On the subject of shrouds (put your browser to full screen to get all of this, or download the image):
This is from an earlier set of test runs, can't be compared directly with the current set of runs.
Hmm. From examining this data I can see that my memory was wrong: shrouds made no difference until getting up to a 150 cfm fan, where s shroud actually improved cooling. The two H101 runs show a typical variation.
Now I suppose I'll have to re-do the shroud runs with the more precise techniques I use now.
