Compact 40 mm case fan

The SXDOOL 40 mm case fan measures 40 by 40 by 20 mm and runs at 5000 to 5499 RPM on a 5 V supply. It delivers 5 to 10 CFM of airflow while producing 20 to 25 dBA of noise. A two-pin power connector provides simple voltage feed without speed reporting or PWM control.

Two-pin voltage control

The two-pin connector means the fan runs at full speed whenever power is applied; motherboard headers cannot modulate RPM or monitor rotation. Builders needing variable speed or tach feedback must add an external controller or choose a three- or four-pin alternative.

Sleeve-bearing durability

A sleeve bearing rated for 60000 hours at up to 75 °C keeps the 25 g frame running quietly at 22 dBA typical. The black, non-LED blades suit compact enclosures such as small-form-factor PCs, NAS units or industrial chassis where space is tight and lighting is unwanted.

Questions about this item

Should I pick the 5000 RPM or 5499 RPM version of this 40mm fan?

The fan operates across a 5000-5499 RPM range depending on load, so there is no separate version to choose.

What does the 6.24 CFM airflow figure mean once the fan is installed in my case?

At 6.24 CFM the fan moves a modest volume of air through a 40mm frame, suited to spot-cooling tight spaces rather than whole-case airflow.

How does the 2-pin connector limit speed control in practice?

A 2-pin connector supplies fixed 5V power, so the fan runs at its rated 5000-5499 RPM without PWM or voltage regulation.
