90 mm 4-Wire CPU Air Cooler

The OEM Industries PMD1209PTB1-A is a compact 90 mm square cooler built around a SUNON 9225 fan. It targets system builders who need a low-profile air cooler for small-form-factor or replacement applications. The unit draws 5.6 W at 12 V and uses a standard four-wire connector for speed control.

Four-Wire PWM Connector and Square Mount

The 4-wire interface enables motherboard-controlled fan speed without extra adapters. A square frame matches common 90 mm mounting patterns found on many OEM boards and slim tower chassis. No LED lighting is present, keeping the appearance neutral for professional or embedded builds.

5.6 W Power Draw and PWM Thermal Control

At 5.6 W the fan adds minimal load to a 12 V rail, leaving headroom for the rest of the system. Pulse-width modulation lets the motherboard lower RPM when the CPU is idle, reducing audible noise during light workloads. Under sustained load the cooler maintains airflow proportional to the thermal demand reported by the sensor.

Questions about this item

Does the 4-wire PWM connector cap fan control to 12 V operation only?

The 4-wire PWM connector runs from a 12 V supply and draws 5.6 W, so speed control is limited to that voltage rail.

What mounting pattern does the 90 mm square frame need on the motherboard?

The 90 mm square frame uses the standard 90 mm hole spacing, so it fits any board with matching 90 mm mounting holes.

How is the cooler installed, and which step is often missed?

Align the four mounting holes, secure the supplied screws in a cross pattern, then plug the 4-wire connector into the CPU fan header — forgetting the PWM wire leaves the fan at full speed.
