A cold plate is forced against a hat structure of a thermal conduction module (TCM) by a circular ridge protruding from a load distribution plate. The plate sandwiches the cold plate to the hat by peripheral bolts which pass through clearance holes in the plate located around the perimeter. Also contained in the plate are two larger holes for inlet and outlet plumbing fittings for chilled water. The circular ridge is located at a position away from the perimeter of the cold plate and transmits the force of the peripheral bolts to the cold plate and the hat. The conventional center bolts are not used and the cold plate cavity has additional space for an improved fin pattern. Wide channels are machined into the cold plate rather than conventional narrow channels.
