This is a Y-cable that connects three 4-pin PWM fans to one 4-pin PWM connector. Fan control via the mainboard with PWM fans is by far more affordable than a fan controller, so this cable is ideal for increasing flexibility. This is a Y-cable that connects three 4-pin PWM fans to one 4-pin PWM connector. The extension cable is covered with black mesh, which protects the cable. This sleeving provides a long cable life. The connector end is secured with heat shrink tubing for a clean finish. The white marking on one of the Y-cable cables indicates the cable through which the RPM signal is sent. Sleeving: This cable is not only practical but also visually appealing. The mesh surrounding the cable itself provides the benefits that all promodders are looking for. You will be amazed by the combination of cable connectors, sleeving, and heat shrink tubing used to achieve a superior design and a unique and elegant appearance.
