AABCOOLING Super Silent Fan 25 is a quiet fan measuring 218 x 218 x 30 mm, featuring 13 dynamically shaped blades. It runs at 800 rpm ±10%. Airflow is 232 m³/h and the noise level is 14.9 dB. The modern FDB (Fluid Dynamic Bearing) ensures smooth, quiet operation and a lifespan of 100,000 h.

Key features

• Solid construction – 218 x 218 x 30 mm
• Modern IC motor
• Cable in black sleeving
• Quiet FDB bearing
• Airflow 232 m³/h
• Mounting screws and anti-vibration pads included
• Lifespan 100,000 h

Applications

Due to its non-standard size, installing it in a PC requires custom adaptation of the case or side panel. The fan is also suitable for a caravan, for example, to improve air circulation, as well as for small rooms and devices that need extra ventilation.

FDB bearing – quiet and durable

• No friction and a longer lifespan – ordinary sleeve bearings rub and heat up, which shortens their life.
• Vibrations are damped by the oil.
• Practically the only source of noise is the fan blades.
• Protection against oil leakage.
• Spiral oil distribution ensures even lubrication – the oil does not collect in one part of the bearing.
• The same bearing technology is used in hard drives.

Installation and connection

The fan is fixed with four screws in holes spaced 170 x 170 mm apart.

• Direct connection (e.g. inside a power supply) after removing the 3-pin plug: the black wire is ground (–), the red wire is power (+) and the yellow wire carries the speed signal. Without the yellow wire, the BIOS cannot read the speed. A product with a removed plug cannot be returned.
