Cathar and j14ast, thanks for the links. Again a few hrs reading

few hrs later
Cathar's frist link is about what I mean, but with a channeled desighn for feeding the pump, and a housing of copper. His second try sure is nice, but he will lose half of pumping power as the inlet is not centerd.
Maybee with the additional pump mod (link 2), to get enough head from a small pump.
j14ast, I think you misreaded my idea. The water won't stay still at the hot-spot, it will be in turbulance. With loads of other waterblocks, the water takes on only a portion of the heat, one of the reasons why a bigger pump will do good. Not that much for the additional waterflow, but the increase of turbulance. With the impellor givving activly turbulance, where is not the need for a big pump......
Hmmmm... I guess I will make some drawings. Nice mod for a later date!
