Overview

The Thermaltake Pure Duo 12 ARGB Sync is a 120mm case and radiator fan built around two independent rings of addressable LEDs. These dual rings sit on opposite sides of the fan frame, producing even illumination that syncs directly with 5V ARGB-capable motherboards from ASUS, MSI, Gigabyte, and ASRock. The result is smooth, customizable lighting without the need for a standalone controller or proprietary software — just connect the included 5V RGB header cable and manage effects through your motherboard's lighting suite.

On the cooling side, a hydraulic bearing keeps the fan running quietly with a maximum noise output of 28 dB-A, while PWM control allows the motherboard to modulate speed between 500 and 1500 RPM depending on system temperatures. At full tilt, the fan pushes up to 56.51 CFM of airflow with 1.72 mm-H₂O of static pressure, making it suitable for case ventilation and standard radiator duty. The compact 120 x 120 x 25 mm form factor and 168-gram weight ensure compatibility with virtually any ATX or micro-ATX chassis, and the 40,000-hour bearing lifespan means years of reliable operation before replacement is needed.

Pros & Cons

👍 Pros

  • Dual independent ARGB rings produce uniform, vivid lighting across the entire fan face.
  • PWM speed range of 500–1500 RPM allows the motherboard to balance noise and airflow automatically.
  • Hydraulic bearing rated at 40,000 hours provides long service life with low friction.
  • Noise level stays at a reasonable 28 dB-A maximum even at full speed.
  • Standard 5V RGB header means no extra controller box is needed for motherboard sync.

👎 Cons

  • Static pressure of 1.72 mm-H₂O is modest, which may limit performance on thick or dense radiators.
  • Requires a 5V addressable RGB header — systems with only 12V RGB headers will need an adapter.
  • Maximum airflow of 56.51 CFM is adequate but not class-leading among 120mm fans.
  • No included RGB controller means users without a compatible motherboard header cannot control lighting out of the box.

Frequently Asked Questions

The Pure Duo 12 ARGB is designed for 5V addressable RGB headers on compatible motherboards. It syncs with motherboard RGB software such as ASUS Aura Sync, MSI Mystic Light, and Gigabyte RGB Fusion — no proprietary controller is required.
It uses a standard 4-pin (2510-4P) PWM connector, allowing your motherboard to automatically adjust fan speed between 500 and 1500 RPM based on temperature.
It is rated as a radiator fan with 1.72 mm-H₂O static pressure, so it works well mounted on liquid cooling radiators as well as in standard case fan positions.
Thermaltake rates the hydraulic bearing at 40,000 hours at 25°C, which translates to roughly 4.5 years of continuous operation.
This specific SKU (CL-F115-PL12SW-B) includes fans in a pack — check the listing quantity, as Thermaltake offers both single and dual-pack versions under similar model numbers.
