VGA Cooler PWM Fan Adapter Gelid CA-PWM-02 for GPU Cooling Fan PWM Control

Gelid CA-PWM-02 is a PWM fan adapter created to add pulse-width modulation control to VGA cooler fans. The adapter lets a graphics card fan accept a PWM signal from a motherboard or dedicated PWM controller so fan speed can be adjusted automatically in response to temperature or controller settings. It is compact and intended for use in GPU cooling upgrades, fan replacements and custom cooling configurations where PWM control is preferred over fixed-voltage operation.

Advantages

The adapter enables precise speed control of a VGA cooler fan using standard PWM signals without the need to modify the fan or motherboard. It preserves the original fan connector form factor while providing compatibility with PWM-capable headers, supporting quieter operation and improved thermal regulation. Installation is straightforward, offering a practical solution for retrofitting non-PWM GPU fans or integrating additional cooling into a PC system.

Suitable for

• Upgrading GPU cooling to add PWM-based speed control
• Replacing or repairing VGA cooler fans that lack native PWM control
• Custom PC cooling setups where centralized PWM control is required
• Testing and tuning fan curves for graphics card temperature management

Key specifications

• Function: PWM fan adapter for VGA cooler fans to receive PWM control
• Compatibility: Designed for typical VGA cooler fan headers and PWM-capable controller or motherboard headers
• Control method: Pulse-width modulation (PWM) signal pass-through or conversion to enable dynamic fan speed regulation
• Form factor: Compact inline adapter for minimal space impact inside PC chassis
• Use case: Intended for GPU cooling applications, fan upgrades and repairs

How to use

Connect the adapter between the VGA cooler fan cable and a PWM-capable header on the motherboard or a PWM controller. Ensure connectors are aligned correctly and seated firmly. After connection, configure the motherboard or controller fan profile to use PWM control so fan speed adjusts automatically according to temperature or the selected fan curve. Verify proper operation by monitoring fan response to system load and temperatures.

Usage recommendations

Use the adapter only with compatible VGA cooler fans and PWM-capable headers. Confirm connector pinouts before installation to avoid incorrect wiring. For optimal cooling and noise balance, set a fan curve in the motherboard or controller software and test under different loads. If unusual noise or lack of speed control occurs, recheck connections and compatibility, and consult fan/controller documentation.
