Product Review
This adapter cable allows your to connect standard fan header devices to your graphics card. Most graphics cards use a proprietary mini 4-pin connector for their fans but the electrical connection is identical to traditional 4-pin PWM enabled fans. This cable is especially ideal for use in graphics cards modified with an AIO cooler where the nearby fan and pump can connect directly to the graphics card. One important thing to highlight is that not all connections in a fan splitter can be split. Pin 3 (RPM tachometer) is the signal that is generated by the fan (or pump) and sent back to the fan header for software RPM monitoring. This signal cannot be split to multiple fans as it would cause inaccurate RPM reading. Please take note which can connector has the 3rd pin as it will be the primary device sending the RPM signal back to your graphics card.
