120 mm ball-bearing case fan with 12 V 1.95 A three-pin power and 38 mm depth
The OEM Industries AD1212HB-F93GP is a 120 mm square DC cooler built around an ADDA fan running at 12 V and 1.95 A. It uses a three-pin power connector and ball bearings for rotation. The unit ships as a fan-only module without integrated LED lighting.
Ball bearings provide consistent rotational stability under continuous load. The 12 V 1.95 A rating defines the electrical demand during normal operation. No LED circuitry is present so the entire power budget serves the motor directly.
The three-pin connector plugs into any compatible motherboard or fan-controller header. Because the package contains only the fan, builders must supply their own heatsink or mounting hardware. The 38 mm thickness requires sufficient clearance between the CPU socket and nearby components.

Align the three pins with the motherboard CPU_FAN header, press straight down until seated, then enter BIOS to enable DC voltage control so the 12V 1.95A motor can vary speed instead of running at fixed maximum.
The ball bearing is rated for long life, but after several years of continuous 12V operation the lubricant degrades, causing audible rumble; at that point the entire 120x38mm fan unit is replaced because it is a non-serviceable assembly.
Sustained 12V 1.95A draw heats the motor windings until internal thermal protection engages, reducing RPM to protect the ball bearing and coil insulation from overheating.
