Square 13.5 cm case fan black frame oil bearing 2-pin connector

SXDOOL

SXDOOL RL4Z 13.5 cm 12 V 0.33 A case fan

SKU CH-PG5E-JAJ2H MPN RL4Z

13.5 cm case fan running at 1700 RPM on 12 V with 0.33 A draw and oil-seal bearing

  • 12 V 0.33 A power draw keeps energy use low
  • 1700 RPM reference speed moves air through the chassis
  • Oil-seal bearing reduces friction for quieter operation
  • 135 × 135 × 25 mm frame fits standard 120 mm mounting holes
  • Small 2-pin connector plugs straight into compatible headers

13.5 cm 12 V chassis fan

The SXDOOL RL4Z is a 135 mm square frame fan rated for 12 V and 0.33 A. It targets builders who need a direct replacement for 135 mm mounting patterns in chassis or power supply cooling roles. The oil-seal bearing supports a reference speed of 1700 RPM for steady airflow in standard cooling configurations. Buyers who need PWM speed control or larger diameter fans should look elsewhere.

Mounting constraints and interface

The frame uses parallel hole spacing of 120 mm and diagonal spacing of 171 mm, so it only fits cut-outs and brackets designed for that 135 mm footprint. A small 2-pin power connector supplies the 12 V feed without speed reporting or variable control. Other interface options are not detailed in the specifications, limiting integration to basic two-wire headers.

Build quality and daily implications

The 25 mm thick frame houses an oil-seal bearing that reduces friction for consistent rotation at the rated speed. The compact 135*135*25 mm profile allows installation in tight power supply or chassis cavities where larger fans cannot mount. The fixed two-pin connection means the fan runs at full voltage whenever powered, so system builders must plan for constant airflow or external fan controllers.

Questions about this item

Should I choose the 135 mm square frame with 120 mm parallel hole spacing or the 171 mm diagonal spacing for my case?

The fan has a single 135 mm square frame drilled for both 120 mm parallel and 171 mm diagonal mounting patterns, so it fits either standard.

What does the 1700 RPM speed reference mean for airflow and noise inside a real chassis?

At 1700 RPM the 13.5 cm blade moves a moderate volume of air; expect audible but not loud airflow suitable for general chassis or power-supply cooling.

How does the small 2-pin interface limit speed control on a modern motherboard?

The 2-pin connector supplies fixed 12 V power only, so the fan runs at full 1700 RPM constantly with no PWM or voltage regulation from the board.
