Listing details to confirm
Listing details are inconsistent: the product dimensions are given as 12.5L x 13.5W x 15.4H centimetres and 125 x 135 x 155 mm, while another feature gives a height of 154mm. The title refers to a 120mm PWM fan, but the detailed description names two fans. The included-components field says “CPU Water Cooler” despite the product being described as an air cooler. Confirm exact dimensions and supplied components for the selected listing.
