Maybe leave a metal rim around the processor, exposing the chip?The processor cannot be installed with the cover removed.
You need a Thermal Grizzly Direct Die Frame.

I'm thinking of making a through slot for the chip in the sole of the water cooling radiator. The thermal grizzly direct die frame is not suitable.
