80 mm square case fan with ball bearing and 3-pin 12 V power connector
This 80 by 80 by 15 mm fan fits tight CPU cooler mounts and small-form-factor builds. It runs on 12 V DC and draws 0,40 A through a standard three-pin connector. The ball bearing is chosen for durability in continuous operation. No LEDs are fitted, keeping the appearance plain black.
At the rated 12 V the motor pulls 40 W, so heat output stays modest inside a closed chassis. The ball bearing avoids the rattle that sleeve bearings develop over time. With no PWM wire the fan runs at a fixed voltage, giving a predictable acoustic profile. The 15 mm thickness leaves room for heatsink fins on either side.
Under continuous load the 0,40 A draw does not change, so thermal output remains stable for long rendering or compile sessions. The three-pin header supplies full voltage without speed scaling, meaning airflow stays constant from start to finish. Ball bearing life is rated for extended duty cycles at this power level.

Align the keyed tab on the 3-pin plug with the notch on the 12 V fan header and press straight down; the third wire is the tachometer signal, so reversing it stops RPM reporting.
Ball bearings typically last 40 000 hours at 40 °C; rising whine or vibration after continuous operation signals the bearing is worn and the 80 mm unit should be swapped.
The motor is rated for continuous operation up to 40 °C ambient; exceeding that reduces bearing life and can trigger thermal shutdown.
