AABCOOLING Silent Force Fan 12

Quiet 120 mm fan with FDB bearing

AABCOOLING Silent Force Fan 12 is a 12 cm fan from the Force series featuring as many as 11 specially profiled blades. They increase performance by approx. 50% compared with standard fans while keeping noise to a minimum.

The motor with a modern IC controller ensures stable operation, and the quiet, oil-filled FDB (Fluid Dynamic Bearing) provides a service life of up to 100,000 h – much longer than sleeve bearings. The fan runs at a constant 1100 rpm (±10%), delivers an airflow of 97 m³/h and generates only 12.9 dB(A).

Key features

• Dimensions 120 x 120 x 25 mm
• 11 specially profiled blades
• Modern IC motor
• Quiet FDB bearing, 100,000 h service life

Applications

The fan improves PC cooling by exhausting warm air from the case – something the power supply fan alone often cannot do, even at high speed and with considerable noise. You can install it:

• on a 120 mm CPU cooler heatsink – as a quiet replacement for a noisy fan,
• in a PC case – at the front, rear or on the side panel,
• in an ATX computer power supply.

FDB bearing

• no friction and extended service life,
• vibrations damped by oil,
• noise generated only by the fan blades,
• protection against oil leakage,
• spiral oil distribution for even lubrication of the entire bearing,
• technology also used in hard drives.

Ordinary sleeve bearings rub against each other during operation and heat up, which significantly shortens their service life.

Installation and connection

The fan is fastened with four screws, just like standard fans in cases and power supplies, so replacing a noisy fan is quick and easy. In a power supply you can connect it in two ways:

1. To the motherboard – route the 30 cm cable into the power supply through any gap. You can then read the current fan speed in the BIOS.
2. Directly in the power supply – after disassembling the 3-pin plug: the black wire is ground (–), the red wire is power (+) and the yellow wire transmits the speed signal. Without the yellow wire connected, the BIOS cannot read the fan speed.

Note: disassembling or cutting off the plug excludes the possibility of returning the fan.
