The WORST Trend In Gaming

RGB lights make your computer look better. But, in addition to RGB lights, there are a few key things to consider before buying a new fan. As mentioned prior, the blades can be optimized for air flow or static pressure. They both will generate airflow and static pressure to some extent. When it comes to static pressure RPM correlates directly to static pressure. The higher the RPM the static pressure will jump. This comes at the cost of noise. If you want to protect your computer components from overheating, you should pay attention to other things such as cooling capacity, fan speed, noise, etc. Cooling

if youre installing a fan in a place with no resistance, then its better to get an airflow fan since the CFM is greater when mmH2O is close to 0 Which one is better? It depends on the application and more often how much fan speed you are willing to tolerate. The AF fan will still move a ton of air at high speeds, but you will have to live with the noise. If you are trying for a super quiet set-up, the SP will fare better with dust filters and radiators at low speed. SP or other blades with a static pressure emphasis go the other direction. There should be a fewer number of blades (usually 7), they are wide with little space between those blades, and their rake is typically rather flat. As such, it is always going to be less capable of moving a volume of air at the same speed as an AF-style fan. However, it is far less impacted by resistance like radiators or dust filters. It also has a more focused airflow cone making it better for directly cooling hardware or pushing air through that radiator. To sum up, if you choose the Corsair LL, you have an extra device to set up. Therefore, the QL model prevails in this segment.Dust is the main obstacle to dissipating heat from components such as the processor or motherboard. In specific circumstances, these components become too hot, and fans start rotating faster to reduce the high temperature. This leads to higher noise levels. As such, it provides more options for customization and lighting. LEDs are placed on both sides of the fan. So, you can illuminate both the inside and outside parts of your computer case. Another thing to consider is static pressure. Static pressure is the ability of a fan to push air through different environments such as filters, radiators, etc.

The ICUE also allows you to light up the inner ring, outer ring, and little nodes inside the Corsair fans. The speed of the Corsair QL fan ranges from 525 to 1500 RPM. In other words, if your computer components are too hot, the QL model will increase its speed up to 1500 RPM. The company says there could be an oscillation of ± 10% RPM when it comes to the maximum speed. Keep in mind that high RPM could also mean high noise, although this is not the rule. Sometimes dust inside your computer case can cause your fan to rotate faster. Also, make sure your processor has enough thermal paste to dissipate heat properly. LL and QL are ARGB, adressable RGB which means you can make animations for each LED and color. So the price is for maybe how many LEDs there are on the fans, and if it's RGB or ARGB, also what type of motor the fan is using and pricing high because why not.for a radiator, you can use both fans as long as the radiator isnt too restrictive, due to the fact that radiators are not a solid piece of metal, air actually goes through them When comparing the Corsair QL and LL official specifications, we see that the QL model delivers more noise. The Corsair QL sound level is 26 dBA. However, the sound level of the LL model is 24.8 dBA.
