well, I replied in the other thread(which should be read as well), but i'll comment here too. problems,
1. unless you're using both copper and aluminum in a loop you shouldn't be using coolant with your setup, glycol is less effective at heat transfer than straight water, it is used primarily to stop corrosion or lower the freezing point of coolant(not an issue). most copper only setups use water with additives to stop organic growth.
2. Do not use those pelts on the cpu or gpu (well, maybe on the gpu, but that's iffy), they aren't powerfull enough.

comments in addition to the other thread, use a rad, and put a shroud between it and the fan, if possible a fan on either side of the rad. rad size is somewhat of a personal choice, one sized similarly to that heatsink would at least get you better results than air cooling. basically ditch the pelts and that pitiful excuse for a radiator, and tell them to come back when they've designed something thats less complicated and more efficient, in other words, an improvement, not a step backwards.
check out This article for some good design basics. I would also check out the articles section for some good reading. and I would second the flow issue. Higher flow through a loop is better. just a guess, but i would classify what you're getting with that setup as "anemic" try the old "bucket test" to see what kind of flow rates you're really getting (since mfg. max flow ratings for a pump are NOT what you're getting in a loop) also, take a look at some of the waterblock construction threads to get some basic ideas of how a reasonably effective wb is constructed. basically, in your place, i would be rightfully pissed at someone trying to pass this off as a quality watercooling system, especially at the implication that it "can't be improved upon" (although technically that might be the case if they want you to use those parts. garbage in, garbage out.) dare I ask what kind of cost they're trying to get out of it? for under $50 you can get a top of the line heatsink, and for around $100 you can get a thermaltake aquarius, which while not a good performer, is quiet and performs about the same as an air-cooling solution. I'd tell them to get lost regardless of price, but that's just me.
