135mm dual-ball-bearing case fan

The SXDOOL DFB13512H is a 135mm square chassis fan built around a dual ball bearing for longer service life. It runs on 12 V DC, draws 0.28 A and spins at 1800 RPM with a 10 % tolerance. The two-wire connector supplies power without speed reporting or PWM control.

Two-wire power connector

The red and black lead pair delivers simple voltage control through any 2-pin header or adapter. No tachometer signal or PWM input is present, so fan speed cannot be monitored or regulated by the motherboard. Builders who want software-controlled curves or RPM feedback need a three- or four-wire alternative.

120mm mounting holes and 29 dBA noise

Mounting holes are spaced at 120 mm, matching many 120mm fan patterns and some PSU shrouds. At 29 dBA the airflow is audible but not intrusive in a typical case. The 25 mm thickness and 135 mm frame limit use to locations that accept this specific footprint.

Questions about this item

How long do the dual ball bearings last before they need replacement?

Dual ball bearings typically outlast sleeve bearings and can run for years at 1800 RPM without scheduled replacement.

What limits continuous operation at 1800 RPM?

The 0.28 A current draw and 29 dBA noise level are the main constraints during sustained use.

How much heat and noise does the fan produce when running all day?

It runs at 1800 RPM, draws 0.28 A at 12 V and emits 29 dBA, so heat output is low and noise stays moderate.
