an excerpt just for you:
An interesting situation exists with the Swiftech 462-U and the 462-UH as they are the same wb, but with different connection sizes. Comparing their "C/W"s it is easy to see that flow per se does not do the 'cooling', else their positions would be reversed. To look at the effect of inlet flow velocity (more accurately die area impingement velocity), in place of the very large bore (0.57 in. ID) inlet connection initially tested with the 462-UH, a Swagelok barbed connector with a 0.39 in. ID was substituted. The outlet was not changed and the standoff from the bp surface was the same for both (but greater than the 462-U). It can be seen that the performance of the 0.39 in. ID inlet is substantially improved over the larger connection having lower impingement velocity.
