This thermalright tl c12015w s CPU fan review examines a slim 120mm cooler designed for tight spaces. It measures just 15mm in depth, making it ideal for low-profile builds or radiator mounts where clearance is limited. The unit features a maximum speed of 1500 RPM and delivers 52 CFM of airflow. It uses a 4-pin PWM connector for motherboard speed control and includes 5V 3-pin ARGB lighting. This fan balances quiet operation with adequate cooling performance for standard air coolers or small radiators.
What stands out
- 15mm slim profile fits tight cases and low-profile coolers
- 1500 RPM max speed with 52 CFM airflow
- ≤24.1 dBA noise level for quiet operation
- 5V 3-pin ARGB with 17 lighting modes
- 1.24 mm H2O static pressure for radiator use
Who it fits
Good fit for
You should choose this fan if you need a low-profile solution for a small form factor case or a compact CPU air cooler. The 15mm depth allows it to fit where standard 25mm fans will not. The 4-pin PWM interface lets your motherboard manage speeds based on temperature. The ARGB lighting is a bonus for users who want synchronized lighting effects without needing a separate hub. It is also suitable for pushing air through thin radiators due to its static pressure rating.
Who should skip it
Skip this model if you require high static pressure for thick, dense radiators. The 1.24 mm H2O rating is modest compared to high-performance fans designed for heavy airflow resistance. You should also avoid it if you need 12V ARGB lighting, as this unit only supports 5V 3-pin protocols. If you prioritize absolute silence above all else, note that the max speed reaches 1500 RPM, which may be audible under load. Users needing RGB rather than addressable RGB will find this incompatible.
Verdict: The Thermalright TL-C12015W-S is a practical choice for slim builds and low-profile CPU coolers. Its combination of low depth and ARGB lighting makes it a solid spec-based option for compact systems.
Key specs explained for this fan
Fan Size: 120mm
This measurement describes the width and height of the fan frame. A 120mm size is the standard for most PC cases and radiators. You can easily find mounting points for this fan in your case. It fits where larger 140mm fans might not, giving you more flexibility for compact builds or specific radiator thicknesses.
Max Fan Speed: 1500RPM
This is the maximum rotational speed of the fan blades. At this speed, the fan moves more air to cool your CPU. The PWM control allows the motherboard to adjust this speed based on temperature. You get quiet operation at low loads and higher performance when your system is under heavy stress.
Max Airflow: 52CFM
CFM measures the volume of air the fan moves per minute. A rating of 52CFM indicates strong airflow for its slim profile. This helps push heat away from your CPU cooler or out of your case. You benefit from efficient heat dissipation, which keeps your components running at safer temperatures during intensive tasks.
Noise Level: ≤24.1dBA
This value indicates the maximum sound pressure level in decibels. A limit of 24.1dBA is considered very quiet for a computer fan. You will hear minimal noise from this unit during normal operation. This makes it suitable for quiet PC builds where acoustic comfort is a priority, even when the fan is running at higher speeds.
Static Pressure: 1.24mm H2O
Static pressure measures the fan's ability to push air through resistance. This value indicates how well the fan performs against obstacles like dust filters or dense radiator fins. A rating of 1.24mm H2O is decent for a slim fan. It ensures adequate airflow when mounted on radiators or in tight spaces with restricted air paths.
Lighting Type: 5V 3-pin ARGB
This specifies the connector and voltage for the addressable RGB lighting. A 5V 3-pin connection is standard for modern motherboards. It allows you to sync the fan colors with other compatible components. You can create a unified lighting theme across your build using your motherboard's software without needing separate controllers.
Slim Build and ARGB Finish
According to the listing, this fan measures 120 by 120 by 15 millimeters. The 15mm depth classifies it as a slimline model. This thin profile allows installation in tight spaces where standard fans will not fit. You can mount it on radiators or inside cases with limited vertical clearance. The unit weighs 3.53 ounces, keeping the load on your mounting points low.
The frame uses a white finish to match modern aesthetic themes. The blades feature high-brightness LED atomizing technology. This design reflects light to create a softer ARGB effect. You can control up to 17 lighting modes through a 5V 3-pin ARGB connector. This allows synchronization with compatible motherboards for unified visual themes across your build.
Vibration damping pads surround the fan frame. These pads reduce friction noise during rotation. The listing states this results in quieter operation. You connect the fan to the motherboard using a 4-pin PWM cable. This interface enables automatic speed control based on system temperature. The fan adjusts its 1500 RPM maximum speed to balance cooling performance and noise levels. This layout makes it suitable for both case ventilation and CPU cooler mounting.
Setup And Daily Use Guide
Installing this fan requires connecting two separate cables to your motherboard. The first is a 4-pin PWM connector for power and speed control. This interface allows your system to automatically adjust the fan speed based on temperature readings. The listing states the maximum speed reaches 1500 RPM. You can use this setting for balanced cooling performance. The second connection is a 5V 3-pin ARGB cable. This port synchronizes the lighting effects with compatible motherboard software. You can choose from up to 17 different light modes. The atomized blades help diffuse the light for a softer appearance. This dual-connector setup ensures the fan operates efficiently while providing visual customization. In daily use, the 120mm size fits standard mounting points in most cases and radiators. The 15mm slim profile makes it suitable for tight spaces or low-profile builds. The included vibration damping pads reduce friction noise during operation. The listing specifies a maximum noise level of 24.1 dBA. This quiet operation helps maintain a peaceful environment. The fan delivers 52 CFM of airflow and 1.24 mm H2O of static pressure. These specs support effective heat removal from CPUs or case components. You can mount it as a case fan or alongside a CPU cooler. This flexibility allows you to create a comprehensive cooling solution. The 4-pin PWM control ensures the fan runs only as fast as needed. This approach helps conserve energy and extend the fan's lifespan. The slim design also aids in cable management within compact builds.
Before You Buy This Fan
This fan requires two separate connections on your motherboard. You must plug in the 4-pin PWM cable for speed control and the 5V 3-pin ARGB cable for lighting. Check your motherboard headers for both types before purchasing. The 15mm slim profile fits most standard 120mm mounts, but verify your case or radiator thickness. Ensure you have enough rear I/O headers for the lighting sync. Keep the fan blades clean to maintain airflow. Dust buildup can reduce the 52CFM rating over time. This unit suits users who need quiet operation under 24.1dBA. It complements other Thermalright options in this guide by offering a low-profile solution. If you need higher static pressure for dense radiators, consider the non-slim variants. This model prioritizes thinness and aesthetic sync. It is a practical choice for compact builds where space is limited. The vibration damping pads help reduce noise during operation. Ensure your case has adequate depth for the fan frame.
Check before you buy
- Verify motherboard has 5V 3-pin ARGB header
- Confirm case supports 120mm slim fan mounts
- Check radiator thickness for 15mm clearance
- Ensure sufficient PWM fan headers are available
