water cooling more then cpu

now i was thinking that cooling everything with water that needs it is a smart idea. I am talking about Northbridge and gpu also and maybe devising something for Grafix card ram. Well the problem i see is that after the water hits the cpu it will be closing in on 75-80F degrees and that won't cool the NB or the GPU to well . So is it a good idea to get maybe a small aquarium pump and a small radiator along with the big Eheim and the big radiator to cool these to things by themselves.

I have all three of mine cooled, I have a temp probe before and after the CPU, the water temp after hitting the cpu block only raises a few degrees, so this really isnt a problem.

really, I thought the water would get super hot well guess i will do them all on one line a penny saved is a penny earned or something like that
