Provided is a heatsink with a fan with which it is possible to: achieve an overall decrease in thickness and size; provide high heat-dissipating efficiency while maintaining quietness; realize low-cost implementation; prevent a decrease in heat-dissipating efficiency and the generation of noise without the overall shape thereof in plan view being particularly limited to a circular shape, thereby making it possible to adopt a shape in accordance with the space in an electronic apparatus housing and to maintain the freedom of housing design. This heatsink with a fan is provided with: a metal heat-receiving substrate 2; a centrifugal fan 3 disposed on an upper surface 21 side of the heat-receiving substrate 2; metal plate-shaped walls 4 which are vertically disposed on the upper surface 21 of the heat-receiving substrate 2 at positions around and opposing an outer peripheral portion of the centrifugal fan 3 having air-outlets, and in which a plurality of through-holes 41 are formed in board surfaces 40 opposing
