Abstract: The present application relates to a flexible fan module. The flexible fan module is to utilize the concept of male-female type connection to modulize a fan assembly, thereby not only having a concise mechanism and rapidly dismantling a fan main unit, but also being easily applicable in the number of one or more fan modules to the mechanism of a target device of which heat is desired to be dissipated, such as to the main housing of a personal computer, wherein no other designs of fixing mechanism are needed. The flexible fan module comprises: a fan main unit; a female member for fixing the flexible fan module on the target device; a female connecting member for connecting the female member to the fan main unit; a male member closely fitting into the female member; a handler member, wherein the handler member is connected to the fan main unit by penetrating the male member.
