OEM Industries 135mm Ball Bearing Fan

This 135mm cooling fan uses a ball bearing design for reliable airflow inside a PC case or switcher. It runs on 12V power through a standard two-pin connector and has no LED lighting. The transparent frame suits builds where internal visibility is preferred.

Suited for case and switcher airflow upgrades

Builders who need a simple 135mm replacement fan with ball bearing durability will find this model fits the requirement. It is not intended for CPU heatsink mounting or liquid-cooling radiators. Buyers who need PWM speed control or a tachometer signal should look at a different specification.

Two-pin power connector defines control

The 2-pin connector supplies 12V at 0.22A without a third wire for speed reporting or PWM input. Speed ranges from 2500 to 2999 rpm, delivering over 80 cfm at 25 to 30 dBA. This fixed-voltage design determines whether the fan matches your motherboard or controller capabilities.

商品問答

Should I pick the 2500 RPM or 2999 RPM version of this fan?

This model runs between 2500 and 2999 RPM as a single variant; there is no separate version to choose.

What does 80 CFM airflow mean when the fan is mounted in a case?

It can move up to 80 cubic feet of air per minute at full speed, though actual flow drops with grilles, filters or restricted vents.

What does the 2-pin connector limit compared to a 3-pin or 4-pin header?

The 2-pin connector supplies 12 V at 0.22 A but carries no tachometer or PWM signal, so the motherboard cannot monitor or control fan speed.
