Compact 40 mm PWM fan for 1U chassis

The Supermicro FAN-0065L4 is a single 40 mm case fan built for 1U server enclosures. It targets system integrators and IT staff who need a direct replacement for the original cooling module in compatible Supermicro chassis.

Fits SC813MF and SC113M frames with 4-pin control

The unit mounts in the standard 40×40×28 mm bay used by the SC813MF and SC113M chassis. Its 4-pin LP4 connector enables PWM speed regulation from the motherboard, freeing the builder from external fan controllers or voltage adapters.

Spins past 13 000 RPM for sustained airflow

Under continuous load the motor maintains speeds above 13 000 RPM, moving air through the tight 1U channel without throttling. The high rotational ceiling keeps component temperatures stable during extended compute tasks rather than only during brief bursts.

Questions about this item

At 13000 RPM what is the first limit you hit under sustained load?

The 40 mm frame moves less air than larger fans so static pressure drops quickly when filters or drive cages add resistance.

How much noise and heat does the fan produce when running all day at 13000 RPM?

At full speed the small 40 mm motor generates a noticeable high-pitched whine and pushes warm exhaust into the chassis.

Which motherboard header or chassis do I already need for the 4-pin PWM connector to work?

A 4-pin PWM header on the motherboard or a Supermicro SC813MF, SC113M or 111LT-360CB chassis provides the required control signal.
