Fan helps a lot, my little Iceprobe chiller isn't cutting it during the summer time. I put my fan on the same timer as my MH lights. When the MH come on, so does the fan. My chiller is on the timer my actinics are on.
I did the same thing as klam. Fan on same timer as the MH lights. It's a 6" desktop fan that I mounted to the back of the hood. I also have 2 small PC fans built into the hood but they don't do diddly.
