OEM Industries 1511FB-04W-B50 40mm 12V 0.46A 2-Wire CPU Cooler

Compact 40 mm cooler for tight builds

The OEM Industries 1511FB-04W-B50 is a square DC fan designed for small-form-factor systems where space is at a premium. It suits builders assembling thin clients, embedded boards or low-profile servers that need active CPU cooling without a tall heatsink. The two-wire 12 V connection keeps wiring simple for basic motherboard headers or direct PSU taps.

0.46 A draw sets the thermal ceiling

At 12 V and 0.46 A the fan delivers modest airflow adequate for low-TDP processors or chipset heatsinks in well-ventilated chassis. It will struggle with sustained loads on mainstream desktop CPUs or any component exceeding its limited static pressure. The 40 mm frame leaves no room for larger blades, so peak cooling capacity is inherently constrained.

Black plastic frame with two-wire lead

The all-black housing blends into dark interiors and the lack of LEDs avoids unwanted light in rack or industrial environments. A fixed two-wire cable means speed control is limited to voltage regulation; PWM headers will run the fan at full speed unless the board supports voltage mode. Mounting holes follow the standard 40 mm square pattern for direct screw attachment.
