Picture #3, Rev. 4 DONE The fan is mounted in the third plate down from the top. The extra space between plate 3 and 4 is to accommodate the height of the Davis fan. I also had to add a piece of plexi (3/4" X 4 7/8") a couple plates further down to keep the Temp. probe 'centered' in the chamber. Oh, yeah, the temp. probe I used is the Davis 'standard' probe (7817), I just cut the plug end off and twisted the black/red together, then the same for the green/yellow to make the 2-wire set up needed for the 6345. IT WORKS
With the fan in it, my temps are more in line with all the others.
