The Thermalright 5 Pack TL-C12C-S is a set of five 120mm ARGB case cooler fans designed for efficient airflow and silent operation in desktop computer systems. Each fan features a 4-pin PWM connector, allowing the motherboard to dynamically adjust fan speed from 0 to 1550 RPM, balancing cooling performance with noise levels. The fan blades are constructed from durable, reinforced engineering plastic, and the frame is built with rigid materials to minimize vibration and maintain structural integrity over long-term use. At the core of each fan is a S-FDB (Shell-Fluid Dynamic Bearing) that reduces friction and wear, contributing to extended service life and consistent, low-noise rotation.

The ARGB lighting is integrated into the fan hub and supports a wide range of motherboard lighting control software, enabling customizable color patterns and synchronization with other addressable RGB components. The fan delivers up to 66.17 CFM of airflow at maximum speed, with a static pressure of 1.53 mmH₂O, making it suitable for both intake and exhaust configurations in mid-tower and full-tower cases. The package includes five individually sleeved, 4-pin PWM extension cables, along with all necessary mounting screws and anti-vibration pads that reduce noise transfer to the chassis.

The S-FDB bearing technology ensures smooth rotation even under sustained load, and the fan’s electrical design includes over-current protection for added reliability. The ARGB controller is not required, as the fans can be daisy-chained via standard ARGB headers on modern motherboards. These fans are compatible with a wide range of CPU coolers and case mounting points, supporting both pull and push configurations.

The 120mm form factor and standard 25mm thickness allow easy installation in most ATX, micro-ATX, and mini-ITX cases. The black, low-profile design with translucent fan blades offers a clean aesthetic that fits into both professional and gaming builds. The PWM control range ensures silent operation at low loads, while the maximum speed provides ample cooling during demanding tasks.

In terms of value, this five-pack offers a cost-effective solution for upgrading multiple case fans without sacrificing build quality or performance. The inclusion of ARGB lighting and PWM features at a modest price point makes it a practical choice for builders seeking a balanced combination of airflow, noise control, and visual customization. The durable construction and tested bearing system contribute to long-term reliability in typical desktop environments.
