12025 Brushless DC Cooling Fan — 4.75 Inch (120×120×25mm) 12V Exhaust Fan

Description

12025 Brushless DC Cooling Fan — 4.75 Inch (120×120×25mm), 12V

Deliver powerful, reliable airflow to your system with the 12025 Brushless 12V DC Exhaust Cooling Fan. Built to the standard 120mm × 120mm × 25mm (4.75 inch) form factor, this fan is engineered for consistent forced-air cooling across PC builds, server enclosures, industrial control panels, and ventilation systems — anywhere that demands dependable thermal management.

The brushless motor eliminates the mechanical wear associated with brushed designs, delivering a rated service life exceeding 30,000 hours. Operating at 12V DC — the standard voltage on ATX PSU rails, industrial power supplies, and 12V adapters — this fan is a straightforward, drop-in cooling upgrade with no additional circuitry required.

Key Features

• Brushless motor — extended lifespan, reduced noise, zero brush maintenance
• Standard 120mm mounting — fits all 120mm fan mounts with M4 corner screws
• 12V DC input — compatible with ATX PSUs, 12V rails, and industrial power supplies
• 25mm slim profile — maximises airflow within tight chassis clearances
• Axial exhaust design — optimised for exhaust and intake applications
• Low vibration frame — quiet operation suitable for always-on installations

Installation Guide

1. Identify airflow direction — the label side faces the air intake; the frame/strut side is the exhaust.
2. Connect the red wire to 12V positive and the black wire to GND. If using a 3-pin connector, the yellow wire carries tachometer signal for speed monitoring.
3. For PC builds: plug the connector into a chassis fan header on your motherboard or directly into a Molex adapter on the PSU.
4. Secure with four M4 screws through the corner mounting holes into your panel, bracket, or chassis.
5. Ensure a minimum 15mm clearance on both the intake and exhaust sides for unrestricted airflow.
6. Keep fan blades and grilles free of dust build-up — clean with compressed air every 3–6 months for optimal performance.

The 12025 Brushless 12V DC Fan ships ready to install — standard 120mm mounting, no adapters needed. Compatible with virtually every 120mm fan slot across consumer and industrial enclosures.
