That's a bad radiator design for water cooling...
Think about it.. Most of the water would go right through the center of the tube without ever touching the walls..
Not only that, but the tube itself is blocking all that airflow.. Air would be bouncing straight back off of the tube instead of going through the fins..
The fins don't have much contact with the tube.. The fins will be much colder than the water flowing through the center of the tube because there just isn't much contact between the tube and the fins. The fins will be hottest the closer they are to the tube, but at the same time your airflow will be WORSE the closer you are to the tube because air will be bouncing back off the tube at odd angles since it's so thick.
Finally, the tube has a lot of 180 degree bends in it which can cause more restriction.
Now take a look at any of the radiators in a regular water cooling kit, they have dozens of tubes that go the full length and have fins contacting each tube dozens of times per inch. The tubes themselves don't block much airflow because they're so thin.. Also because they're so thin, you don't have so much water tunneling straight down the center without ever making contact with the tube.
Further, isn't that giant hunk 'o metal aluminum?
I think thing was designed for fanless cooling.. Certainly wasn't meant to have air blown through it or they wouldn't have put the tube through the middle of it so many times and made the tube so thick. Take a look at a car radiator that's meant to have air blowing through it and you'll see it has more in common with water cooling radiators.Edited by Sidicas - 2/11/11 at 5:53pm
