on the noisy fan issue--

have you ever ran a fan controller on the fan....and play with the different settings....

Personally, I have a vortex 483 and if i run it on full blast....my tent is around 82F....but if i lower the fan speed....it lowers it to 74F and is much more quiet....i dont know why its a lower temp, maybe it pulls the cold air from the room slower over the light...i have no clue.....but i just started on the lowest setting and monitored the temps....then adjusted to the next setting on the next day and monitored till i found my best speed configuration....my fan is much more quieter on the lower setting than on full blast! good luck!
