Hi Huginn,
The Alphacool GPX range is of course very new so only now are reviews starting to be published.
The GPX works in two ways the GPU core is actively cooled by direct contact to the GPU core block. The base of the core block has two levels, one touches the core the other touches the plate so the plate is also cooled by the block.
Because of this design your GPU will be cooled perfectly and there is only a minimal difference between that and full cover block. In fact it is even cooler then some full cover blocks
