The input is a 4-Pin connector, and it splits into three 3-Pin fan outputs, making it compatible with the vast majority of ATX, Micro-ATX, and Mini-ITX boards.\u003c\/p\u003e\n\u003ch4\u003eQ: Can I run three fans at full speed using this splitter cable?\u003c\/h4\u003e\n\u003cp\u003eA: The splitter shares the power from a single motherboard fan header across three fans. It is recommended to use fans with a combined current draw within your motherboard fan header's rated output (typically 1A). For best results, use lower-draw fans or check your motherboard manual for the maximum header amperage before connecting multiple fans.\u003c\/p\u003e\n\u003ch4\u003eQ: Does this cable support PWM fan speed control on all three outputs?\u003c\/h4\u003e\n\u003cp\u003eA: The input side is a 4-Pin PWM connector; however, the three output connectors are 3-Pin. This means fan speed control via PWM signal is not passed to the output fans — the fans will run based on voltage control. The cable is ideal for ensuring all three fans receive stable power from one header.\u003c\/p\u003e\n\u003ch4\u003eQ: How long is the cable and will it reach fans at the top or front of my case?\u003c\/h4\u003e\n\u003cp\u003eA: The cable measures 27–30 cm (approximately 10.6–11.8 inches) in length. This is sufficient for most mid-tower case fan placements near the motherboard fan header, though very large full-tower cases may require additional cable management or extension.\u003c\/p\u003e\n\u003c!-- production-packaging-notice --\u003e\n\u003ch3\u003eProduction \u0026amp; Packaging Notice\u003c\/h3\u003e\n\u003cp\u003eTo maintain high stock availability and fast shipping times, our items are sourced from multiple verified manufacturing facilities.
