What to know before buying

Listing details to confirm

The listing gives a 158 mm cooler height and a separate dimensions entry of 14L x 15.7W x 15.8H centimetres. Fan speed is stated as 1500RPM±10% in the fan description but as 1500 RPM elsewhere, and its noise figure is expressed as a maximum in the feature text but as a plain value in details. The title's top-cover wording does not establish an extra bundled case. Confirm clearance and package contents for the selected listing.

The supplied evidence contains aggregate ratings but no customer-review comments, so it cannot show what buyers liked or criticised. The rating distribution is mostly five-star with a small two-star share, but does not explain the reasons. Treat it as a limited snapshot rather than evidence of cooling, noise or installation outcomes.
