Graphics Card Fan Splitter GENNEL 4-Pin to Dual 4-Pin 100mm Cable

Description

Product Overview

The GENNEL Graphics Card Fan Splitter is engineered to provide a reliable bridge between a single 4‑pin PWM header on a graphics card and two separate 4‑pin fan connectors. Constructed from high‑temperature resistant PVC jacket and gold‑plated contacts, the cable maintains signal integrity even under heavy load. The 100mm (4″) length is deliberately short to minimize airflow obstruction while offering enough slack for easy routing within compact chassis. Each connector is clearly labeled: Connector A accepts the GPU 4‑pin female plug, while Connector B splits into two male 4‑pin plugs, one of which carries a three‑wire PWM‑only line for precise speed regulation.

Designed with both hobbyist and professional builders in mind, this splitter supports full PWM functionality, allowing each fan to be independently controlled by the GPU’s fan curve. The cable’s robust construction resists abrasion, heat, and chemical exposure, ensuring a long service life even in over‑clocked or high‑performance systems. Compatibility spans a wide range of modern graphics cards, from entry‑level models to high‑end GPUs that demand multiple cooling fans for optimal thermal performance.

Usage

Installation is straightforward: power down the system, locate the 4‑pin PWM header on the graphics card, and plug the female connector of the splitter into the header. Then connect your two GPU fans to the male connectors, ensuring the PWM wire aligns correctly for the fan that requires speed control. This setup is ideal for builds where space is at a premium, such as mini‑ITX or small‑form‑factor cases, because the short cable reduces clutter and improves airflow pathways.

The splitter excels in scenarios where additional cooling is required without adding extra headers. For example, high‑performance gaming rigs, workstation PCs running intensive compute tasks, or cryptocurrency mining rigs can benefit from the ability to attach multiple fans to a single header, keeping GPU temperatures low and maintaining system stability. The PWM support ensures that each fan can ramp up or down based on the GPU’s thermal demands, providing silent operation during low‑load periods and aggressive cooling when needed.

FAQ

Can I use this splitter with any GPU fan?

Yes, the splitter is compatible with any standard 4‑pin PWM GPU fan. Ensure the fan’s connector matches the 4‑pin layout, and the PWM wire aligns correctly for speed control.

Will using a splitter affect fan performance?

No. The splitter maintains full PWM functionality, allowing each fan to respond to the GPU’s fan curve independently. Performance is comparable to using separate headers.

Is the cable length sufficient for larger cases?

The 100mm length is optimized for most builds, especially compact cases. For larger chassis, the short length helps keep the interior tidy, but you can route the cable along the case interior to reach fans positioned farther away.

What warranty does GENNEL provide?

GENNEL offers a 12‑month limited warranty covering manufacturing defects. Our support team is available to assist with any issues you may encounter.

Do I need any tools to install the splitter?

No special tools are required. Simply plug the female connector into the GPU’s 4‑pin header and attach your fans to the male connectors. Ensure the system is powered off before installation.
