Ventoinha de caixa Jonsbo HF2-120 Reverse Blade PWM ARGB 120mm Preto, controlo PWM, iluminação ARGB

Jonsbo HF2-120 is a 120mm reverse-blade case fan that combines directed airflow and addressable RGB illumination with PWM speed control. Designed for installation in standard 120mm chassis mounts, this fan can be used as intake or exhaust to support CPU, GPU and general system cooling while adding synchronized ARGB lighting to modern gaming and workstation builds.

Advantages

The reverse-blade design improves airflow characteristics in confined chassis spaces while reducing turbulence compared with conventional blade profiles. PWM control allows automatic fan speed adjustment based on motherboard or controller signals to balance cooling performance and noise. Addressable RGB lighting delivers individually controllable illumination patterns when connected to compatible ARGB headers or controllers, enabling coordinated effects across multiple components. The fan’s 120mm form factor and standard mounting make it compatible with most PC cases and fan brackets.

Suitable for

• Case intake or exhaust in desktop PCs
• Cooling front, top or rear chassis fan mounts
• Systems requiring synchronized ARGB lighting
• Gaming rigs and workstation builds with limited internal space

Key specifications

• Size: 120 mm diameter
• Blade type: reverse-blade profile for directed airflow
• Control: PWM speed control compatible with standard 4-pin fan headers
• Lighting: addressable RGB (ARGB) with compatible 3-pin 5V headers
• Frame color: black
• Mounting: 4-screw standard 120mm pattern

How to use

Install the Jonsbo HF2-120 into any standard 120mm fan mount using the four mounting points. Connect the 4-pin PWM cable to a motherboard fan header or PWM hub to enable automatic speed control. For lighting, connect the ARGB cable to a compatible 3-pin 5V ARGB header or controller and configure lighting effects through the motherboard or external controller software. Place the fan as intake or exhaust according to desired airflow direction and system thermal layout, ensuring unobstructed airflow paths and cable routing to avoid contact with the blades.

Recommendations

Use PWM fan curves in BIOS or software to balance acoustic and thermal performance; set higher speeds under load for better cooling and lower speeds at idle to reduce noise. When using ARGB, verify header voltage and pinout compatibility before connecting, and group multiple ARGB devices on compatible controllers to maintain stable power and synchronized effects.
