It connects to any ATX power supply with a standard 4-pin Molex output connector.\u003c\/p\u003e\n\u003ch4\u003eQ: Why is oxygen-free copper used in this fan splitter cable?\u003c\/h4\u003e\n\u003cp\u003eA: Oxygen-free copper provides lower electrical resistance compared to standard copper, resulting in more efficient and stable power delivery to all connected fans — important when running multiple fans simultaneously from a single Molex rail.\u003c\/p\u003e\n\u003ch4\u003eQ: Is this fan adapter suitable for cryptocurrency mining rigs?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. Mining rigs often require multiple fans for adequate airflow across GPUs and components. This 4-way splitter lets you power four fans from one Molex connector, simplifying cable management and reducing the number of PSU connections needed.\u003c\/p\u003e\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What does this 4-Pin Molex fan splitter adapter do?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"This 4-Pin Molex fan splitter adapter takes a single 4-pin Molex power connector from your PSU and splits it into four fan headers, allowing you to run up to four 3-pin or 4-pin cooling fans simultaneously — great for PC cases, CPU cooling towers, and mining rig builds.\"}}, {\"@type\": \"Question\", \"name\": \"What type of fans is this Molex fan adapter compatible with?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"This adapter is compatible with standard 3-pin and 4-pin PC fans, including case fans, CPU cooler fans, and chassis fans.
