The HD 5450 PCB is only 16.8cm long. Though the reference sample has a passive cooler, there is a fan header pictured above on the bottom right corner.

The heatsink has thick, broad fins with plenty of curves. The fin orientation doesn't seem to promote better cooling, looking more impressive than it likely is.

A padded backplate with four screws secures the heatsink to the card. Like the Asus HD 5750, the 5450 has the same mounting holes spaced 43mm apart.

The heatsink seems to press against the memory chips but there's no thermal interface material between them. In addition there are two rubber pads at the edge to keep it from accidentally crushing anything.
