Compact 40 mm Cooling

The Delta FFB0412EN is a 40 x 40 x 28 mm axial fan built for tight enclosures that need focused airflow. It runs on 12 V DC at 0.24 A and spins at 25000 RPM to deliver 32.9 CFM with 4.440 inches of water static pressure. Double ball bearings support continuous operation from -10 °C to 70 °C.

For Dense Builds Not Silent Rigs

This fan suits server nodes GPU coolers or industrial chassis where high static pressure matters more than low noise. The 64.0 dB(A) axle noise rules it out for quiet workstations or bedroom PCs. Buyers who need a larger frame or PWM speed control should look elsewhere.

Four Pin 4 Lead Connector

The termination uses a 4-lead 4-pin header so the motherboard or controller can read tachometer signals and regulate voltage. Verify that your board supplies a matching header before purchase.

Questions about this item

How do I connect the 4-pin lead to my motherboard and which step is often missed?

Align the keyed 4-pin connector with the motherboard header and press until the latch clicks; the step many miss is routing the cable so the latch stays engaged and the fan does not vibrate loose.

What maintenance will the double ball bearing need over time?

The double ball bearing is sealed and requires no lubrication; if noise rises above the rated 64.0 dB(A) after long use the fan should be replaced rather than serviced.

At what temperature does the fan hit its operating limit during sustained loads?

The rated operating ceiling is 70 °C (158 °F); sustained ambients above that will exceed the fan's specified range.
