1. An apparatus comprising:a first housing comprising a surface operable to receive heat from a heat-generating component, wherein the first housing includes a first component, a second component, and a third component coupled together to form a cavity to contain a liquid;
a second housing comprising a receptacle operable to receive the first housing, wherein the receptacle is operable to inhibit movement of the first housing along a first axis and facilitate movement of the first housing along a second axis,
wherein the first housing is moveable within the receptacle along the second axis and movement of the first housing along the second axis is operable to change a size of a gap between the surface and the heat-generating component;
a first tube and a second tube connecting the first housing and the second housing, wherein the first and second tubes transfer the liquid in the cavity between the first housing and the second housing; and
a threaded shaft extending between opposing faces of the first housing and the receptacle, wherein the threaded shaft is lockable to fix a position of the first housing along the second axis and to fix the size of the gap.
