Compact 4 cm Maglev fan for tight builds

The 40 mm frame fits small-form-factor cases, 1U servers and embedded chassis where larger fans cannot be installed. Maglev bearings eliminate physical contact to reduce noise and extend operating life. It targets system integrators and hobbyists who need targeted airflow in confined spaces. Buyers who require high-volume cooling for full-size towers or multi-GPU setups should choose a larger fan.

Maglev bearing and standard mounting

The magnetic-levitation spindle removes friction, allowing quiet operation even at high RPM without lubricant degradation. Four corner screw holes match common 40 mm mounting patterns for direct case or heatsink attachment. A two-wire power lead connects to standard fan headers for simple speed control. No RGB lighting or PWM circuitry is included, keeping the design minimal for industrial and silent-PC use.
