However, the included speed controller accepts a universal AC input of 100V–240V (50\/60Hz), converting it to DC 3V–12V — making it compatible with standard wall outlets in the US, EU, and most countries worldwide.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can I control the fan speed?\u003c\/h4\u003e\n\u003cp\u003eA: Yes! The included speed control adapter allows you to adjust the output voltage from DC 3V to DC 12V, giving you full control over the fan's rotational speed. Lower voltage = quieter, slower fan; higher voltage = maximum 3000RPM airflow performance.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What chassis or systems is this fan compatible with?\u003c\/h4\u003e\n\u003cp\u003eA: This fan uses the standard 120x120x25mm form factor, which is compatible with most PC chassis, server cabinets, workstations, BTC\/cryptocurrency mining rigs, and network equipment enclosures that accept 120mm fans. The DC 5.5x2.1mm connector ensures broad device compatibility.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How long will this fan last?\u003c\/h4\u003e\n\u003cp\u003eA: This fan is rated for 40,000–50,000 hours of operational life, thanks to its high-quality Dual Ball or Hydraulic bearing construction. That equates to roughly 4–5+ years of continuous 24\/7 operation.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What voltage does this 120mm cooling fan operate on?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"The fan itself is rated for DC 12V.
