Slim 15mm 120mm case fan

The Silverstone FN123 is a 120mm case fan with a 15mm slim profile designed for compact chassis. It spins at 2000 rpm and delivers 32.6CFM of airflow while producing 23.5dBA of noise. A long-life sleeve bearing and three-pin power connector complete the specification.

Builders fitting space-constrained cases

This fan suits builders who need a thin 15mm unit for small-form-factor or low-clearance enclosures. The white blades and black frame match neutral colour schemes. Buyers who require PWM speed control or higher static pressure for dense radiators should look elsewhere.

Three-pin fixed-speed connector

The FN123 uses a three-pin connector, so fan speed is regulated by voltage rather than PWM. Systems that only provide four-pin headers can still run the fan, but automatic duty-cycle control will not be available.

Questions about this item

How often will the long life sleeve bearing need replacement?

The long life sleeve bearing is designed for extended service and has no specified replacement interval under normal case cooling use.

Will the 2000 rpm speed limit airflow or noise first during continuous operation?

At 2000 rpm the fan delivers 32.6 CFM while producing 23.5 dBA, so neither airflow nor noise hits a hard limit before the other under sustained load.

What is the noise and heat output when the fan runs all day at 2000 rpm?

Continuous operation at 2000 rpm generates 23.5 dBA of noise; the motor draws minimal power through the 3-pin connector and adds negligible heat to the case.
