DeepCool SC790 Fan Controller

DeepCool SC790 | PWM & ARGB Fan Hub Controller

The DeepCool SC790 Fan controller delivers centralised control for up to six PWM ARGB fans, synchronising lighting and speed through a single compact hub. Designed for builders who want cleaner cable routing and reduced motherboard header load, it connects directly to a 3-pin 5V ARGB header and 4-pin PWM header while drawing stable power via SATA.

Centralised PWM & ARGB Control

By linking to both the ARGB and PWM headers, the SC790 enables simultaneous fan speed and lighting control across all six connected devices. This eliminates the need for multiple splitters and keeps all adjustments in one software interface, making system tuning faster and more consistent.

Magnetic Mounting for Flexible Installation

The hub’s magnetic back panel allows it to attach securely to any ferrous surface, such as the inside of a case’s motherboard tray. This keeps the unit out of sight while maintaining easy access for cable management, helping preserve a clean build aesthetic.

Stable Power Delivery via SATA

Powering all six fans through the motherboard headers can risk voltage drops or instability. The SC790’s dedicated SATA power input ensures each fan receives consistent 12 V and RGB LEDs get stable 5 V, preventing performance issues during heavy loads or full lighting effects.

Compact Design with Minimal Footprint

Measuring just 60 mm wide and 17 mm deep, the hub occupies minimal space inside the chassis. Its low profile means it can be tucked behind panels or mounted out of the airflow path without interfering with other components.

Frequently Asked Questions

Q: Does the SC790 require software to function?

A: No, basic speed and lighting control works through the motherboard’s ARGB and PWM headers. Advanced features may need compatible motherboard software.

Q: Can I use non-ARGB fans with this hub?

A: The hub can power standard 3-pin/4-pin fans for PWM control, but ARGB lighting will not function without ARGB-compatible fans.

Q: Is the SATA power cable included?

A: Yes, the unit ships with a SATA power connector for stable device power.

Q: How many fans can be controlled simultaneously?

A: Up to six PWM ARGB fans can be connected and synchronised at once.
