- 4-pin PWM connector for automatic speed control
- 47.6 CFM max airflow at 1500 RPM
- Silent operation at ≤23.2 dBA noise level
Who it fits
Good fit for
You should consider this fan if you are building a white-themed PC and want seamless ARGB lighting on both sides. The 120mm size and 47.6 CFM airflow make it suitable for standard cases or as a secondary fan for CPU air coolers. The PWM support ensures quiet operation for office builds or low-noise gaming rigs. The slim light bar fits well with modern aesthetic standards, enhancing the visual appeal without requiring complex setups.
Who should skip it
Skip this option if you need high static pressure for thick radiators or dense filters. The 1.31 mmH2O static pressure rating is moderate, prioritizing airflow over resistance. If you require higher airflow for intensive cooling tasks, look for fans with higher CFM ratings. Additionally, the listing recommends chaining fewer than six fans in series. If you plan to use many fans together, you may need a separate hub or controller to manage the ARGB signals effectively.
Verdict: The Thermalright TL-S12R X3 offers solid airflow and dual-sided ARGB lighting for white-themed builds. It suits users who prioritize aesthetics and moderate cooling performance over high static pressure.
Thermalright TL-S12R X3 Key Specs
Fan Size: 120mm
This is the standard 120mm form factor, measuring 4.7 inches on each side. You will find this size in most modern PC cases and CPU coolers. It offers a balance between airflow capacity and physical footprint. If your case has 120mm mounting holes, this fan fits directly without adapters. It is the most common size for general case ventilation and radiator mounting.
Max Fan Speed: 1500 RPM
This value indicates the maximum rotational speed of the fan blades. At this speed, the fan moves the most air but also generates the most noise. The listing notes a tolerance of plus or minus ten percent. You should expect the speed to vary if your motherboard controls it via PWM. This ceiling speed helps you gauge the upper limit of cooling performance.
Max Airflow: 47.6 CFM
CFM stands for cubic feet per minute. This number tells you how much air the fan moves in one minute. A value of 47.6 CFM provides moderate airflow suitable for standard case intake or exhaust duties. It is not an extreme high-airflow model, but it is sufficient for general cooling. Compare this against other 120mm fans to ensure adequate air exchange for your specific case volume.
Noise Level: ≤23.2 dBA
This spec lists the maximum sound pressure level in decibels. A rating of 23.2 dBA is considered very quiet for a computer fan. You will likely not hear this fan over typical background room noise. This makes it suitable for bedrooms or quiet office setups. Note that noise increases as speed increases, so this is the peak value at maximum RPM.
Static Pressure: 1.31 mmH2O
Static pressure measures the fan's ability to push air through resistance. This value is measured in millimeters of water column. A reading of 1.31 mmH2O indicates moderate ability to overcome resistance from dust filters or dense heatsink fins. It is adequate for standard case airflow but may be less ideal for thick radiators compared to high-pressure models. Use this to judge compatibility with obstructed airflow paths.
Connector Type: 4-pin PWM
This connector allows your motherboard to control the fan speed automatically. The fourth pin sends a pulse-width modulation signal. This enables dynamic speed adjustments based on system temperature. You do not need manual speed controllers. Ensure your motherboard has a 4-pin fan header available. This connector type is standard for modern PC cases and provides precise thermal management.
Build Quality and Physical Layout
According to the listing, the Thermalright TL-S12R X3 features a pure white design. This finish is intended to match white-themed PC builds. The fan includes slim round ARGB lines on both the front and back. These 0.6mm light strips use UPT process technology. This creates a seamless lighting effect. You can connect up to six fans in series for uniform illumination.
The unit measures 120 by 120 by 25 millimeters. It weighs 3.53 ounces. The frame uses soft silicone feet. These reduce vibration and noise during operation. The blades are oriented for reverse airflow. This means the motor sits on the side facing you when mounted. This layout is useful for pushing air through radiators or filters.
Controls are handled via a 4-pin PWM connector. The fan draws 0.15A of current. It adjusts speed automatically based on motherboard signals. This allows the fan to run quietly at low loads. It reaches 1500 RPM for maximum cooling. The design is compact enough for CPU coolers. It also fits standard case mounting points. The white aesthetic and reverse orientation make it suitable for visible installations.
Installation and Daily Operation
You install this fan using a standard four-pin PWM connector. This cable plugs directly into a motherboard header that supports PWM control. The listing confirms the fan includes soft silicone feet. You attach these to the case or heatsink frame. These feet help reduce vibration and lower noise levels during operation. The fan adjusts its speed automatically based on system temperature. You do not need to set a fixed speed manually. The maximum speed is 1500 RPM, which generates 47.6 CFM of airflow. This speed also produces a noise level of 23.2 dBA. The reverse blade design allows you to mount the fan for optimal airflow direction. You can use this unit as a case intake or exhaust. It also works well with CPU air coolers. The dual-sided ARGB lighting connects to your motherboard’s addressable header. The listing recommends connecting fewer than six fans in series. This ensures the lighting controller can manage the signal correctly. The slim 0.6mm light strips provide even illumination. You get a clean look for white-themed builds. The fan weighs 3.53 ounces. It fits standard 120mm mounting holes. You can pair it with other Thermalright products for a cohesive setup. The PWM function ensures the fan runs quietly when the system is idle. It speeds up only when cooling demand increases. This makes it suitable for continuous daily use without excessive noise.
Before You Buy This Fan
You should verify your motherboard has an available ARGB header. The listing recommends connecting fewer than six fans in series to avoid overloading the controller. This ensures stable lighting without signal degradation. You must also check your case for 120mm mounting holes. The unit measures 120 by 120 by 25 mm, which fits standard slots. If you plan to use it with a CPU cooler, ensure the heatsink frame can accommodate the 25mm depth. Regular maintenance involves dusting the white frame and blades. Dust accumulation can reduce the 47.6 CFM airflow and increase noise levels. Clean the silicone feet periodically to maintain vibration damping. This fan suits users who prioritize white aesthetics and quiet operation. It complements other case fans by providing reverse airflow for directed cooling. You should pair it with high-static pressure fans if pushing air through dense filters. The 4-pin PWM connector allows automatic speed adjustments based on system temperature.
Check before you buy
- Confirm motherboard has 5V ARGB header for lighting control.
- Check case supports 120mm mounting holes and 25mm depth.
- Ensure PWM header is available for automatic speed control.
- Plan for fewer than six fans in series to prevent signal loss.
