This disclosure describes an adjustable force load cell that can be utilized in heatsinks with multiple load cells. Adjustable force load cells enable dynamic adjustment of the total force imposed by the heatsink onto a component. In addition to a screw, spring, and washers, the adjustable force load cell includes a collar and features to the screw that enables the collar to move along the axis of the screw and be set at multiple fixed locations. As the collar moves along the axis of the screw, it enables the spring to either compress or expand beyond an original set length. Graduation marks are provided to visualize and calibrate different settings and corresponding forces. A locking mechanism such as a jam nut is provided to fix the collar at a suitable position. Load vectoring can be utilized to improve hotspot thermal performance by providing increased contact pressure at hotspots.
