Cooling fan BitsPower Notos RGB PWM 120mm white, 3-pack

BitsPower Notos RGB PWM 120mm white 3-pack are case cooling fans designed for desktop PC systems. Each fan combines a 120mm airflow frame with addressable RGB illumination and PWM speed control to balance cooling performance and acoustic levels. The set of three fans is intended for installation in chassis intake, exhaust or radiator positions to support CPU, GPU and general component cooling while adding uniform white housing and RGB lighting to the build.

Advantages

The fans provide adjustable speed through PWM control for precise airflow management and quieter operation at low loads. Addressable RGB lighting enables customizable color effects when connected to a compatible RGB controller or motherboard header, giving visual coherence across the system. The white frame improves contrast and light diffusion for RGB effects, and the 120mm size fits common mounting locations in most modern PC cases.

Suitable for

• Case intake and exhaust cooling in mid-tower and full-tower PC cases
• Mounting on 120mm radiators for AIO liquid-cooling solutions
• Improving airflow for CPU and GPU heat dissipation
• Custom builds where RGB lighting and white color accents are desired

Key specifications

• Fan size: 120 mm
• Control: PWM speed control compatible with motherboard fan headers
• Lighting: Addressable RGB LEDs (requires compatible RGB controller/header)
• Frame color: White
• Pack quantity: 3 fans

How to use

Install each 120mm fan into appropriate case locations using the standard four mounting points. Connect the fan power and tachometer cable to a PWM-compatible 4-pin fan header on the motherboard or to a PWM fan controller to enable automatic speed regulation. Connect the RGB cable to a compatible addressable RGB header or controller to manage lighting effects; follow your motherboard or controller manual for proper pin orientation and software configuration. Ensure fan airflow direction aligns with your case cooling plan (intake or exhaust) and secure cables to avoid contact with the blades.

Recommendations

For balanced cooling and noise, configure PWM curves in BIOS or software to increase fan speed under higher CPU/GPU load and reduce speed at idle. When using the fans on radiators, allow a small gap between fan frame and radiator fins to reduce vibration transfer. Use compatible RGB control software or a hardware controller to synchronize lighting across multiple fans and other RGB components.
