OEM Industries 50mm DC Square Cooler

This OEM Industries 2006ML-04W-S39 is a 50mm square cooler designed for compact CPU air cooling. It uses a ball bearing fan running at 12V and 0.07A with a 3-pin power connector. The unit is supplied new in black without LED lighting.

Builders needing a low-profile 5015 replacement fan

This cooler suits builders who need a direct 50mm by 15mm replacement for tight spaces such as small form factor cases or rackmount servers. It is not for users who require PWM speed control via a 4-pin header or who want integrated RGB illumination for aesthetics.

3-pin power connector determines motherboard

The 3-pin connector provides voltage-based speed regulation only. Buyers must confirm their motherboard header supports 3-pin DC control before purchase. A 4-pin PWM header will run the fan at full speed without automatic adjustment.

Questions about this item

What are the exact mounting dimensions for the 50mm fan frame?

The square frame measures 50mm on each side with a thickness of 15mm, matching the 5015 form factor.

How do I connect the three-wire lead to a standard motherboard header?

Align the keyed 3-pin connector with the 12V, ground and tachometer pins on the board header; forcing it backwards bends the pins.

When should the ball-bearing assembly be replaced?

Replace the unit once the rotor develops audible rumble or the speed signal drops out, typically after several years of continuous 12V 0.07A operation.
