GAMDIAS NOTUS M1-1201 120mm Black PWM Case Fan (400–1600 RPM, 57.56 CFM, 25 dBA, Hydraulic Bearing)
Technical specification
The GAMDIAS NOTUS M1-1201 is a premium all-black 120 mm PWM performance fan engineered for high airflow with whisper-quiet operation. Designed with a closed-loop control system, optimized tip clearance and a high-quality hydraulic bearing, it delivers up to 57.56 CFM airflow within a 400–1600 RPM range while keeping noise down to around 25 dBA even at maximum speed. Built from durable PBT material with anti-vibration rubber pads, the NOTUS M1-1201 is ideal for demanding cooling applications in cases, air coolers and liquid coolers.

- Superior airflow performance: Dynamic 400–1600 RPM PWM range with airflow up to 57.56 CFM provides strong cooling for cases, radiators and heatsinks. [web:2729][web:2728][web:2724]
- Whisper-quiet operation: Optimized blade design, 1 mm tip clearance and hydraulic bearing keep noise as low as ~25 dBA even at full speed. [web:2729][web:2728][web:2724][web:2737]
- Closed-loop RPM control: Steady RPM technology maintains consistent fan speed and airflow for stable cooling performance. [web:2729][web:2724][web:2738]
- Durable hydraulic bearing: High-quality hydraulic bearing reduces friction for longer lifespan and smoother rotation. [web:2729][web:2724][web:2739]
- Anti-vibration pads & PBT frame: Anti-vibration rubber pads covering most of each corner and a PBT frame minimize vibration and resonance. [web:2729][web:2726][web:2739]
