120mmx2 ARGB PWM Case Fans, Jonsbo ZA-240 Infinity Mirror 240mm Black

The Jonsbo ZA-240 Infinity Mirror 240mm black fan assembly combines two 120mm PWM fans with addressable RGB lighting and a mirrored diffuser to create a continuous infinity effect. Designed for case or radiator mounting, this dual-fan unit delivers regulated airflow and customizable lighting for desktop PC cooling setups. The PWM control enables automatic speed adjustments based on system temperature, while the ARGB interface provides synchronized illumination when connected to compatible controllers or motherboards.

Advantages

The dual 120mm PWM fans provide balanced airflow and quiet operation through automatic speed regulation. The infinity mirror ARGB diffuser offers a distinctive, deep lighting effect that can be synchronized with system lighting ecosystems. The assembly format simplifies installation in 240mm radiator mounts or case fan slots and reduces cable clutter compared with separate fan installs.

Key specifications

• Fan size: two 120 mm fans in a 240 mm assembly
• Control: PWM speed control for automatic RPM regulation
• Lighting: addressable RGB with infinity mirror diffuser
• Mounting: compatible with 240 mm radiator mounts and standard 240 mm case fan positions
• Color: black housing and frame

How to use

Install the fan assembly into a 240 mm radiator or case mounting position using the included screws. Connect the PWM power cable to a motherboard fan header or fan controller capable of PWM control to allow automatic speed adjustments. Connect the ARGB cable to a compatible addressable RGB header or controller to enable lighting control and synchronization. Ensure cables are routed to avoid contact with the fan blades and verify airflow orientation before finalizing installation.

Recommendations

For optimal cooling performance, use the ZA-240 as either intake or exhaust in a balanced airflow configuration and enable PWM control in BIOS or fan software. When pairing with an AIO radiator, mount the fans to match the radiator’s airflow direction. If lighting synchronization is desired, connect to a motherboard ARGB header and configure effects through the motherboard utility; if no ARGB header is available, use a compatible external controller.
