Compact 40 mm case fan

The SXDOOL mgt4012lf-o10 is a 40 mm square fan designed for tight spaces such as small-form-factor chassis, graphics-card heatsinks or north- and south-bridge coolers. It runs on 12 V DC and draws 0.08 A through a standard three-pin connector, making it a straightforward drop-in for legacy headers.

Low airflow and quiet operation

At 12 V the motor pulls only 0.08 A, so power draw stays minimal and heat output is negligible. The manufacturer highlights a mute, silent profile suited to noise-sensitive builds, and the non-LED black frame avoids light bleed in darkened cases.

Replaces worn 4010 coolers

This unit directly substitutes a failed or loud 40 mm × 10 mm three-wire fan in compact enclosures, GPU shrouds or chipset heatsinks. The upgrade is worthwhile when the original cooler has seized, developed bearing whine or no longer spins at full speed.

Questions about this item

How do I install the 40mm fan with its 3-pin connector on a motherboard header?

Align the three pins with the motherboard fan header, press firmly until seated, and route the cable clear of moving parts; the keyed connector prevents reverse insertion.

What maintenance will the sleeve-bearing 4010 fan need over time?

Expect the sleeve bearing to eventually dry out; when noise rises, replace the entire 40mm unit as bearings are not user-serviceable.

At what point does the 0.08A current limit restrict sustained cooling performance?

The fixed 0.08A draw caps maximum airflow, so under continuous high heat the fan cannot spin faster to increase cooling.
