Product Identity

The OEM Industries CHB12012CB is a 120mm cooling fan built for CPU air coolers. It suits builders who need a straightforward replacement or case airflow upgrade without LED lighting. The two-wire design fits basic 12V headers on most motherboards or fan controllers. Buyers who want PWM speed control or RGB illumination should look elsewhere.

Critical Specification

The fan uses a 2-ball bearing rated for 12V at 0.38A. This bearing type generally offers longer life than sleeve alternatives in continuous operation. Speed ranges between 2500 and 2999rpm depending on voltage and load. The 2-wire connector means speed is regulated by voltage only, not by a PWM signal.

Sustained Operation

Under constant load the ball bearing maintains consistent rotation without the wear pattern common in sleeve designs. Airflow remains steady across the 2500 to 2999rpm band as the motor draws 0.38A. The simple two-wire feed avoids signal noise that can affect PWM fans on long cable runs. The black frame and blades blend into standard builds.

Questions sur cet article

How much airflow does a 2500-2999 rpm fan move in a typical case?

At 2500 to 2999 rpm the 120 mm blade pushes a strong, focused stream through heatsinks or case grilles; actual CFM depends on static pressure from your specific mounting.

What does the 2-wire power connector limit for speed control?

The two-wire lead supplies 12 V at 0.38 A with no tachometer or PWM line, so the motherboard can only vary voltage, not read rpm or use 4-pin PWM profiles.

Will the 120 mm frame fit standard 120 mm mounting holes?

Yes, the 120 mm square frame matches the industry 120 mm hole pattern, so it bolts directly to case fan mounts, radiators or heatsink brackets.
