SXD HA1425M12SB-Z 140×25 mm 12 V 0.36 A 2236 RPM 68 CFM 29 dBA case fan

SKU CH-B5DN-QKZ4M MPN HA1425M12SB-Z

A 140 mm PWM case fan delivering 68 CFM at 2236 RPM with a 29 dBA noise level

  • PWM control enables precise speed adjustment via four-wire connection
  • 68 CFM airflow delivers strong cooling for server chassis
  • 29 dBA operation keeps acoustic output low under load
  • 140 × 25 mm frame fits standard large-fan mounting points
  • 12 V 0.36 A draw balances performance with modest power use

140 mm PWM case fan for servers

This 140 mm fan runs on 12 V and draws 0.36 A through a four-wire PWM connection. It spins at 2236 RPM to deliver 68 CFM of airflow at a rated 29 dBA. The 25 mm thick frame fits standard 140 mm mounting points in server and workstation chassis. It is built for continuous operation in rack environments.

Four-wire PWM control

The PWM lead lets the motherboard or fan controller vary speed automatically based on temperature sensors. This reduces acoustic output when thermal load is low while still providing full 68 CFM when demanded. No separate fan controller or voltage adapter is required for speed regulation.

12 V PWM interface limits

Speed range and minimum RPM are defined by the PWM implementation on the host board, not by the fan alone. The 0.36 A current draw must be supported by the fan header or splitter used. Builders needing higher static pressure or lower noise at equivalent airflow should evaluate alternative models.

Fragen zu diesem Artikel

How often should I clean the 140 mm blades to keep the 2236 RPM speed stable?

Dust the blades and frame every few months with compressed air; buildup reduces airflow below the rated 68 CFM and forces the motor to run hotter.

Which limit appears first when the fan runs at full 2236 RPM for hours?

The 29 dBA noise floor becomes noticeable before thermal limits; the 0.36 A draw stays within the 12 V header rating during continuous operation.

What noise and heat should I expect from the 12 V 0.36 A motor during all-day use?

Expect a steady 29 dBA hum and warm — not hot — frame temperature; the four-wire PWM connection lets the motherboard lower speed when full 68 CFM isn’t needed.
