A heat removal system for a computer has a heat sink and a spool rotatably disposed in the heat sink. The spool includes fluid inlets and outlets, and water circulates in a closed loop from the inlets, through the spool, through the outlets, past the computer component to be cooled, and between the heat sink and the spool to transfer heat to the heat sink, then back to the inlets. A thermally conductive can is between the heat sink and spool such that the working fluid flows between the can and spool.
