## Long description

The Alphacool ES Guardian 4Port Powerfan Hub is a power and monitoring adapter for high-consumption server and industrial fans that cannot be powered directly from standard mainboard headers. It connects to the power supply and provides four 4-pin PWM fan outputs, enabling fan speed monitoring and control via the mainboard. The hub is designed for in-case mounting and includes provisions for additional power if individual fans draw more than 1.5 A (18 W).
Advantages
The Powerfan Hub supplies sufficient current to up to four high-power fans while providing a single 4-pin PWM interface to the mainboard for speed control and monitoring. Individual monitoring can be enabled or disabled using the integrated 4-way DIP switch. A separate power input is available to support fans that exceed the per-channel current limit. Visual status LEDs on the fan connectors and an audible alert option increase fault visibility.
Suitable for
Server and rack systems with high-power industrial fans
Workstations or industrial PCs where mainboard fan headers cannot supply required current
Situations requiring centralised fan monitoring and RPM reporting to the mainboard
Environments needing audible or visible fan-failure alerts
Key specifications
Connector type: four 4-pin PWM fan outputs
Monitoring: RPM signal forwarded from first active monitored fan to mainboard
Per-fan current support: up to 1.5 A (18 W) per fan without additional power connector; extra power connector provided for higher draw
Control: 4-way DIP switch for individual monitoring enable/disable
Additional interfaces: speaker port for piezo buzzer or PC speaker; status LEDs on fan connectors
Mounting: in-case mounting with M3x4 mm screws and M3x6 mm spacers (mounting hardware referenced in manual)
How to use
Mount the ES Guardian 4Port Powerfan Hub inside the case using the supplied M3 screws and spacers. Connect the hub to the PSU using the included power cable; if any fan requires more than 1.5 A (18 W), attach the additional power connector to the PSU. Plug up to four 4-pin PWM fans into the fan outputs and connect the hub's 4-pin PWM cable to the mainboard fan header. Configure the 4-way DIP switch to enable or disable monitoring for individual fan channels. After connection, the mainboard can read RPM values and control fan speeds via the single PWM interface.
Usage recommendations
Use the additional power connector whenever a connected fan’s current draw exceeds 1.5 A to avoid overloading the hub or PSU rail. Verify mainboard compatibility with shared PWM/RPM signalling if RPM reporting or fault alerts are required. For audible alerts, connect a compatible piezo buzzer or PC speaker to the speaker port.
