With an incredibly slim 4mm profile, it easily slips into tight 3D-printed enclosures, compact VR headsets, or densely packed custom PCBs to prevent microchips from thermal throttling. Its straightforward 2-wire design means you can power it directly from any standard 5V DC source without worrying about complex PWM signal wiring.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 class=\"ng-star-inserted\"\u003e\u003cspan class=\"ng-star-inserted\"\u003eLightweight and Fire-Retardant Build\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp class=\"ng-star-inserted\"\u003e\u003cspan class=\"ng-star-inserted\"\u003eWeighing only 2 grams, this\u003cspan\u003e \u003c\/span\u003e\u003c\/span\u003e\u003cstrong class=\"ng-star-inserted\"\u003e\u003cspan class=\"ng-star-inserted\"\u003eMicro Cooling Fan\u003c\/span\u003e\u003c\/strong\u003e\u003cspan class=\"ng-star-inserted\"\u003e\u003cspan\u003e \u003c\/span\u003eutilizes a UL 94V-0 rated PBT thermoplastic frame and impeller for maximum safety and minimal weight. This makes it an exceptional choice for weight-sensitive applications like Tiny Whoop RC drones or portable wearable devices, ensuring your project remains light while adhering to strict fire safety standards. The internal sleeve bearing provides smooth, low-noise operation suitable for quiet indoor environments.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 class=\"ng-star-inserted\"\u003e\u003cspan class=\"ng-star-inserted\"\u003ePro Tip from Our Technicians\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp class=\"ng-star-inserted\"\u003e\u003cspan class=\"ng-star-inserted\"\u003eTo ensure a long lifespan for the sleeve bearing, our Sham Shui Po technical team strongly advises mounting this fan in a vertical orientation rather than horizontally. Sleeve bearings retain their internal lubrication much better when mounted vertically, preventing premature wear and noise. Furthermore, while this fan is rated for 5V, it can also operate at 3.3V with reduced airflow, making it highly versatile for direct connection to 3.3V microcontroller pins.\u003c\/span\u003e\u003c\/p\u003e","brand":"Sun Cheong Computer Company Limited","offers":[{"title":"Default Title","offer_id":48093873701015,"sku":"21FN000284","price":148.0,"currency_code":"TWD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0440\/4022\/4919\/files\/ultra-thin-4mm-cooling-fan-side-profile.jpg?v=1785664931","url":"https:\/\/scccltd.com\/en-tw\/products\/18x18x4mm-5v-dc-micro-brushless-fan","provider":"Sun Cheong Computer Company Limited","version":"1.0","type":"link"}
