In the PC cooling market, magnetic fans have gained popularity in recent years due to their ease of installation and reduced cable clutter. They allow for cleaner case interiors and simpler system management. Building on this trend, manufacturers are now moving toward all-in-one fan solutions that combine simplified installation with enhanced aesthetics.
JONSBO has introduced into this segment with the ZB-120B, ZB-360B, and ZB-360BR full-width infinity mirror case fans, available in multiple sizes to support different cooling setups. The fans feature a one-cable connection system for both fan and ARGB lighting control, reducing wiring complexity. Installation is handled through four mounting points, while the design incorporates lighting around the hub and frame, along with infinity mirror effects on all four sides. This approach provides a uniform lighting style across the entire fan assembly.
While the ZB-360B and ZB-360BR share the same physical dimensions of 362 × 123 × 28 mm, their specifications differ. The ZB-360B runs at 700–2400 RPM, with airflow rated at 20.95–65.26 CFM, static pressure between 0.45–3.20 mmH₂O, and noise levels ranging from 20.3–36.6 dB(A). The ZB-360BR operates at a lower speed range of 700–1800 RPM, delivering 18.75–47.71 CFM of airflow, static pressure of 0.33–1.66 mmH₂O, and reduced noise levels at 16.4–30.7 dB(A).
Both models are powered via a PWM 4-pin connector for fan control and a 3-pin ARGB connector for lighting. Rated service life is listed at 20,000 hours at 25 °C, with the ZB-360B consuming up to 6.60 W for the fan and the ZB-360BR drawing 4.20 W. Each requires 6.75 W for the LED system.
This review will take a closer look at installation, performance, acoustics, and lighting of the JONSBO ZB-120B, ZB-360B, and ZB-360BR to evaluate how they perform in practical use.

Unboxing
The JONSBO ZB-120B, ZB-360B, and BR Fans come in a plain black box that highlights the brand name, model number, and product image on the front. Turning to the back, the packaging provides the key specifications, along with variant options and details of available colors. The series is offered in both black and white, giving users flexibility when pairing the cooler with their build.
Unboxing the cooler shows a simple yet organized layout. The main unit is secured in a molded plastic insert to prevent movement during shipping, while a protective paper cover with the text “For Your Real Needs” sits on top. Removing the paper reveals the fans placed inside. The box also includes four long and four short fan screws, covering the basic installation requirements.
Closer Look
The JONSBO ZB-120B, ZB-360B, and ZB-360BR series are designed with durability and consistency in mind. The fans are built from solid plastic materials that provide a sturdy feel, while the smooth edges and even finishing reflect careful manufacturing. Each model carries a clean appearance that suits modern PC cases, and the availability of a White edition offers an option for systems with lighter themes, giving builders more flexibility when planning their setup.
Visually, the series combines seven translucent blades with a mirrored center hub to create the Infinity effect, a design that has become common in today’s cooling Fans. Around the frame, a full ARGB light guide ring delivers even illumination, helping to maintain a uniform glow across the fan surface. Together, these features bring consistent lighting that integrates easily into different system configurations, whether the goal is to maximize cooling efficiency or complement a build with a strong visual theme.
The rear of the fans carries the JONSBO logo on the central cap. The ZB120B is equipped with four rubber pads located around the screw holes, while the ZB-360B and ZB-360BR use eight pads placed at the sides and in the middle of the mounting points. These pads help reduce vibration transfer and limit resonant noise when installed inside a case.
The Fans uses a full-frame infinite mirror design with lighting on all four sides, delivering an even glow across the panel. Its extended lighting area ensures consistent coverage, enhancing the overall visual effect. Out of the box, the mirror surface is protected by high-transmittance stickers that help prevent scratches during handling and installation. This approach maintains both the look and condition of the mirror finish until it is ready for use.
The JONSBO ZB-120B, ZB-360B, and ZB-360BR cooling fans are built with standard connectors for both power and lighting. They use a 4-pin PWM interface, which allows the motherboard or a controller to regulate fan speeds for balanced performance and noise levels. The fans support serial connection, so multiple units can be linked together to reduce cable clutter inside the case. For lighting, a 3-pin ARGB connector is used, also with a serial design, making it easier to synchronize effects across several fans without requiring extra adapters.
Features
The ZB-120B is a 120 mm fan with speeds up to 2400 RPM, delivering airflow of 20.95–65.26 CFM and static pressure up to 3.20 mmH2O. Noise levels range from 20.3–36.6 dB(A), while power usage is rated at 2.40 W for the motor and 3.55 W for the lighting. The ZB-360B follows the same performance profile but in a triple-fan layout for 360 mm radiators, drawing higher power per fan while maintaining the same 20,000-hour durability rating.
The ZB-360BR is a reverse airflow version, operating at 700–1800 RPM with airflow of 18.75–47.71 CFM and static pressure up to 1.66 mmH2O. Its lower noise output of 16.4–30.7 dB(A) makes it the quietest in the series, while still providing reliable cooling for larger cases and radiators. Power consumption is 4.20 W for the fan and 6.75 W for the LEDs, with the same long-term lifespan as the standard models.
ARGB Lighting Effects
The ARGB fans deliver consistent and well-balanced illumination across the system. Each blade is evenly lit, producing smooth color transitions and accurate reproduction without visible hotspots. Lighting is also present on the side, adding an extra layer of depth to the overall design.
Compatibility with leading motherboard software allows the effects to synchronize with other ARGB hardware for a unified look. Users can choose from multiple modes, such as static, breathing, or wave patterns, or adjust custom profiles to suit their setup. With fans mounted on the front and top panels, the lighting creates a uniform glow that highlights the components while maintaining a cohesive appearance inside the case.
Testing and Performance
The JONSBO ZB-120B, ZB-360B, and ZB-360BR were installed together in one system to evaluate their combined cooling capability. The test build featured an Intel Core Ultra 7 265K processor on a Maxsun iCraft Z890 Arctic motherboard, paired with an RTX 4080 SUPER MASTER graphics card. Testing was carried out at stock settings in a room temperature of 28 °C.
During AIDA64 stress testing, the Core Ultra 7 265K maintained an average temperature of 71 °C, with maximum peaks reaching 75 °C. The radiator mounted at the top, supported by the fan configuration, kept the processor stable under extended load. Boost frequencies were sustained throughout the test period, and no thermal throttling occurred.
The RTX 4080 SUPER MASTER was stressed separately using FurMark. Under full load, the GPU stabilized at 67 °C, assisted by the bottom intake fans directing airflow toward the card. Clock speeds remained consistent during the test, confirming steady thermal control.
To replicate a gaming scenario, Cyberpunk 2077 was played at 4K resolution with ray tracing enabled. CPU temperatures ranged from 60–65 °C, while the GPU recorded 64–66 °C during extended gameplay. The system operated without instability or performance drops across several hours of testing.
Acoustic measurements were taken 50 cm from the front panel. At idle, the system measured 33 dBA. Under combined CPU and GPU stress, the reading increased to 42 dBA. The mix of higher-speed and reverse-airflow fans allowed for balanced cooling across the chassis while keeping overall noise within acceptable limits.
