Firstly, unlike a car radiator, there are no cooling fins on this 'CPU radiator' to transfer the heat to the air flowing through the radiator, and therefore secondly, unlike a car radiator, there is no cooling fan (or fans) to move the air through the 'CPU radiator' (as veedubfreak stated).
The purpose of the tubes in the 'CPU radiator' is to transfer heat from the core or heatspreader of the CPU to the fluid, and not the immediate surrounding air, which is what a car radiator does, or what the CPU cooler would have done originally before the fan was removed and the cooling fins were chopped off.
If you think of the 'CPU radiator' as just a radiator cooling the CPU by transferring heat to the immediate surrounding air, then it is a very poor one, since it's missing vital elements such as cooling fins and a fan. It's not a conventional heatpipe heatsink anymore.

Alvin this is not a radiator, its a waterblock

woah, alvin, you didn't start your post with, hello. haha. yeah it would make more sense to break it up into 2 radiators and do like a 1 2 1 2 system so it's evenly dispersed.

Honestly, it is a good idea, but the best thing to do, is build it more like a mini heater core that would be in a car, have a few tubes similar, then on top have the fan, similar to the liquid filled heat sinks, but allowing the water to actually go to another fan and cool down even further... Meh, just an idea, btw, rubbers and plastics aren't a great heat conductor, so even a fan or the ambient air in the system wouldn't cool those enough to help.

What a stupid idea. For watercooling to be effective you need to eliminate laminar flow and make it as turbulent as possible to maximize heat transfer.
Also since the inside of the tubes are just smooth and flat there's not much surface area to transfer heat into the water. Tardacious.

Yes, but what he's saying is that as long as the flow of water is uninterupted your not going to see great performance.
Water running along a smooth surface at high speed will not absorb as much heat as a slower more turbulent flow. | |
