What to know before buying

Listing details to confirm

Listing details are inconsistent or unconfirmed: dimensions appear as 120 x 120 x 38 mm in one description and 12 x 12 x 3.8 cm with a 580 g weight in another, while noise is listed as both 50.1 dBA and 52.2 db. The title and feature text describe a 12 V DC fan with a US AC plug and speed controller, but the connector details do not fully clarify the power arrangement. Confirm these points for your setup.

Aggregate ratings lean positive, with most ratings in the five-star category and a smaller share in the four- and three-star categories. This is a modest rating sample without written feedback, so it does not explain customer experiences or confirm the listed airflow, noise or power details. Buyers should treat those specifications as listing claims and verify the fit and power arrangement for their intended use.
