The product is a 120x120x32mm 12V DC centrifugal blower fan with an IP44 rating, suitable for use in inflatable and DIY cooling applications. It features a 2-pin power connection and a maximum fan speed of 3000 RPM, offering efficient cooling performance. The black plastic fan is compatible with a universal range of brands and comes with a 1-year manufacturer warranty, ensuring reliability and quality. Ideal for improving airflow in computer cases or other cooling applications, this blower fan provides a powerful and effective cooling solution.

• MEASURE BEFORE YOU BUY: 120 x 120 x 32 mm (4.72 x 4.72 x 1.26 in) — a square centrifugal blower, NOT a small axial fan. Compare your original unit's frame size, mounting holes and air outlet direction before ordering; inflatable bases and enclosures vary.
• IP44 MOISTURE-PROOF, NOT WATERPROOF: splash-resistant for dry indoor and damp environments; do not submerge or expose to rain.
• 2-PIN XH2.54 CONNECTOR, 520mm LEAD: red wire = positive (+), black = negative (−). If your device uses bare wire, a DC barrel jack or a different 2-pin plug, splice or swap the connector before wiring. Reversed polarity means the motor will not spin.
• POWER REQUIREMENT: 12V DC, 1.2A (14.4W) , 3000RPM, 31.62CFM, 60dBA. Use a 12V supply rated at least 1.5–2A. A USB port, amplifier remote wire or weak 12V source will NOT drive it reliably.Full-speed noise ~60dBA (similar to a pedestal fan) — not silent. Runs 5–12V with an external voltage controller for airflow tuning (controller NOT included).
• NOT A UNIVERSAL DROP-IN FAN: mounting holes, outlet direction and connector differ across inflatables, amplifiers and enclosures. Verify fit before replacing; you may need to adapt the mount or splice the lead. Suited for 12V inflatable blower replacement, amp / AV rack, refrigerator, router and DIY cooling.
