Dual-fan ARGB unit

The JONSBO ZB-240B integrates two 120mm ARGB fans into a single 240mm by 28mm frame that mounts in standard case locations. It targets builders who want co-ordinated lighting and airflow without managing separate fan headers or cables.

PWM and 5V ARGB limits

Speed is regulated by a 4-pin PWM signal across a 700-2400rpm range, delivering 20.95-65.26 CFM at 0.45-3.20 mmH2O with noise between 20.3-36.6 dB(A). The 5V ARGB interface requires a compatible motherboard header or controller that can address 52 circumference LEDs plus 18 axis LEDs per unit.

Unified frame and daisy-chain wiring

A one-piece frame removes the gap between fans and uses a joint structure for straightforward screw mounting. One combined cable carries both PWM and ARGB signals to the motherboard, while male and female 5V ARGB connectors allow daisy-chaining to other lighting devices.

Questions about this item

Should I pick the 240 mm 28 mm version or a thinner 120 mm fan for my case?

The ZB-240B is a single 242 mm long frame holding two 120 mm fans at 28 mm thickness, so it fits 240 mm radiator mounts and delivers 20.95-65.26 CFM without needing separate fan headers.

What does the 2400 RPM top speed actually give me inside a build?

At 2400 RPM the pair pushes up to 65.26 CFM and 3.20 mmH2O static pressure while staying at 36.6 dB(A), making it strong enough for radiator or high-restriction mesh panels.

How does the 4-pin PWM and 3-pin 5V ARGB connector limit what I can control?

The 4-pin PWM header lets the motherboard regulate 700-2400 RPM speed automatically, while the 3-pin 5V ARGB link (with male and female ends) chains lighting to other 5V ARGB devices for unified effects.
