Fan controller Aqua-Computer 53283 — 4-pin connector, rated current 4.5 A, 57×39×16 mm

Aqua-Computer 53283 is a compact fan controller for desktop PC cooling systems. The unit provides a single 4-pin connector for PWM-capable fans, supports a rated current of 4.5 A and measures 57 × 39 × 16 mm. The controller is supplied as a single module intended to manage fan speed via PWM or to supply regulated power to an individual cooling fan, offering a small footprint for tight installation spaces.

Advantages

The controller is compact and suitable for installations where space is limited. Its 4-pin connector enables PWM-based speed control while the 4.5 A rated current supports higher-load fans within its specification. The small dimensions make mounting straightforward behind panels or inside crowded cases. The design focuses on reliable, regulated fan supply and simple integration into existing cooling setups.

Suitable for

• Controlling a single PWM-capable chassis or CPU fan
• Replacing a single fan power regulator in compact builds
• Applications requiring a low-profile fan controller inside a desktop case

Key specifications

• Connector type: 4-pin PWM fan connector
• Rated current: 4.5 A
• Dimensions: 57 × 39 × 16 mm
• Single-unit module for individual fan control

How to use

Connect the 4-pin connector to a PWM-capable fan header on the motherboard or fan controller, ensuring correct orientation of the connector. Verify that the motherboard header supports PWM control. After connection, configure fan curves or PWM duty cycle in BIOS or a compatible motherboard/fan control software to manage fan speed. Ensure the fan's current draw does not exceed the controller's 4.5 A rating. Place the controller in a location with adequate ventilation and secure it using available mounting points or adhesive options in the case.

Recommendations

Use the Aqua-Computer 53283 with PWM-capable fans and check the fan's current specification before installation. Avoid connecting multiple high-current fans to this single-output controller; if multiple fans or signal amplification are needed, consider a dedicated splitter or active distribution solution. Ensure secure mounting and avoid obstructing airflow around the controller and connected fan.
