40 mm 12 V Maglev Case Fans 2-Pack

Two 40 mm maglev cooling fans operate at 12 V DC and draw 1.1 W each. The 3-wire connection provides speed feedback for motherboard monitoring. Compact dimensions suit tight chassis, small-form-factor builds and equipment racks where space is limited.

Ideal for Small Chassis and Tight Spaces

Suits builders fitting 40 mm mounts in mini-ITX cases, HTPC enclosures or 1 U server trays. Not for systems needing larger-diameter airflow, higher static pressure or PWM speed control via a 4-pin header.
