SP Fan, Multicolor, Single

Product Information

having things away from the fan will make it quieter ied say up to an inch at 100% but depends on fan. its like taking a fan and putting it flat on the table it will make noise and lift it tell the noise reduces However, when we start adding resistance to the fan, the table starts to shift. Any fan specification you see shows a volume of air (CFM or other) the fan can move when unhindered, in free air sitting on your desk. There is always some resistance. The moment I put an AF fan on my case, it is no longer capable of moving 63 CFM at 1650 RPM. It will move less. How much less? No way to know exactly without some precise equipment. Every case and environment is slightly different, but for the most part the volume is not substantially less. Your front grill provides some measure of resistance and the AF fan may only move 57 CFM at 1650 RPM. However, that is certainly more than the 40 CFM an SP120 can move at the same 1650 rpm. The SP fan is less affected by the resistance, but the airflow on the AF is still so much higher and it is the better choice.

The sound level of the Corsair LL is 24.8 dBA. The Corsair QL has a higher sound level which is 26 dBA. At the bottom of the screen, you will see two items labelled Lighting Channel 1 and Lighting Channel 2. These are the two connectors on your Lighting Node Pro or Commander Pro labelled LED 1 and LED 2 that correspond to these. Select the drop-down box next to the Lighting Channel you have your devices connected to, and switch them to either SP RGB Fans, HD RGB Fans, LL RGB fans, ML RGB fans or Lighting Strips. So if you were to use fan B on a radiator as an exhaust (basically no restriction in the front of the fan), shouldn't it work better than the static pressure fan? I say this because both of the fans are still moving AIR which has the same density...etc. Since fan B is able to move the air faster to begin with, shouldn't the air be able to push through the fins of the radiators more effectively than the static pressure fans? 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. Corsair QL and LL use pulse width modulation control. However, the Corsair QL has the fastest PWM, which further reduces the on/off switching. This actually decreases the duty cycle.

due to conservation of energy, that mechanical work is converted into "pressure" pushing the screw forward The Corsair QL looks better from both angles, so you have more options when it comes to RGB light customization. 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. https://www.corsair.com/us/en/Categories/Products/Fans/RGB-%26-LED-Fans/iCUE-QL-RGB-PWM-Fan/p/CO-9050098-WW https://www.corsair.com/us/en/Categories/Products/Fans/RGB-%26-LED-Fans/iCUE-SP-RGB-ELITE-Series-Fans/p/CO-9050109-WW#tab-tech-specs

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.

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. Either let iCUE automatically detect your Corsair fans, or manually select the appropriate product. 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.

Before investing in a fan, make sure it is compatible with your computer case. The Corsair QL and LL come in two different dimensions, 120mm x 25mm and 140mm x 25mm. 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 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 Next, you can press the Lighting Setup option and start adjusting colors. For instance, you can mix two colors and choose a lighting type like solid, gradient, ripple, or wave. 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.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. In the second drop-down box, select how many of each device is connected to your Lighting Controller. 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.

The AF (Airflow) and SP (Static Pressure) have two different blade designs that result in different performance. An AF fan or any other with many, thin, steeply raked blades, is the most efficient for moving air. This is what why we use them. The SP fan by comparison has fewer blades (usually 7) with a flatter and fatter blade. This is a less efficient design and at any given RPM, the AF style blade will move more air. However, the SP style blade has the ability to focus the airflow into a tighter stream and is able to push more air when faced with moderate resistance. This can make it the better choice for areas where you need a focused, direct cooling source or when faced with resistance, like a radiator.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 Air flows is measuring the flow of the fan in an unobstructed area. The rule of thumb is use higher air flow for unobstructed areas like exhaust/intakes and use higher static pressure on radiators. These two models are pretty similar when it comes to fan speed. The LL model has a speed range between 600 and 1500 RPM. Although the minimum speed is 600 RPM, the Corsair LL is not loud.
