The Thermalright TL-C12015 is a 120mm slimline fan designed for CPU cooling or case ventilation, featuring a thickness of only 15mm to fit in compact builds. It operates at a maximum speed of 1500 RPM with 4-pin PWM control, allowing automatic speed adjustment based on system temperature. The fan frame is constructed from durable engineering-grade plastic with reinforced corners to reduce vibration, and the seven-blade impeller is engineered for balanced airflow and static pressure. Surface treatment on the blades minimizes turbulence, contributing to quieter operation. The included 4-pin connector supports motherboards with PWM headers, ensuring precise fan curve customization through BIOS or software. The motor is a long-life sleeve bearing design, rated for extended continuous use under standard conditions. At a price point of $10.62, this model offers an accessible entry into reliable cooling without compromising essential features. The compact 15mm profile makes it suitable for HTPC, ITX, or slim chassis where standard 25mm fans cannot fit.

Additionally, the fan can be used as a replacement for stock coolers or as an auxiliary exhaust fan in space-constrained scenarios. The PWM range typically spans from around 600 RPM to 1500 RPM, providing a good balance between noise and cooling performance at low loads. The fan blades are injection-molded from a high-quality polymer that maintains shape integrity over time. The frame includes anti-vibration pads on the mounting corners to further reduce rattling. The product is packaged with standard mounting screws and a PWM splitter cable for multi-fan setups.

The TL-C12015 is a functional and affordable cooling component that prioritizes slim form factor and quiet operation.
