Which one should you choose?
Choose Thermalright 92mm Slim PWM Fan if
- You need a fan for a low-profile CPU cooler or a tight case slot.
- You prioritize maximum airflow in a small 92mm footprint.
- You want a silent, non-lighted fan with vibration damping pads.
Choose be quiet! Light Wings 120mm PWM ARGB Triple Pack if
- You are building a standard ATX case with 120mm fan mounts.
- You want RGB lighting effects synchronized via an included hub.
- You prefer a triple-pack value with a dedicated ARGB controller.
Verdict: Choose the Thermalright fan if you are constrained by space or need to cool a CPU cooler directly. Pick the Be Quiet! fans if you are filling standard case slots and want customizable lighting. Each product serves a different physical requirement in your build.
Slim Cooling Versus Standard RGB Fans
Fan Size and Profile
The Thermalright TL-9015 measures 92 by 92 by 15 millimeters. This ultra-thin profile allows it to fit in tight spaces, such as behind downward-facing CPU coolers or in cases with limited depth. The Be Quiet! Light Wings measures 120 by 120 by 25 millimeters. This standard size fits most modern PC cases and radiators. The 120mm fan moves more air generally, while the 92mm slim fan offers unique compatibility for specific compact builds or high-clearance cooler setups. You must choose based on your case dimensions.
Airflow Performance
Airflow determines how much cool air enters your system. The Thermalright fan delivers a maximum airflow of 42.58 CFM. This is efficient for its small 92mm footprint. The Be Quiet! fan does not list a specific CFM value in the provided data. However, 120mm fans typically move more air than 92mm fans. If you need maximum air volume for general case ventilation, the larger Be Quiet! size likely has the advantage. If you need precision airflow in a small area, the Thermalright spec is clear.
Noise Levels
Noise matters for a quiet PC. The Thermalright fan specifies a noise level of less than or equal to 22.4 dBA. This is very quiet for a fan spinning at 2700 RPM. It uses vibration damping pads to reduce friction noise. The Be Quiet! fan lists seven silence-optimized blades to reduce turbulence. It does not provide a specific decibel rating in the data. You can assume the Be Quiet! fan is designed for silence, but the Thermalright fan gives you a concrete number to compare against your tolerance for noise.
Lighting Features
Visual appeal is a key difference here. The Be Quiet! Light Wings includes ARGB lighting with 18 LEDs per fan. It supports multiple colors and modes. The package includes a hub to synchronize up to six ARGB components. The Thermalright TL-9015 does not mention any lighting features. It is a functional fan focused on cooling. If you want a glowing case, the Be Quiet! option is the only choice. If you prefer a clean, unlit look, the Thermalright fan is sufficient.
Quantity and Value
You get different quantities with each purchase. The Be Quiet! package includes three fans and one hub. This is ideal for building a full airflow setup with case inlets and outlets. The Thermalright listing shows a single fan option, though pack variations exist. For a single spot needing cooling, like behind a CPU cooler, the Thermalright unit is precise. For a complete case ventilation strategy, the Be Quiet! triple pack provides more hardware out of the box.
Which Fan Fits Your Build
Compact PC builders needing thin fans
Choose this Thermalright fan if your case has limited depth. Its 15mm slim profile fits behind downward-facing CPU coolers or in tight spaces. The 92mm size and 4-pin PWM connector allow automatic speed control. You get up to 42.58 CFM of airflow with noise levels under 22.4 dBA, keeping your system cool and quiet without taking up much room.
Users wanting RGB lighting and airflow
Select the Be Quiet! option if you prioritize aesthetics and standard case ventilation. This triple pack includes three 120mm fans with ARGB lighting on both sides. The included hub synchronizes up to six components. You get seven silence-optimized blades for high airflow and low turbulence. The 4-pin PWM interface ensures automatic speed adjustments based on your system temperature.
Builders seeking quiet operation in small cases
Pick this Thermalright fan for quiet performance in constrained builds. The liquid bearing design extends service life while maintaining low noise. Its 1.33 mm H2O static pressure helps push air through dense heatsinks. The vibration damping pads reduce friction noise during rotation. You get reliable cooling with a maximum speed of 2700 RPM, making it ideal for small form factor PCs.
