Compact 90 mm magnetic-bearing fan

This 90 mm case fan uses a magnetic barometric bearing and runs at 2500-2999 RPM to deliver 20-25 CFM at 35-40 dBA. It suits compact chassis or GPU coolers that accept a 92 mm square frame and a 12 V three-pin header. Builders who need PWM speed control or addressable lighting will not find those features here.

Three-pin power only

The unit ships with a standard three-pin connector rated for 12 V and 1.2 W; no PWM wire, splitter cables or mounting screws are included. Software control is limited to voltage-based regulation from the motherboard header. Users who expect a four-pin PWM interface or bundled accessories must source them separately.

Straightforward 92 mm mounting

Installation follows the usual 92 mm hole pattern with four screws; the 25 mm thickness fits most standard locations. The three-pin plug keys one way, so orientation errors are rare. Over-tightening screws can distort the thin frame, and the fixed-speed range may feel loud in silent-focused builds.

Questions about this item

How long does the magnetic barometric bearing last before it needs replacing?

The magnetic barometric bearing has no physical contact surfaces, so it does not wear out like sleeve or ball bearings and typically runs for the life of the fan without replacement.

At the top speed of 2999 RPM, does airflow or noise become the limiting factor first?

At 2999 RPM the fan moves 25 CFM while producing 40 dBA; the acoustic ceiling is reached before the airflow ceiling, so noise limits sustained high-speed operation.

What is the power draw and heat output when the fan runs continuously at 12 V?

The motor is rated at 1.2 W at 12 V, so continuous operation draws 1.2 W and dissipates the same amount as heat inside the case.
