Also important to note that UL Listed products are tested while UL Recognized products are not tested. Both levels require a direct marking on the part which means this fan has neither level. To be honest most fans at this price level are not going to be agency tested just because the target market is PC case fans, and the things UL tests for are not relevant to PC builders. The fan has CE certification which is just saying it won't burn your house down. CE doesn't check fans for performance; you're better off reading reviews than looking for agency approvals if this is a PC fan. **Q: will this fan work with just pos & neg hooked up? do I need all for wires hooked up to work ? thanks** A: Will work with just pos and neg. **Q: If I plan to use more than 50% capacity of the 5300rpm model, would I need to connect it to a controller/hub rated for more than 1amp per lane?** A: I would make sure that which ever Fan Port you connect this High Airflow Fan that it will support the amperage stated in the specs of the fan. **Q: Any water or dust resistance rating? ip52, ip67?** A: I do not see any water/dust proof rating printed, however, I use this fan as a range-top exhaust fan in suction mode, so all cooking steam & grease-laden fumes are drawn across/through the fan... daily. Thus far, it has performed flawlessly, despite the harsh environment. I recommend this fan. ## Frequently Bought Together - Wathai 12038 120mm x 38mm PWM Computer PC Case Fan 12V 4pin 5300rpm 230 CFM High Airflow Duall Ball CFM FG DC Brushless Cooling Fan - Taidacent 2510-4P 3P Manual 4 Wires 0-5V 12V Fan Speed Controller PWM Speed Control On Off Switch for PC CPU Case Fan with Knob (Solder Connector with Plastic Black Knob) - Noctua NF-F12 iPPC 3000 PWM, Heavy Duty Cooling Fan, 4-Pin, 3000 RPM (120mm, Black) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hk/products/139075285-4-72inch-4pin](https://www.desertcart.hk/products/139075285-4-72inch-4pin) --- *Product available on Desertcart Hong Kong* *Store origin: HK* *Last updated: 2026-08-14*
