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.
