12V 4-Wire Server Fan

The OEM Industries DBTA0838B2G is an 80 mm square fan built for server and workstation cooling. It draws 4.1 A at 12 V and uses a four-wire power connector for speed control. The unit is supplied new and matches the AVC 8038 form factor used in specific IBM chassis. ||

Fits IBM 74Y9392 L37134 Systems

This cooler is intended for maintainers replacing the original fan in IBM 74Y9392 or L37134 servers. It is not suitable for builds that require a different mounting pattern, voltage or connector pin-out. Buyers needing a thinner profile or LED lighting should look elsewhere. ||

80 mm x 38 mm Frame

The physical envelope is 80 mm wide and 38 mm thick, matching the AVC 8038 footprint. That exact thickness decides whether the fan seats correctly in the target server bay. Verify the chassis clearance before ordering.

Questions about this item

What does the 4-wire PWM connector on the DBTA0838B2G control?

The four wires carry 12 V power, ground, a tachometer signal and a PWM input so the motherboard can vary fan speed precisely.

Will the 80 mm by 38 mm frame fit my IBM 74Y9392 or L37134 server?

Yes, the square 80 mm by 38 mm housing matches the original cooler dimensions for those IBM server models.

How do I install the fan and which orientation mistake should I avoid?

Align the four mounting holes, screw the fan to the heatsink or chassis, connect the 4-wire plug to the board header, and ensure the airflow arrow points toward the heatsink fins.
