40×20 mm ball-bearing fan
The OEM Industries CHA4012EB-M is a compact 40 mm square cooling fan designed for tight spaces inside a chassis. It runs on 12 V and draws 0.24 A through a simple two-wire connection. The ball bearing and black frame suit builders who need a small, reliable airflow device for targeted component cooling.
Continuous low-speed airflow
At its rated voltage the fan delivers steady airflow without the ramp-up spikes seen in larger PWM models. The two-wire design means speed stays constant, so acoustic output and cooling capacity remain predictable during extended sessions. This behaviour suits applications where a fixed thermal baseline matters more than dynamic control.
Ball bearing and two-wire simplicity
The ball bearing reduces friction wear compared with sleeve alternatives, supporting longer uninterrupted operation in confined layouts. A two-wire lead plugs directly into a 12 V header or adapter, avoiding extra cables in small-form-factor builds. The 40×20 mm footprint fits legacy brackets and custom mounts where larger fans cannot be accommodated.

Soalan tentang produk ini
How much noise and heat does the 40×20 mm ball-bearing fan produce when running continuously?
The 40 mm fan uses a ball bearing and runs at 12 V, 0.24 A, so it spins steadily with moderate airflow and low acoustic output for a compact cooler.
What connector or header must my motherboard provide for the 2-wire 12 V fan?
A standard 2-pin 12 V fan header is required; the cooler has only two wires for power and ground with no PWM or speed-signal lead.
Will the 40 mm square frame fit alongside taller memory modules or larger heatsinks I already have?
The slim 20 mm thickness and 40 mm footprint leave ample clearance for most high-profile RAM and adjacent components.
