The utility model provides a cooling module. The cooling module is provided with a radiator and a fan, wherein the radiator comprises a core body and hydroeciums arranged on two sides of the core body; the fan is mounted on the radiator and comprises a fan housing; radiator side mounting components are respectively arranged on the hydroeciums on the two sides; fan side mounting components which are jogged with the radiator side mounting components are respectively arranged on the two sides, corresponding to the hydroeciums, of the fan housing; convex parts which are convex towards the side of the radiator and are abutted with the edge of the radiator are arranged on at least one edge of the two side edges not corresponding to the hydroeciums, of the fan housing. Through the adoption of the cooling module, a gap between the radiator and the fan can be effectively reduced, and the purposes of vibration reduction and noise reduction can be achieved.
