I just installed two 250w Mh's with icecap ballasts on my 55 along with 220 w Pc's of actinics, they are running on icecap ballasts. I am having a problem with temperature no surprise there. Temps are ranginging from 80F at night to 86 during the day. Question is has anyone used these fans and would they be sufficient to bring my temps down a few degrees. They cought my attention because they are 120v ac.
