Fans

Fans 1504 Micro Case Fan 15x15x4mm 3.3V/5.0V

SKU CH-CMBJ-YKBF2

Ultra-compact 15×15×4 mm axial fan runs on 3.3 V or 5.0 V DC, spins at 10 000–17 000 RPM, moves 0.4 CFM at under 35 dB-A, and uses a hydraulic bearing with 50 mm leads

  • Ultra-compact 15x15x4mm size fits tight spaces
  • Hydraulic bearing runs under 35 dB-A for quiet operation
  • Dual-voltage 3.3V/5.0V compatibility simplifies integration
  • Low 0.2W power draw at 0.03A current
  • CE and ROHS certified for regulated environments

Ultra-compact 15 mm cooling fan

The Fans 1504 micro case fan measures 15×15×4 mm and runs on 3.3 V or 5.0 V DC. It delivers 0.4 CFM airflow at 10 000–17 000 RPM while drawing only 0.2 W and 0.03 A. Noise stays below 35 dB-A, and the unit carries CE and RoHS certification.

Simple two-wire installation

The fan uses a 50 mm two-wire lead that connects directly to a compatible 3.3 V or 5.0 V header. Its free-standing mount and plastic blades allow placement in tight enclosures without brackets. Ensure the supply voltage matches the fan rating; reversing polarity or exceeding 5.0 V can damage the hydraulic bearing.

Ideal for space-constrained electronics

This fan suits builders cooling small-form-factor PCs, embedded boards, medical devices or industrial gear where a 15 mm footprint is required. Buyers who need higher static pressure, larger airflow volumes or PWM speed control should look at larger frame sizes.

Questions about this item

How can I confirm the 1504 micro fan is running at the rated speed after installation?

The fan operates between 10000 and 17000 RPM; listen for a quiet hum below 35 dB-A and feel steady airflow from the 15x15x4 mm frame.

What comes with the 1504 micro fan and what must I source separately?

The unit includes the axial fan with a 50 mm two-wire lead for 3.3 V or 5.0 V DC; mounting hardware and a power connector are not supplied.

Should I choose the 3.3 V or 5.0 V version of the 1504 micro fan for my build?

Select the voltage that matches your board header — 3.3 V for low-power headers drawing 0.03 A, or 5.0 V for standard headers delivering 0.2 W.
