Compact 40 mm cooling fan

This 40 by 40 by 20 mm case fan fits tight spaces where larger units cannot. The three-wire connection supports speed monitoring for basic system control. At 1.4 watts it draws minimal power from the supply. The KDE1204PKVX model is suited to small-form-factor builds and targeted component cooling.

Slim 20 mm profile eases mounting

The thin frame allows installation in shallow enclosures or between closely spaced cards. Standard 40 mm screw spacing matches common chassis hole patterns. Three-wire cabling reaches nearby headers without strain. Silent operation keeps background noise low in quiet workstations or home-theatre PCs.
