Black 140mm square case fan with hydraulic bearing and 3-pin connector

SXDOOL

SXDOOL RL4Z 140mm case fan 1200RPM 3-pin

SKU CH-R3PG-1CETC MPN RL4Z

A 140 mm hydraulic-bearing case fan spinning at 1200 RPM with a 3-pin connector for quiet, high-volume airflow

  • TypeCase Fan
  • Fan Size140mm
  • Bearing TypeHydraulic
  • RPM<1600 RPM
  • Power Connector3 Pin
  • ColorBlack
  • Quiet operation with high airflow at 1200 RPM
  • 140 mm hydraulic-bearing fan for long service life
  • 3-pin 12 V connector fits standard motherboard headers
  • Compact 140 × 140 × 25 mm frame suits tight builds
  • 30 cm cable allows flexible routing inside the case

Built for EVGA PSU Replacement

This 140 mm hydraulic-bearing fan matches the RL4Z specification used in select EVGA power supplies. It runs at 1200 RPM with a 12 V, 0.30 A draw and a 30 cm three-pin lead. The non-LED black frame keeps the look neutral inside any chassis.

Hydraulic Bearing and Three-Pin Control

The hydraulic bearing targets long service life while keeping noise low at high airflow. A three-pin connector plugs directly into a motherboard or fan hub, giving voltage-based speed control without PWM. The 140 mm by 25 mm frame fits standard mounting holes for straightforward installation.

Drop-In Fit with Short Lead

The 30 cm cable reaches most PSU or case headers without extensions. No extra screws, adapters or software are bundled, so the package contains only the fan itself. Builders needing PWM control or longer cables will need separate accessories.

Questions about this item

What does the 3-pin connector limit for speed control on this 140mm fan?

The 3-pin connector supplies 12 V DC and allows voltage-based speed control only; PWM duty-cycle control is not supported.

What clearance and screw spacing does the 140 mm × 25 mm frame require?

The fan needs a 140 mm square mounting hole pattern and 25 mm depth clearance inside the case or PSU shroud.

How is the fan wired into a motherboard header, and which wire is often misidentified?

Plug the 3-pin connector onto a 12 V motherboard fan header; the yellow wire is the tachometer signal, not a PWM input.
