What will your testing set up & methods be?
Copyman,
Thank you for providing some hard info, and I'm glad to see that the rad is smaller than I thought it might be.
I'm afraid I didn't understand which of the fans you've spec'd were used when you obtained the results you posted early in this thread. Could you please restate that info?
Did you do testing on the ideal distance for the shrouds stand off from the fins? What stand off distance did you decide on?
Are the flat tubes you used in your rad dimpled on the sides to increase turbulence in the tubes, or did you find the smooth walled ones to be better performers due to higher flow rates?
A interesting thread & rad.

with relationship to the rad that I sent to the cathar, to him prove the right of doing the use that to want
in those tests I was using 4 addas of 89cfm 25mm, soon later I changed for two tt of 79cfm 25mm without losses, today I use adda 105 cfm 38mm that are more silent, I already tested also with global win 130 cfm, they snore as ferrary, but not of the low differentiates in performance for the tt of 79cfm
as i said, today I use more two peltiers of 70w for my radeon 9800 for having enclosed to the system, and I don't still get a temperature elevation of liquid that it gets to measure, he is never larger than 1c above the temperature of room
with the fans of 105 cfm 38mm...
with relationship to the tests, of that model they were 13 prototypes of it blushes, one more 15 of cameras, the tests were made using a reservoir of 1,5 liters of fluid with a heater of 600w, with a bomb mag drive 700 in a circuit going by a tc4, but without him to be in activity, to approach of the real flow of the system, always using fans of 89cfm adda
The turbulence is in relation to the air, because they are 3 arrays of flat tubes opposed , look at the pictures of the it core open
