OEM Industries KD1209PTS3 90mm Fan 12V 1.7W 2500-2999rpm 25-30dBA

Compact 90mm Case Fan

The OEM Industries KD1209PTS3 is a 90mm frame fan designed for tight chassis positions where larger coolers cannot fit. It draws 1.7W at 12V and uses a sleeve bearing for basic rotation. The two-wire power connector supplies voltage without speed reporting. Builders who need a simple airflow device for legacy brackets or small-form-factor enclosures will find it suitable. Buyers who want PWM control or a larger frame should look elsewhere.

Build Integration and Clearance

The 90mm square footprint and 25mm thickness match the 9025 mounting pattern common on older CPU coolers and compact case vents. Two-wire operation means the fan runs at full voltage unless the motherboard or controller reduces it externally. It frees up space around crowded socket areas or drive cages where 120mm units interfere. Installers without a 90mm mounting grid or without voltage-adjustment hardware cannot use it effectively.

Included Accessories and Software Impact

The package contains only the fan unit itself; no screws, adapters, speed controllers or software utilities are supplied. The absence of an LED keeps the device visually neutral in windowed builds. Without bundled mounting hardware the builder must provide compatible fasteners. No firmware or monitoring tools are included, so speed and noise remain fixed at the rated 2500 to 2999rpm and 25 to 30dBA range.
