UF3H3-710 Ultra-Thin 5V Cooling Fan 17x17x3mm | High-Speed

UF3H3-710 Ultra-Thin 5V/3.3V Cooling Fan — 17×17×3mm

Need serious airflow in a seriously tiny package? The UF3H3-710 ultra-thin cooling fan delivers impressive large-volume airflow from a remarkably compact 17×17×3mm form factor. Whether you're building a custom DIY electronics project, cooling a Raspberry Pi, or managing heat in a slim embedded device, this micro fan punches well above its size.

Key Features

• Ultra-Compact Design: Only 17mm × 17mm × 3mm — fits in the tightest enclosures and PCB layouts where standard fans simply won't.
• Wide Voltage Range: Operates on DC 3V–5V, making it compatible with 3.3V and 5V power rails straight from a microcontroller, USB port, or single-cell Li-ion circuit.
• High-Speed Rotation: Spins at 18,000–30,000 RPM for powerful, consistent airflow despite its miniature size.
• Low Power Consumption: Draws just 80mA at 5V (0.4W total) — efficient enough for battery-powered and USB-powered builds.
• USB-Compatible Voltage: Rated at DC 5V, ideal for powering directly from a USB 5V supply or development board output pin.
• Reliable Construction: Engineered for steady continuous operation in embedded systems, DIY electronics, and compact computing builds.

Frequently Asked Questions

Q: What voltage does the UF3H3-710 ultra-thin cooling fan support?

A: The fan operates across a DC 3V–5V voltage range, with a rated voltage of DC 5V. This makes it fully compatible with standard 3.3V microcontroller GPIO outputs and 5V USB power supplies, giving you flexibility across most DIY and embedded electronics builds.

Q: How small is this mini cooling fan and where can it be used?

A: The fan measures just 17mm × 17mm × 3mm — roughly the size of a large coin. Its ultra-thin profile makes it ideal for use in tight enclosures such as Raspberry Pi cases, slim embedded systems, IoT device housings, 3D printers, and any custom electronics project where space is at a premium.

Q: How fast does the UF3H3-710 fan spin and how much airflow does it produce?

A: Despite its compact size, this fan reaches speeds of 18,000–30,000 RPM, generating surprisingly large airflow relative to its dimensions. This high-speed rotation ensures effective heat dissipation for small but heat-sensitive electronic components.

Q: Is the UF3H3-710 cooling fan compatible with USB power?

A: Yes. The fan's 5V rated voltage is directly compatible with standard USB 5V power output. You can power it from a USB port, USB hub, or any 5V USB charger by connecting appropriately to its leads — no additional voltage regulation is needed at 5V.
