Overview

The Thermaltake Pure A12 LED White (CL-F109-PL12WT-A) is a 120mm case fan designed for builders who want to add clean, consistent lighting to their system without the cost and complexity of full RGB. Its nine white LEDs are distributed across the fan blades to produce uniform brightness and strong color saturation, giving your case a polished, cohesive look. The fan fits standard 120mm mounting points, making it suitable for front, rear, or top case positions as well as radiator use.

Built with a hydraulic bearing, the Pure A12 aims to balance quiet operation with adequate airflow for general cooling duties. It connects via a 3-pin header, so speed is managed through voltage regulation rather than PWM — a trade-off that keeps the design simple but limits fine-tuned control. For users building a themed rig on a budget, or anyone who prefers a single clean color over the complexity of addressable RGB, the Pure A12 LED White is a practical and visually appealing choice.

Key Features

The hydraulic bearing self-lubricates with a high-quality, friction-reducing substance, which lowers operation noise while improving thermal efficiency. The seal cap prevents lubricant leakage and extends the lifespan of the unit.

Pure A12 fan not only creates an aesthetically pleasing liquid cooled system but also delivers extraordinary performance during operation. The fans are available in four colors to match with any build you desire
