Compact 40mm Cooling Fan

The OEM Industries FD124028MB-P is a 40mm square frame fan designed for tight clearance cooling in small form factor systems or as a replacement on legacy CPU heatsinks. Its two ball bearing construction targets builders who need reliable long term operation in confined spaces. The two wire power lead suits basic voltage control without PWM signalling.

Two Wire Voltage Control Limits

Speed varies only with supply voltage so the fan runs at a fixed 7000 RPM when fed the full 12 V and 0.20 A rating. There is no fourth wire for motherboard PWM regulation or tachometer feedback so automatic fan curves and speed monitoring are unavailable. Builders who need closed loop speed control or variable noise profiles cannot use this model.

13 CFM Airflow at 34.5 dBA

At the rated 7000 RPM the fan moves 13 CFM while producing 34.5 dBA which suits low profile heatsinks or chipset coolers with modest thermal loads. It will not provide enough static pressure or volume for larger tower coolers or high TDP processors. Systems requiring substantially more airflow must use a larger frame or higher performance design.

Domande su questo articolo

Is the FD124028MB-P the only 40mm two-ball-bearing fan offered in this series?

The FD124028MB-P is the single model presented; it ships as a 40 mm frame with two-ball bearings, 12 V 0.20 A input and a two-wire power lead.

What does the 7000 RPM rating actually deliver inside a case?

At 7000 RPM the fan moves 13 CFM of air while producing 34.5 dBA, giving strong airflow for tight 40 mm mounts such as small-form-factor CPU coolers or GPU shrouds.

How does the two-wire connector limit speed control?

The two-wire lead supplies fixed 12 V power only, so the fan runs constantly at 7000 RPM; voltage regulation or PWM control requires a three- or four-wire header instead.
