Fans AFB0512HBSize 50x50x15mm 12V 0.15A 18dBA 4P PWM case fan

SKU CH-TTJF-F27W3 MPN AFB0512HBSize

A 50×50×15 mm axial fan with double ball bearings, 12 V PWM control and 18 dBA noise for compact case or server cooling

  • Double ball bearings extend service life and reliability
  • 18 dBA noise level keeps systems quiet
  • PWM 4-pin control enables precise speed adjustment
  • 12 V 0.15 A draws minimal power
  • 50 x 50 x 15 mm fits compact builds

Compact 50 mm PWM fan

The 50 mm by 50 mm by 15 mm axial fan runs on 12 V and draws 0.15 A through a motherboard 4-pin PWM header. It targets builders who need directed airflow in tight spaces such as small-form-factor cases, server radiators or power-supply retrofits.

Replaces louder 5015 units

The double ball bearing design cuts acoustic output to 18 dBA while maintaining sufficient static pressure for heat-exchanger stacks. The jump is worth it when an existing 5015 fan has become noisy or when a maintenance-free bearing is required for continuous operation.

Steady output at rated speed

PWM control lets the motherboard match RPM to thermal load so the fan sustains its 18 dBA rating instead of spiking during short bursts. Rated life of 10.0000 hours reflects constant operation at standard voltage rather than a peak figure.

Questions about this item

Will the 50 mm by 50 mm by 15 mm frame fit my 5015 mounting holes?

Yes — the fan body is exactly 50 mm square and 15 mm thick, matching the standard 5015 cut-out.

How do I connect the 4P PWM plug so the motherboard actually controls the speed?

Plug the 4-pin connector into a motherboard PWM header and enable PWM mode in BIOS; the fourth wire carries the tachometer signal back to the board.

When should I expect to replace the double ball bearing fan?

The manufacturer rates the bearing life at 10.0000 hours; listen for rising noise or vibration as the practical indicator.
