Compact 1U cooler for dense servers

The Supermicro FAN-0085L is a 40 x 40 x 56 mm counter-rotating CPU air cooler built for 1U rackmount chassis. It targets system integrators and administrators who need reliable thermal performance in space-constrained environments where standard tower coolers cannot fit.

Counter-rotating design boosts airflow

The single fan spins at 13300 rpm and delivers 26.4 CFM through the heatsink. Counter-rotating blades reduce turbulence inside the narrow duct, so the unit moves more air per millimetre of height than a conventional single-direction fan of the same footprint.

Direct 6-pin mount simplifies installation

The cooler attaches with a 6-pin power connector that plugs straight into a compatible Supermicro server header, removing the need for adapters or cable routing. Clearance is tight in 1U layouts; verify motherboard keep-out zones before fitting to avoid interference with nearby components.

Questions about this item

How often will the 13300 rpm counter-rotating fan need cleaning or bearing replacement?

The 13300 rpm counter-rotating fan has no published service interval; dust buildup on the 40x40x56 mm heatsink is the main factor that reduces airflow over time.

What thermal limit appears first when the cooler runs continuously at 26.4 CFM?

Sustained 26.4 CFM airflow is limited by the 1U height; the small fin stack saturates before the 6-pin power delivery reaches its ceiling.

How much noise and heat does the 13300 rpm fan produce during all-day operation?

At 13300 rpm the fan generates noticeable high-pitched noise; the 6-pin connector draws only the power needed for 26.4 CFM, so waste heat stays low.
