Hey man, best of luck with this grow. I noticed you were having heat problems early on.

How big is your exhaust fan? Your going to need a pretty beefy one to get an optimum flow rate through those 90 degree bends in your tubing...(two 45 degree bends are better than 1 90.

The air works under the same principles as a fluid, and putting bends in the tubing (as well as the tubing itself) causes a shit load of friction that your fan must fight against, therefore making it not work at its optimal range.

I would suggest keeping it straight and short because the ribs on the inside of the tubing also cause friction which makes the fan work harder (if it can).

Just a thought =-)
