Cooling of the root zone is generally an issue for hydroponic growers.

Perhaps you can freeze some 2 liter coke bottles, and place them behind your oscillating fan. This will draw cool air for a while. Replace as necessary. Monitor your Relative Humidity. In flower; You want to keep humidity at around 40%
