SKU CH-R5Z2-F0DKK MPN EF50201S1-C000-F99

A 50 mm by 20 mm maglev turbine blower running on 12 V DC at 1.02 W with three wires for CPU, IC, power or Optoma T761ST projector cooling

  • Maglev bearing reduces friction for quieter operation
  • 12 V DC power keeps wiring simple in standard builds
  • 02 W draw limits heat added to the chassis
  • 50 mm by 20 mm frame fits tight projector and IC slots
  • Three-wire connection enables speed monitoring and control

Compact turbine blower for tight builds

The SXDOOL EF50201S1-C000-F99 is a 50 mm by 20 mm DC12V turbine blower rated at 1.02 W. Its maglev bearing and three-wire lead suit precision cooling in small-form-factor PCs, industrial boards or the Optoma T761ST projector.

Maglev bearing and three-wire control

Maglev suspension reduces mechanical wear and keeps acoustic output low during continuous operation. The 12 V three-wire connector delivers power and a tachometer signal so the host can monitor speed without extra circuitry.

Direct drop-in for 50 mm turbine slots

This unit replaces an identical 50 mm maglev turbine when the original fails or runs loud. The jump is worth it only when the existing slot matches the 50 mm by 20 mm footprint and the 12 V three-wire header. Builders needing larger airflow or a different mounting pattern should look elsewhere.

Questions about this item

What connector does the 3-wire 12 V fan use and what does it limit?

The 3-wire lead carries 12 V power, ground and a tachometer signal; it reports speed but cannot accept PWM control, so the fan runs at full voltage unless the motherboard varies the 12 V rail.

Will the 50 mm by 20 mm blower fit my projector or CPU cooler bracket?

The housing measures 50 mm square and 20 mm thick with a centre-mounted turbine outlet; verify that your Optoma T761ST or cooler has the matching screw pattern and clearance before ordering.

How do I install the maglev turbine blower and what step is often missed?

Mount the fan with the four corner screws, connect the 3-wire plug to a 12 V header, then confirm in BIOS or monitoring software that the tachometer signal registers — skipping this check leaves a silent failure undetected.
