Compact 70 mm cooling fan

This 70 mm case fan fits tight chassis spaces and delivers direct airflow for small-form-factor builds or CPU coolers that need a slim profile. It runs on 12 V power through a standard three-pin connector. The ball bearing design supports continuous operation in desktop and server environments. Non-LED black frame keeps the look understated.

Three-pin DC control

The fan uses a three-pin power connector for direct voltage control from a motherboard header or fan controller. Speed reaches up to 1600 RPM under full voltage. Current draw is 0.1 A at 12 V. No PWM signal wire is present so speed varies with voltage alone. Buyers who need four-pin PWM regulation should choose a different model.

Quiet low-speed operation

Noise output stays between 20 and 25 dBA during normal running. The slim 15 mm thickness and ball bearing keep vibration low at typical speeds. Power consumption remains modest at 12 V and 0.1 A. Builders who require higher static pressure or louder maximum airflow will need a larger or faster fan.

Questions about this item

What does the 1600 RPM ceiling mean once the fan is running inside a case?

The fan spins up to 1600 RPM, moving air through a 70 mm frame at 12 V and 0.1 A while keeping noise between 20 and 25 dBA.

How does the 3-pin connector control speed in practice?

The 3-pin DC connector lets the motherboard vary voltage to adjust RPM; it does not carry a PWM signal.

What clearance does the 15 mm thickness need for mounting?

The 70×70×15 mm square frame fits standard 70 mm fan mounts with 15 mm depth clearance.
