40 mm 12 V case fan

This 40 mm square fan runs on 12 V and draws 1.8 W. The KDE1204PFVX model uses a three-line connection for speed reporting or control. It suits compact chassis or small-form-factor builds where space is tight.

Questions about this item

Will the 1.8 W power draw limit continuous operation in a 12 V system?

The fan is rated at 1.8 W on 12 V, so sustained use stays within that power envelope.

How much noise and heat does the 4010 produce when running all day?

At 1.8 W the 40x40x10 mm frame generates modest heat and typical small-fan noise levels during continuous operation.
