An apparatus includes a microchannel structure that has microchannels formed therein. The microchannels are for transporting a coolant and are intended to be proximate to an integrated circuit to transfer heat from the integrated circuit to the coolant. The apparatus further includes a cover positioned on the microchannel structure. The cover has formed therein a right-angle passage to provide fluid communication between a first port on a lower horizontal surface of the cover and a second port on a vertical surface of the cover. The cover includes a plurality of tabs. Each tab extends from a respective corner of the cover. The tabs each have an aperture formed therein. The apertures are shaped and sized to receive a fastener.
