AABCOOLING Black Silent Fan 9

Quiet 92 mm fan with FDB bearing

AABCOOLING Black Silent Fan 9 is a quiet and efficient 92 mm computer fan. It runs at a constant speed of 1700 rpm (±10%) and delivers an airflow of 76 m³/h at a noise level of just 21 dB(A).

Smooth, quiet operation is ensured by the oil-filled FDB (Fluid Dynamic Bearing), with a service life of up to 100,000 hours – much longer than sleeve bearings. Mounting screws and silicone anti-vibration washers are included.

Key features

• Quiet operation – 21 dB(A)
• Efficient airflow – 76 m³/h
• Oil-filled FDB bearing – 100,000 h service life
• Cable in black sleeving, 3-pin connector
• Solid construction
• Mounting screws and silicone anti-vibration washers included

Advantages of the FDB bearing

• no friction between bearing parts – longer service life,
• the oil dampens vibrations,
• noise is generated practically only by the fan blades,
• protection against oil leakage,
• spiral oil filling ensures even lubrication of the entire bearing,
• a solution also used in hard drives.

Applications

Case cooling works by expelling warm air. The power supply fan alone often cannot provide good cooling, despite running at high speed and making a lot of noise. AABCOOLING Black Silent Fan 9 can be used as:

• a computer case fan – with two fans, one at the front and one at the rear of the case, you get very good airflow,
• a fan on a CPU heatsink (size 92 × 92 × 25 mm),
• a quiet replacement for a noisy power supply fan.

Mounting and connection

The fan is fixed with four screws, just like standard fans in cases and power supplies (hole spacing 82 × 82 mm). This makes replacing a noisy fan with a quieter one quick and easy.

Ways to connect the fan when mounted in a power supply:

• connect the fan to a 3-pin header on the motherboard and route the cable (30 cm) into the power supply through a gap – the fan speed can then be read in the BIOS,
• take apart the 3-pin plug and connect the fan directly inside the power supply: the black wire is ground, the red is plus (+) and the yellow carries the speed signal (if it is not connected, the BIOS cannot read the speed). Taking the plug apart voids the right to return the product.
