Do the chips stand-out above the cage rim?

Things to consider:

- bring it to the level of the cage rim and use thin thermoconducting foil/paste instead of the copper spring lever

- bring it below the cage rim and use thermoconducting foam of appropriate thickness

To achieve that one can consider building the PCB with low-profile, through-hole sockets for example. This might be difficult with prototyping boards though.
