Compact 40 mm fan for tight builds

This 40 mm frame fits small-form-factor and embedded systems where larger coolers cannot be mounted. The two-pin connector provides simple 12 V power without PWM control. It suits integrators who need basic airflow in confined spaces.

Low noise and modest power draw

At the rated 3000 rpm the fan produces 16 dB of noise while drawing 0.04 A at 12 V. The miniature bearing is specified for 60000 hours of continuous operation. Thermal performance scales with the unrestricted airflow the chassis allows.

Replaces worn or missing 40 mm two-pin fans

The unit drops into any 40 mm mounting pattern that accepts a 10 mm thick frame and a two-pin header. It is not suited for builds that require PWM speed regulation or higher static pressure than a miniature bearing can deliver.

Spurningar um þessa vöru

How do I mount the 40 mm fan and what orientation mistake should I avoid?

Secure the fan with four screws through the 40 mm frame; the airflow arrow on the housing must point toward the heatsink, not away from it.

When will the miniature bearing need replacement?

The bearing is rated for 60000 hours at the 3000 RPM reference speed; plan replacement once that runtime is reached.

At what noise level does the fan become noticeable during continuous operation?

Sustained running at the 3000 RPM reference produces 16 dB, which is the first audible limit you will encounter.
