Technologies for isolated heat dissipating devices

A heat sink comprising:

• a first sub-heat sink comprising a first heat sink base and a first plurality of heat sink fins attached to the first heat sink base;
• a second sub-heat sink comprising a second heat sink base and a second plurality of heat sink fins attached to the second heat sink base;
• and
• one or more fasteners mechanically coupling the first sub-heat sink to the second sub-heat sink,
• wherein the first sub-heat sink is not thermally coupled to the second sub-heat sink.

A system comprising:

• a water block comprising an inlet and an outlet, wherein the inlet is connected to the outlet by an internal channel defined in the water block;
• an integrated circuit component comprising a first die and a second die;
• a first thermoelectric cooler thermally coupled to the first die and the water block;
• and
• a second thermoelectric cooler thermally coupled to the second die and the water block.
