the temps in the beginning were controlled by a cool tube, but it cracked and started smeeling up the place, so I looked for an alternative, and saw the adjust a wing with a cool tube, I just could not find one quick enough, so I bought an adjust a wing, but the temps started to soar. Had to get a bigger inline fan, I am using a 150mm L1 Ruck, it moves alot more air than the 125tt that I had. The temps are stable, but I dont know what will happen when the summer comes. I am using bottled water. Low EC and quick access, dont have to wait 24hrs for the clorine and other gases to come out.
