Compact 50 mm frame for tight builds

The SXDOOL DLF0512LB is a 50 by 50 by 20 mm case fan built for small-form-factor chassis, GPU coolers, power-supply retrofits and server enclosures where space is at a premium. It targets builders who need focused airflow in confined layouts rather than high-volume case circulation.

12 V 2.4 W limit defines usable airflow

Running on a 12 V DC supply at 0.2 A, the motor draws 2.4 W and spins at 6000 RPM to deliver 15.93 CFM at 0.186 in H₂O static pressure. The double ball bearing supports continuous duty, but the fixed voltage and modest pressure curve restrict use to low-impedance paths such as open heatsinks or short ducts.

Standard two-wire 12 V hook-up

The fan connects to any 12 V header or molex adapter with no PWM control; speed is constant unless the supply voltage is lowered. Clearance is the main pitfall: the 20 mm thickness and 50 mm square footprint leave no margin in many slim brackets, so verify mounting-hole spacing before ordering. Buyers needing variable speed or larger airflow should look elsewhere.

Questions about this item

What does the 5020 size mean for fitting this fan?

The 5020 code shows a 50 mm square frame that is 20 mm thick, so it fits standard 50 mm mounting holes in tight chassis or power-supply slots.

How much airflow does 15.93 CFM actually move inside a case?

At 15.93 CFM the fan pushes a modest stream of air through heatsinks or restricted vents, enough for targeted component cooling rather than whole-case turnover.

What does the 12 V DC rating limit in practice?

The fan runs only from a 12 V DC header or supply; it cannot be powered from 5 V or USB ports without a step-up converter.
