Ventoinha Jonsbo CR-3000 ARGB 12 cm 600-1500 rpm 22-32 dB preto

The Jonsbo CR-3000 ARGB is a 120 mm case fan designed for PC cooling applications. It operates at an adjustable speed range of 600–1500 RPM and delivers a maximum airflow of 59.48 CFM while maintaining a low acoustic profile between 22 dB and 32 dB. The fan uses a hydraulic bearing for extended lifespan and stable operation, and includes addressable RGB lighting for system customization. Its black frame and blade design suit a variety of desktop builds where efficient airflow and quiet operation are required.

Advantages

The fan combines variable-speed operation with a wide airflow capability to balance cooling performance and noise levels. Hydraulic bearing technology reduces friction and wear, improving reliability and service life under continuous use. Addressable RGB lighting adds visual customization without compromising airflow, and the 120 mm form factor is compatible with most standard case and radiator mountings.

Suitable for

• Case ventilation for desktop PCs
• Supplementary airflow for CPU or GPU cooling
• Mounting on radiators in compact or mid-tower systems
• Builds requiring low-noise operation with adjustable fan speed

How to use

Install the fan in a compatible 120 mm mounting location inside the PC case or on a compatible radiator, aligning the airflow direction as required for intake or exhaust. Connect the power and tachometer cable to the motherboard or fan controller that supports the fan's voltage and PWM or DC control method. Connect the addressable RGB header to a compatible ARGB controller or motherboard header and configure lighting through the system software or a dedicated controller. Verify secure mounting with screws and confirm the fan spins freely before powering the system for extended operation.

Recommendations

For optimal balance of cooling and low noise, set the fan speed to a mid-range value during normal desktop use and increase speed under heavier loads or during gaming sessions. Periodically clean dust from the blades and frame to maintain airflow and check mounting screws for firmness. Use a motherboard header or fan controller that supports adjustable control to fully utilize the fan's speed range and monitor rpm through system software if available.
