A mechanical assembly, for regulating the temperature of an electronic device, includes a gimbal and a heat-exchanger which is attached to the gimbal. The gimbal includes a base member, a carrier member, and a spring which has--1) a first end with a rigid coupling to one of the base and carrier members, and 2) a second end with a slideable coupling to the remaining member. The slideable coupling prevents any gap from occurring between the heat-exchanger and the electronic device when they are pressed together.
