A 4010 transparent sleeve-bearing fan runs at 12 V and .07 A on a two-pin connector
The OEM Industries A4010L12S is a 4010-format fan designed for graphics-card coolers and other small-form-factor thermal solutions. It runs on 12 V and draws only .07 A, making it suitable for low-power auxiliary cooling where space is limited. The transparent frame and sleeve bearing keep the unit light and simple.
A 2-pin connector provides basic voltage feed without PWM control, so speed is fixed by the supply voltage. The sleeve bearing offers quiet start-up in light-duty use, while the transparent blades let builders see airflow direction at a glance. No LED lighting is present, keeping the appearance neutral inside a case.
At .07 A the fan adds minimal load to a 12 V rail, and the sleeve bearing runs quietly at the low speeds typical for chipset or VRM cooling. It is not designed for high-static-pressure CPU heatsinks or dense radiator stacks where greater airflow or PWM regulation would be required.

The 2-pin connector supplies fixed 12 V power without a PWM signal, so fan speed cannot be regulated by the motherboard and runs at full voltage continuously.
The 40 mm square transparent frame needs a matching 40 mm mounting hole pattern and enough clearance for the sleeve-bearing rotor thickness.
Align the four corner holes, secure with screws, then connect the 2-pin plug to a 12 V header; the missed step is verifying airflow direction matches the heatsink fins.
