The heatsink consists of a pressed and bend sheet metal strip of ripped shape, whose surface area is approx. equal to a surface area of an electronic component (2) which comprises a centrally positioned heat slug (3) with a small surface area. A number of bends (9) of the heatsink (1) contact the heat slug of the component in an assembled condition. The lower bends of the heatsink are connected to upper bends (8) by rips (7), and the external rips comprise projections (18) above the upper bends, which have inwards directed edges (14). The edges hold a fan (4) in a vertical position, and the fan rests on two exterior bends which comprise a snapper (13) which holds the heatsink in a horizontal position. The lower ends of the outer rips comprise edges which are directed inwards, and which are held in respective extrusions of a socket of the component, so that the lower bends are pressed against the heat slug and that the projections are attached to the fan.
