Slim 120 mm case fan for tight builds

The Silverstone AS120B is a 120 mm case fan with a 15.6 mm slim profile designed for space-limited systems. Its nine scimitar blades generate high static pressure for rapid heat dissipation through radiators or heatsinks. An all-copper fluid dynamic bearing reduces friction for long operational life.

Builders with slim chassis or radiator clearance

This fan suits compact cases and slim radiators where a standard thicker fan cannot be installed. It also works well as an exhaust fan moving large volumes of heat out of the system. Buyers who need a thicker fan with different mounting dimensions should consider other options.

15.6 mm thickness decides fit

The defining specification is the 15.6 mm thickness which determines whether the fan fits your chassis or radiator clearance. Verify the available space in your build before purchasing. The UPC 844761022181 confirms the exact model.

Questions about this item

How quiet is the 15.6 mm slim fan when running continuously?

The all-copper Fluid Dynamic Bearing reduces friction, keeping noise low even during extended operation.

What connector does the AS120B need on my motherboard or controller?

The fan uses a standard 3-pin or 4-pin PWM header for power and speed control.

Will the 120 mm Air Slimmer fit alongside my older full-size case fans?

Its 15.6 mm thickness leaves extra clearance, so it installs beside thicker fans without blocking adjacent slots.
