90x38mm PWM Fan for CPU Cooling

The OEM Industries 3615ML-04W-B76 V03 is a 90x38mm DC fan built for CPU air coolers. It runs on 12V at 1.6A and uses a four-pin PWM connector for speed control. The ball bearing and black frame suit continuous operation in compact builds.

Replaces 3-pin or smaller 9cm fans

Swapping a three-pin 9cm fan for this four-pin PWM model adds automatic speed regulation without extra controllers. The jump is worth it when the motherboard header supports PWM and the cooler mounting holes match the 90x38mm footprint.

Limited to 12V four-pin headers

The fan requires a standard 12V four-pin PWM header; it will not run from a three-pin header without losing speed control. No RGB or addressable lighting is present, so it cannot sync with lighting ecosystems. The 38mm thickness may not fit slim coolers.

Questions about this item

What clearance does the 90x38mm frame need to fit in my case?

The fan measures 90mm by 90mm and is 38mm thick, so allow at least that much space between the mounting surface and any side panel or component.

How do I connect the 4-pin PWM plug and which orientation is correct?

Align the keyed 4-pin connector with the motherboard header so the tab matches the notch, then press straight in until it clicks.

When should I expect to replace the ball-bearing fan?

Ball bearings typically last for years of continuous use; replace the unit when noise increases noticeably or RPM drops below expected levels.
