Adding water-cooling for my 9700PRO to my CPU cooling system

I have a water-cooled 2100xp. I run the radiator without a fan most of the time and it gets up to 50c under load. If I run the fan it gets up to 40c under load; do you think that is too high or about right? I will be WCing my 9700pro (I'm doing this to reduce noise, not OC) and was wondering if the 50c water will actually heat the Radeon instead of cool it. I wasn't going to run the two water blocks in series but instead run them in parallel (I may even run a separate return line from the Radeon to the reservoir. I've read that it might be better to run them in series, any thoughts?

Do you think the cooling system can handle the extra heat and do you think it's too hot for my Radeon? Also, I'm running a crappy maxtor radiator that I got for next to nothing. Do you think I would see a temp drop with a large heater core? The rad is not in my case so size doesn't really matter. I was thinking of a heater core out of a Ford F-250 or somthing similar.

I have innovatek rev3 cpu block and graph-o-matic rev2 GPU block.
All suggestions are welcome and appreciated!
 
I'm afraid you'll quickly find a point of diminishing returns using those block. They offer mediocre performance at best. They're just too restrictive for high performance.

Appriciated but..

*High Performance* isn't really what I'm going for, more cool/quiet. (I have the radiator/fan setup in the basement which removes the heat and noise from my computer room.) I've had the CPU block for a long long time, I got the GPU block because I didn't see the point in trying to use different sized hose when the CPU block was already a bottle neck. Still, 40c under full load isn't that bad is it?
 
Not bad at all. I doubt the added gpu block will impact temperatures that much. Maybe too much to run passive but the fan it should keep you safe.
 
Do you guys think parrelell or series for my setup?

Parrelell
(two lines after split, one to CPU and one to GPU. two lines returning to resevoir)
radiator->split(from one line to two)->

line1->CPU->resevoir
line2->GPU->resevoir

or Series...

radiator->GPU->CPU->resevoir
