Compact 80 mm 12 V case fan

The SXDOOL 3110gl-b4w-b79 is an 80 mm frame fan that runs on 12 V DC and connects through a standard 3-pin header. Dual ball bearings and a rated speed of 4200 RPM deliver 49.6 CFM of airflow for targeted component cooling.

Check header voltage and mounting space

Verify that your motherboard or fan controller provides a 3-pin 12 V header and that the chassis offers an 80 × 80 mm mounting pattern with 25 mm depth clearance. The lead length is 14 cm so confirm the cable reaches the header without strain.

Replaces worn 80 mm sleeve-bearing fans

This unit suits builders swapping out ageing 80 mm sleeve-bearing fans that have become noisy or lost RPM. The 70000-hour dual-ball rating and 45.6 dBA output make the upgrade worthwhile when sustained high airflow matters more than silent operation.

Questions about this item

Does the fan ship with mounting screws or must they be purchased separately?

The package contains the 80 × 80 × 25 mm fan with a 14 cm 2510 3-pin lead; mounting screws are not included and must be sourced separately.

The spec lists 4 200 RPM and 49.6 CFM — is that the only speed option or are lower-voltage versions available?

This model is the 12 V 3110GL-B4W-B79 rated at 4 200 RPM ± 5 % and 49.6 CFM; no other voltage or speed variants are offered for this part number.

At 4 200 RPM and 45.6 dBA, how loud will the fan be inside a typical mid-tower case?

Expect a clearly audible 45.6 dBA at full speed; the 3-pin connector allows voltage control so the motherboard can reduce RPM and noise when full airflow is not needed.
