Compact 40mm fan for tight builds

This OEM Industries cooler is a 40mm ball-bearing fan designed for cases or small-form-factor systems where space is limited. It runs on 12 V at 0.11 A and connects through a standard two-pin header. The unit is sold as a fan only without a heatsink or mounting hardware.

40mm frame with two-pin power

The single specification that determines fit is the 40 by 10 millimetre frame paired with a two-pin connector. Builders must verify their chassis or motherboard header matches this exact size and pin layout before purchase. No other mounting dimensions or voltage options are provided.

No bundled accessories or software

The package contains only the bare fan with two wires and no additional brackets, screws or control software. Users needing PWM speed control, LED lighting or a complete heatsink assembly will have to source those parts separately.

Questions about this item

What does the 40 mm fan size mean for airflow in a tight build?

The 40 mm diameter fits small form-factor cases and delivers targeted spot cooling where larger fans cannot mount.

What does the 2-pin 12 V 0.11 A connector limit for speed control?

The two-pin design runs at full 12 V constantly; no PWM or voltage regulation is possible from the header.

How much clearance does the 10 mm thickness need for mounting?

The 10 mm frame requires at least 10 mm of free space behind the mounting holes for the fan body to sit flush.
