Zyvpee DS09225R12H PFAF 90x25mm 12V 0.41A PWM case fan

90 mm PWM fan for CPU coolers

The Zyvpee DS09225R12H PFAF is a 90 mm square frame case fan built for CPU cooler mounting. It runs on 12 V power through a standard four-pin PWM connector so motherboard speed control works directly. The hydraulic bearing keeps noise low during continuous operation. The all-black, non-LED design suits builds that avoid lighting.

Installation uses four mounting holes

Four corner holes accept standard 90 mm screws or rubber grommets for vibration isolation. The 25 mm thickness fits most tower coolers and tight chassis bays without fouling memory slots or VRM heatsinks. PWM control requires a four-pin header; a three-pin header will run the fan at full speed only. The 0.41 A draw is modest but verify header current limits if daisy-chaining multiple units.

3000 to 3499 RPM range for focused airflow

At the lower end the fan moves enough air for modest thermal loads while staying quiet. Near the top of the range it delivers stronger static pressure for dense fin stacks but audible noise rises accordingly. The 90 mm diameter limits total airflow versus larger fans so it suits targeted component cooling rather than high-volume case ventilation. Builders needing higher CFM should consider larger frame sizes.
