Fans KDE1204PKV3 4020 40x40x20mm DC 12V 0.40W Case Fan 2pcs

SKU CH-W7TB-XZ05B

Pair of 40x40x20 mm DC 12 V 0.40 W case fans for compact server or inverter cooling

  • 40 mm square footprint fits tight server chassis
  • 20 mm slim profile clears low-clearance components
  • 12 V DC input matches standard power rails
  • 40 W draw keeps inverter heat low

Compact 40 mm DC cooling pair

Two 40 x 40 x 20 mm fans operate on 12 V DC power and draw 0.40 W each. The KDE1204PKV3 model fits tight server or inverter chassis where space is limited. Supplied as a matched pair for balanced airflow.

Ideal for confined 12 V builds

Suits technicians refreshing small-form-factor enclosures that accept 40 mm frames. Not for systems needing larger fan mounts, higher static pressure or PWM speed control. Buyers requiring different voltage or connector types should look elsewhere.

Questions about this item

What power connector does the KDE1204PKV3 fan need to run?

It requires a 12 V DC supply; the two-wire lead plugs into a standard motherboard or fan-controller header rated for 12 V.

Will these 40×40×20 mm fans fit in the same mounting holes as older 40 mm fans I already have?

Yes, the 40 mm square frame and 20 mm thickness match the common 4020 footprint, so existing 40 mm screw patterns line up.
