Fans 4710NL-05W-B59 12025 24V case fan

SKU CH-P7W3-8YTQR MPN 4710NL-05W-B59

A 120 mm square, 25 mm thick case fan with double-ball bearings and a 24 V three-wire speed-sense interface rated for 180,000 hours MTBF

  • Double-ball bearing with IC extends lifespan to 180,000 hours MTTF
  • 24V 0.31A three-wire design enables precise speed monitoring
  • 120mm x 25mm frame fits standard server and industrial chassis
  • NMB-MAT Silent IC series reduces acoustic noise in sensitive environments
  • Built for medical, rail and new-energy vehicle cooling applications

Industrial-grade 12025 24V case fan

This 120 * 120 * 25mm axial fan runs on 24V at 0.31A and uses a double ball bearing with a specialised IC for speed measurement. The manufacturer rates the mean time between failures at 180,000 hours. It is built for continuous duty in servers, industrial computers, inverters and similar high-end equipment.

Suited for 24V chassis and rack enclosures

Buyers who need a 12V or 5V fan for standard desktop builds should look elsewhere, as this unit only operates at 24V. It also lacks PWM control, so systems that require four-wire variable speed headers will not be compatible.

Long-life bearing and high airflow headroom

The double ball bearing and silent IC series design deliver sustained airflow for dense component layouts and hot-running hardware. In environments that demand higher static pressure or redundancy through parallel arrays, a single 12025 unit may reach its limits.

Questions about this item

What power supply voltage must my system provide for this 24V fan?

The fan requires a 24V DC supply capable of delivering at least 0.31A through its three-wire connector.

Will the three-wire speed signal work with a motherboard that only has four-pin PWM headers?

Yes, the three-wire plug fits a four-pin header and the tachometer signal reports RPM while the fan runs at full 24V.

How can I confirm the fan is running at the expected speed after installation?

Monitor the RPM reading from the third wire in BIOS or monitoring software; a steady value indicates the speed measurement function is active.
