Hi Ian
I was of the same opinion as you so I have already reversed the fan
I was hoping some gurus out there could assure me of the correct direction
. Bsically the main mirror is well enclosed in this design so I thought perhaps a cooling fan should indeed suck instead of blow..?
I don't have a temp sensor on the mirror but I guess that might be an interesting exercise? I guess a sensor outside the tube to measure ambient air temp would be a useful comparison too? Any recomendations? Jaycar perhaps?
