40 × 20 mm 12 V case fan

The Zyvpee KD1204PKS2 is a compact 40 mm square fan with a 20 mm thickness designed for CPU cooler and small-form-factor chassis use. It runs on 12 V power and draws 0.9 W through a two-wire lead. The black frame carries no lighting.

Two-wire ball-bearing installation

The fan mounts with standard 40 mm screw holes and connects via a bare two-wire cable that must be matched to a 12 V header or adapter. Polarity reversal will prevent the motor from starting. Ball bearings tolerate orientation changes but can develop audible rattle if the shaft is bent during fitting.

Builders needing a slim 40 mm replacement

Suits tight CPU coolers, router enclosures or switch gear that specify a 4020 form factor and a sub-1600 RPM ceiling. Not for PWM-controlled headers, four-pin ecosystems or anyone requiring speed reporting or RGB illumination.

Perguntas sobre este artigo

How can I confirm the 12 V fan is running at its rated speed after installation?

Measure the RPM with monitoring software or a hardware tachometer; the unit should read below 1600 RPM when powered from a 12 V header.

What comes in the box and what must be sourced separately?

The package contains the 40 mm × 20 mm ball-bearing fan with a 2-wire lead; mounting screws and any adapter cables are not included.

Which version should I choose for a 12 V header that supplies up to 0.9 W?

The KD1204PKS2 model is the only variant listed and matches a 12 V, 0.9 W, 2-wire specification.
