Oh yeah, most definitely better than nothing. You'll probably find you can get better than 1-2° during certain times of year and even certain times of day. But you may also find that during the worst times of day you get practically nothing. A fairly simple solution to help you get more out of this cooling method would be to duct air to the fan and use a desiccant in the duct to dry the air out before you blow it over your tank. You can either purchase silica gel desiccant or you can just salvage a bunch from those little packets they put in almost anything you buy these days. You can recharge the desiccant by heating it slightly to drive off the moisture. Here are some examples: http://www.desiccantcity.com/desProducts.htm
