uhm... better to make some tests... same pump, radiator.
Enlarging the area spreading heat (using a copper plate, better with fins/microchannels) should be better than using the bare chip area. Air cooling teach that enlarging the area spreading heat by using well designed copper/aluminium heatsink and a good fan helps to make the job. To obtain an airflow effective enough to cool a bare cpu area you need a fan strong as a B52 helix, that's a bit complicated. Better apply an heatsink on it. Nearly the same should be for water cooling (with regard about density and uncompressibility, then using a waterblock with fins or microchannels).... Clearly, if you use a fireman's pump direct on cpu die you have no need of copper plates or waterblocks!!
