Zyvpee KD1209PTS2 90×25 mm 12 V 1.7 W 2-wire case fan

Compact 90 × 25 mm 12 V case fan

The Zyvpee KD1209PTS2 is a 90 mm square frame fan with a 25 mm thickness, designed for direct 12 V DC operation. It draws 1.7 W and spins below 1600 RPM using a sleeve bearing, providing basic airflow for tight chassis or heatsink mounting. The two-wire power connector supplies voltage without speed reporting or PWM control.

Suits builds needing a slim 90 mm replacement

This unit fits any bracket cut for the 90 × 25 mm footprint and a two-pin 12 V header. It is not suited for systems requiring PWM speed regulation, tachometer feedback, or higher static pressure than a sub-1600 RPM sleeve-bearing design can deliver. Builders who need LED lighting or a different bearing type should look elsewhere.

Critical spec: 90 × 25 mm frame

The physical envelope of 90 mm by 25 mm and the two-wire 12 V connector are the sole determinants of fit and electrical compatibility. Verify that the mounting holes match the 90 mm pattern and that the header supplies plain 12 V before purchase.
