Compact 40 mm Server Fan

The Fans FD124020EB-N CAQ is a 40 mm square case fan with a 20 mm thickness. It runs on 12 V DC and draws 0.17 A through a three-wire connection. The unit is supplied new for server and workstation cooling.

Suited for Tight Chassis

This fan fits 40 mm mounting points in rack units and small enclosures where larger fans cannot be installed. The three-wire lead provides tachometer feedback for speed monitoring. Builders needing higher airflow, PWM control or larger frame sizes should consider other models.

Questions about this item

How do I connect the 3-wire plug on the FD124020EB-N CAQ fan?

Align the three-pin connector with the motherboard or controller header so the guide tab matches the slot, then press straight down until it clicks; reversing the plug bends the pins and prevents the fan from spinning.

When should I replace the FD124020EB-N CAQ fan?

Replace it when bearing noise becomes audible, airflow through the 40x40x20 mm frame drops noticeably, or the 12 V 0.17 A motor no longer spins up reliably.
